-1 Introduction
-**************
-
-This manual (dated April 2014) corresponds to the TeX Live 2014 release.
-
- This manual is aimed at system installers and programmers, and
-focuses on how to configure, build, and develop the TeX Live (TL)
-sources. The sources can be acquired in a number of ways: see
-<http://tug.org/texlive/svn>.
-
- This manual does not duplicate the (primarily user-level) information
-found in other TL documentation resources, such as:
-
- * The TeX Live web pages: <http://tug.org/texlive>.
-
- * The TeX Live user manual: <http://tug.org/texlive/doc.html>, or run
- 'texdoc texlive'.
-
- * Other TeX-related Texinfo manuals (*note (web2c)::, *note
- (kpathsea)::, etc.): <http://tug.org/texinfohtml/>, or check the
- 'TeX' category in the GNU Info system.

-2 Build system
-**************
-
-The TeX Live build system was redesigned in 2009, consistently using
-Autoconf, Automake, and Libtool. Thus
- 'configure && make && make check && make install'
-or the basically-equivalent top-level 'Build' script suffice to build
-and install the TL programs. The 'make check' clause performs various
-tests of the generated programs--not strictly required but strongly
-recommended. Running 'configure --help' will display a comprehensive
-list of all 'configure' options.
-
- The main components of the TL build system are:
-
-'texk/LIB'
- TeX-specific libraries in subdirectories, notably LIB='kpathsea'.
- (The other one is 'texk/ptexenc'.)
-
-'texk/PROG'
- TeX-specific programs (that use Kpathsea).
-
-'utils/PROG'
- Other programs (that don't use Kpathsea).
-
-'libs/LIB'
- Generic libraries.
-
- The primary design goal of the build system is modularity. Each
-program and library module (or package) specifies its own requirements
-and properties, such as required libraries, whether an installed
-(system) version of a library can be used, 'configure' options to be
-seen at the top-level, and more. An explicit list of all available
-modules is kept in only one, central, place ('m4/kpse-pkgs.m4').
-
- A second, related goal is to configure and build each library before
-configuring any other (program or library) module which uses that
-library. This allows checking for properties and features of a library
-built as part of the TL tree in much the same way as for a system
-version of that library.
-
- All generic libraries and several programs are maintained
-independently. The corresponding modules use (most of) the distributed
-source tree and document any modifications of that source tree.
-
- All this is for the sake of simplifying both upgrading of modules
-maintained independently and integrating new modules into the TL build
-system. (Not to say that either task has become trivial.)

-2.1 Prerequisites for building TeX Live
-=======================================
-
-Overall, building the TeX Live programs, when using all libraries from
-the TL source tree, requires only C and C++ compilers and GNU 'make'.
-(If 'make' from your 'PATH' is not GNU make, you can set 'MAKE' in the
-environment to whatever is necessary.)
-
- Indeed, GNU 'make' is required only because of some third-party
-libraries, notably FreeType; all the TL-maintained directories (and
-Automake/Autoconf output in general) should work with any reasonable
-'make'.
-
- However, a few programs in the tree have additional requirements:
-
-'biber'
- requires 'perl' for autodetection of the TL platform name.
-
-'xdvik'
-'xpdfopen'
- require X11 headers and libraries, often a "development" package
- that is not installed by default.
-
-'xetex'
- requires 'fontconfig' (again both headers and library).
-
-'xindy'
- requires GNU 'clisp' and in addition 'perl', 'latex', and
- 'pdflatex' to build the rules and/or documentation.
-
-Lacking the required tools, building these programs must avoided, e.g.,
-'configure --disable-biber --without-x --disable-xetex --disable-xindy'.
-
- Modifying source files also induces more requirements:
-
- * Modification of any '.y' or '.l' source files requires 'bison' or
- 'flex' to updatete the corresponding C sources.
-
- * Modification of the sources for '.info' files requires 'makeinfo'.
-
- * Modification of any part of the build system (M4 macros,
- 'configure.ac', 'Makefile.am', or their fragments) requires GNU M4,
- GNU Autoconf, GNU Automake, and GNU Libtool to update the generated
- files. *Note Build system tools::.

-
-2.2 Building
-============
-
-The top-level 'Build' script is intended to simplify building the
-binaries distributed with TeX Live itself--we call this the "native" TL
-build. It configures and makes everything in a subdirectory of the main
-build tree (default 'Work/'), installs everything in an other
-subdirectory (default 'inst/'), and finally runs 'make check'. The
-exact directory and command names can be specified via environment
-variables and a few leading options. All remaining arguments
-(assignments or options) are passed to the 'configure' script. Please
-take a look at the script itself for more information; it is not
-complicated.
-
- An alternative, and the one we will mainly discuss here, is to run
-'configure' and 'make' oneself in a suitable empty subdirectory.
-Building in the source directory itself is not supported (sorry).
-
- Running the top-level 'configure' script configures the top level and
-the subdirectories 'libs', 'utils', and 'texk'. Running 'make' at the
-top-level first iterates over all TeX-specific libraries, and then runs
-'make' in 'libs', 'utils', and 'texk' to iterate over all generic
-libraries, utility programs, and TeX-specific programs. These
-iterations consist of two steps:
-
- 1. For each library or program module not yet configured, run
- 'configure', adding the configure option '--disable-build' if the
- module need not be built, otherwise running 'make all'.
-
- 2. For each library or program module that must be built, run 'make'
- for the selected target(s): 'default' or 'all' to (re-)build,
- 'check' to run tests, 'install', etc.
-
- Running the top-level 'make' a second time iterates again over all
-the library and program modules, but finds (should find) nothing to be
-done unless some source files have been modified.
-
- If configuring or building a module fails, you could either (a) find
-and fix the problem, or (b) remove the subdirectory for that module from
-the build tree, and rerun the top-level 'make' (or 'Build' with
-'--no-clean' as its first argument).
-
- With the configure option '--disable-all-pkgs', all program and
-library modules are configured but none of them is built. The
-'Makefile' for each such module contains all build rules and
-dependencies and can be invoked to build an individual program or
-library and causes to first build any required libraries. This
-"build-on-demand" procedure is used, e.g., in the 'luatex' repository to
-build LuaTeX, essentially from a subset of the complete TeX Live tree.
-Similarly, when, e.g., building the original e-TeX has been disabled (as
-it is by default), one can run 'make etex' (or 'make etex.exe') in
-'texk/web2c/' to build e-TeX (although there is no comparably simple way
-to install e-TeX).
-
- The TL build system carefully formulates dependencies as well as
-'make' rules when a tool (such as 'tangle', 'ctangle', or 'convert')
-creates several output files. This allows for parallel builds ('make -j
-N' with N>1 or even 'make -j') that can considerably speed up the TL
-build. Independently, speed-up can also be achieved by using a
-configure cache file, i.e., with the option '-C' (recommended).
-
- Running 'make dist' at the top-level creates a tarball
-'tex-live-YYYY-MM-DD.tar.xz' from the TL source tree. Running 'make
-dist-check' also verifies that this tarball suffices to build and
-install all of TL. (This is useful for checking consistency of the
-source tree and Makefiles, but the result is not a complete or even
-usable TeX system, since all the support files are lacking; see the next
-section.)

-
-2.3 Installing
-==============
-
-This section discusses the results of 'make install' in the source tree.
-
- The main consideration is that this is not enough to make a usable
-TeX installation. Beyond the binaries that are built from the sources,
-(thousands of) support files are needed; just as a first example
-'plain.tex' is not in the source tree.
-
- These support files are maintained completely independently and are
-not present in the source tree. The best basis for dealing with them is
-the TeX Live (plain text) database in 'Master/tlpkg/texlive.tlpdb',
-and/or the TeX Live installer, 'install-tl'. More information is under
-'Master/tlpkg' and at <http://tug.org/texlive/distro.html>.
-
-* Menu:
-
-* Installation directories:: The prefix, 'bindir', etc., directories.
-* Linked scripts:: Scripts not maintained in the sources.
-* Distro builds:: Configuring and building for OS distributions.
-
-
-File: texlive.info, Node: Installation directories, Next: Linked scripts, Up: Installing
-
-2.3.1 Installation directories
-------------------------------
-
-Running 'make install' (or 'make install-strip') installs executables in
-'BINDIR', libraries in 'LIBDIR', headers in 'INCLUDEDIR', general data
-(including "linked scripts", *note Linked scripts::) in
-'DATAROOTDIR/texmf-dist', man pages in 'MANDIR', and Info files in
-'INFODIR'.
-
- The values of these directories are determined by 'configure' and can
-be specified explictly as options such as '--prefix=PREFIX' or
-'--bindir=BINDIR'; otherwise, they are given by their usual Autoconf
-defaults:
-
- PREFIX /usr/local
- EXEC_PREFIX PREFIX
- BINDIR EXEC_PREFIX/bin
- LIBDIR EXEC_PREFIX/lib
- INCLUDEDIR PREFIX/include
- DATAROOTDIR PREFIX/share
- MANDIR DATAROOTDIR/man
- INFODIR DATAROOTDIR/info
-
-... except possibly modified as follows:
-
- * If the option '--enable-multiplatform' is given, '/PLATFORM' (i.e.,
- the canonical platform name) is appended to 'BINDIR' and 'LIBDIR'.
- This is implied for a native TL build.
-
- * In a native TL build, 'DATAROOTDIR' is set to 'PREFIX', 'INFODIR'
- is set to 'PREFIX/texmf-dist/doc/info', and 'MANDIR' to
- 'PREFIX/texmf-dist/doc/man', corresponding to the directories used
- in the TL distribution.
-
-The top-level 'configure' script displays all these installation paths.
-
- For the native TL build, the 'Build' script leaves the binaries in
-'./inst/bin/STD-PLATFORM-NAME'. The new binaries are not directly
-usable from that location; they need to be copied to
-'Master/bin/TL-PLATFORM'. The other files and directories that end up
-in './inst/' are ignored.
-
-
-File: texlive.info, Node: Linked scripts, Next: Distro builds, Prev: Installation directories, Up: Installing
-
-2.3.2 Linked scripts
---------------------
-
-Quite a few executables are architecture-independent shell, Perl, or
-other scripts, rather than compiled binaries. A few are maintained as
-part of the TL source tree, but most are maintained elsewhere with
-copies under 'texk/texlive/linked_scripts'. These are installed under
-'DATAROOTDIR/texmf-dist/scripts'; for Unix-like systems a symbolic link
-is made in 'BINDIR'. For example, a symlink points from 'BINDIR/ps2eps'
-to 'DATAROOTDIR/texmf-dist/scripts/ps2eps/ps2eps.pl'.
-
- For Windows, a standard wrapper binary (e.g., 'BINDIR/ps2eps.exe')
-serves the same purpose. (The source for it is in
-'texk/texlive/w32_wrapper'.)
-
- One reason for all this is to avoid having many copies for the same
-script, but most importantly this allows invoking the same script on all
-operating systems. Furthermore, we want the 'BINDIR' resulting from the
-build to be exactly what is in the TL distribution; any deviations cause
-considerable extra work.
-
-
-File: texlive.info, Node: Distro builds, Prev: Linked scripts, Up: Installing
-
-2.3.3 Distro builds
--------------------
-
-Although they use the same code base, building for the native TL
-distribution as shipped by the TL user groups is typically quite
-different from a "distro" build needed by, e.g., a full GNU/Linux or BSD
-operating system distribution.
-
- The native TL distribution uses shared libraries only when absolutely
-necessary ('libc', 'libm', X11 libraries, and 'libfontconfig').
-However, a distro typically wants to use as many shared libraries as
-possible from elsewhere on the system, including TeX-specific libraries
-such as 'libkpathsea' (even though Kpathsea has never officially been
-released as a shared library, but we digress). In addition, the
-installation paths will, in general, be completely different.
-
- Here are the 'configure' options that distro builds are likely to
-find most relevant:
-
-'--disable-native-texlive-build'
- This must be specified to avoid interference from the many tweaks
- we do for the native TL build.
-
-'--with-banner-add=/SOMEDISTRO'
- This isn't technically required, but is strongly recommended, so
- your build and your distro can be distinguished from others.
-
-'--enable-shared'
- Build shared versions of the TeX-specific libraries (uses
- 'libtool').
-
-'--disable-static'
- Do not build the static versions of the TeX-specific libraries.
-
-'--with-system-LIB'
- Use system versions for as many libraries LIB as possible.
- 'configure --help' will give you the list of possibilities.
-
-'--with-LIB-includes=DIR'
-'--with-LIB-libdir=DIR'
- If needed, allows you to specify where the headers/code are for the
- given library LIB.
-
-'--prefix=/usr'
-'--prefix=/opt/TeXLive'
- Or whatever your convention is. The default is '/usr/local' and
- you shouldn't install there for a distro.
-
-'--libdir=\${exec_prefix}/lib64'
- May be needed for 64-bit bi-architecture (GNU/Linux) systems.
-
- You will need to take care of the support files mentioned above
-(*note Installing::), and many other issues, such as font maps,
-languages, and formats, independently of the build. Norbert Preining
-has written a detailed article on adapting TL for distros:
-<http://tug.org/TUGboat/tb34-3/tb108preining-distro.pdf>. (If it needs
-updating at some point, perhaps we will merge it into this document.)

-2.4 Infrastructure and layout
-=============================
-
-The TeX Live source tree is the subtree rooted at 'Build/source' of the
-complete TL distribution and contains the sources for all executables
-distributed by TL, as well as 'configure' scripts and 'make' rules to
-build and install them together with some of their support files.

-* Extending TeX Live:: Adding a new module.
-
-
-File: texlive.info, Node: Build system tools, Next: Top-level directories, Up: Infrastructure and layout
-
-2.4.1 Build system tools
-------------------------
-
-As mentioned above (*note Prerequisites::), a normal build requires very
-little. On the other hand, if you want to modify the TeX Live
-infrastructure sources, such as 'configure.ac' or 'Makefile.am' files,
-you will need to have several additional tools installed.
-
- In general, the TL build system uses the latest released versions of
-the GNU build tools, installed directly from the original GNU releases
-(e.g., by building them with 'configure --prefix=/usr/local/gnu' and
-having 'PATH' start with '/usr/local/gnu/bin'). We have found that
-trying to use the versions of these tools packaged for distros causes
-many extra hassles, so don't do that, tempting as it may be.
-
- Currently the versions we use are:
-
- autoconf (GNU Autoconf) 2.69
- automake (GNU automake) 1.14.1
- bison (GNU Bison) 3.0.2
- flex 2.5.39
- ltmain.sh (GNU libtool) 2.4.2
- m4 (GNU M4) 1.4.17
- makeinfo (GNU texinfo) 5.2
-
- These versions should be used to update the generated files (e.g.,
-'configure' or 'Makefile.in') in all or parts of the TL tree after their
-dependencies have been changed. This can be done explicitly with the
-top-level 'reautoconf' script or implicitly by using the configure
-option '--enable-maintainer-mode'.
-
- The files in the Subversion repository (see
-<http://tug.org/texlive/svn>) are all up to date, but unfortunately this
-may not be reflected by their timestamps. (For starters, be sure to set
-'use-commit-times=yes' in '~/.subversion/config' or the equivalent.)
-
- To avoid unnecessary runs of 'bison', 'flex', or 'makeinfo' it may be
-necessary to 'touch' the generated ('.c', '.h', or '.info') files. With
-'--enable-maintainer-mode' it may also be necessary to 'touch' first
-'aclocal.m4', then 'configure' and 'config.h.in' (or 'c-auto.in'), and
-finally all 'Makefile.in' files. Perhaps 'make -t' will help.
-
-

-
-2.4.2 Top-level directories
----------------------------
-
-Here is a brief description of the top-level directories in the TeX Live
-source tree.
-
- As mentioned at the beginning of the chapter (*note Build system::),
-the main source directories are 'texk/' (TeX-specific programs and
-libraries), 'utils/' (additional programs), and 'libs' (generic
-libraries).
-
- The top-level directories 'am/' and 'm4/' contain 'Makefile.am'
-fragments and Autoconf macros, respectively, used in many places.
-Specifically, the file 'm4/kpse-pkgs.m4' contains lists of all program
-and library modules; missing modules are silently ignored. (This helps
-in creating cut-down source trees.)
-
- Each module contributes fragments (in separate files) defining its
-capabilities and requirements to the 'configure.ac' scripts at the
-top-level and in the subdirectories 'libs', 'utils', and 'texk'. The
-fragments from program modules supply 'configure' options to disable or
-enable building them; those from library modules specify if an installed
-(system) version of that library can be used. This ultimately
-determines which modules need to be built--although all modules must be
-configured for the benefit of 'make' targets such as 'dist' or
-'distcheck'.
-
- The top-level 'build-aux/' directory contains the common files
-'compile', 'config.guess', 'config.sub', 'depcomp', etc. for most
-packages, pulled from the GNU Gnulib sources
-(<http://www.gnu.org/software/gnulib>), which in turn synchronizes with
-the appropriate ultimate upstream repository. There are, however,
-independent copies in, e.g., 'libs/freetype2/freetype-*/builds/unix/',
-and similar places. The 'reautoconf' script does not touch those, but a
-TL cron job keeps them in sync (nightly).
-
- The directory 'extra/' contains things which are not part of the TL
-build, but are present for convenience, e.g., 'epstopdf' developed here
-and 'xz/' required by the TL installer.

-2.4.3 Autoconf macros
----------------------
-
-Here we describe some of the Autoconf macros used in several modules-not
-a complete list, by any means. These general macros are supplemented by
-module-specific macros in directories such as 'texk/dvipng/m4/'; some of
-those are described in *note Library modules:: and *note Program

- 'AM_INIT_AUTOMAKE([foreign MORE-OPTIONS])'
- 'AM_MAINTAINER_MODE'
- 'KPSE_COMPILER_WARNINGS'
- and make sure the C compiler understands function prototypes. This
- is used for all generic library and program modules.
-
- -- Macro: KPSE_COMMON (NAME, [MORE-OPTIONS])
- Like 'KPSE_BASIC' but add:
- 'LT_PREREQ([2.2.6])'
- 'LT_INIT([win32-dll])'
- 'AC_SYS_LARGEFILE'
- 'AC_FUNC_FSEEKO'
- and check for frequently used functions, headers, types, and
- structures. This is used for TeX-specific modules.

-
-Macros for program checks:
-
- -- Macro: KPSE_CHECK_LATEX
- Set 'LATEX' to the name of the first of 'latex', 'elatex', or
- 'lambda' which exists in 'PATH', or to 'no' if none of them exists.
- Call 'AC_SUBST' for 'LATEX'. The result of this test can be
- overridden by setting the 'LATEX' environment variable or the cache
- variable 'ac_cv_prog_LATEX'.
-
- -- Macro: KPSE_CHECK_PDFLATEX
- Check for 'pdflatex' in 'PATH' and set 'PDFLATEX'.
-
- -- Macro: KPSE_CHECK_PERL
- Check for 'perl' or 'perl5' in 'PATH' and set 'PERL'.
-
- -- Macro: KPSE_PROG_LEX
- Call 'AC_PROG_LEX' and add the flag '-l' for 'flex'.

-2.4.3.3 Macros for compilers
-............................
-
-Macros for compiler-related checks:
-
- -- Macro: KPSE_COMPILER_WARNINGS
- When using the (Objective) C/C++ compiler, set
- 'WARNING_[OBJ]C[XX']FLAGS to suitable warning flags (depending on
- the value given to or implied for '--enable-compiler-warnings').
- Call 'AC_SUBST' for them. At the moment this only works for GNU
- compilers, but could be extended to others if necessary.
-
- This macro caches its results in the 'kpse_cv_warning_cflags', ...
- variables.
-
- -- Macro: KPSE_COMPILER_VISIBILITY
- When using the C or C++ compiler, try to set
- 'VISIBILITY_C[XX]FLAGS' to flags to hide external symbols. Call
- 'AC_SUBST' for this variable. At the moment this only tests for
- the compiler option '-fvisibility=hidden', but that could be
- extended with more checks if necessary.
-
- This macro caches its results in the 'kpse_cv_visibility_cflags' or
- 'kpse_cv_visibility_cxxflags' variable.
-
- -- Macro: KPSE_CXX_HACK
- Provide the configure option '--enable-cxx-runtime-hack'. If
- enabled and when using 'g++', try to statically link with
- 'libstdc++', somewhat improving portability of the resulting

-2.4.3.5 Macros for library and header flags
-...........................................
-
-Each library module 'libs/LIB' or 'texk/LIB' is supplemented by a macro
-'KPSE_LIB_FLAGS' (all uppercase) that provides make variables for that
-library. E.g., for 'libs/libpng':
-
- -- Macro: KPSE_LIBPNG_FLAGS
- Provide the configure option '--with-system-libpng'. Set and
- 'AC_SUBST' 'make' variables for modules using this library (either
- an installed version or from the TeX Live tree): 'LIBPNG_INCLUDES'
- for use in CPPFLAGS, LIBPNG_LIBS for use in LDADD, LIBPNG_DEPEND
- for use as dependency, and LIBPNG_RULE defining 'make' rules to
- rebuild the library.
-
- -- Macro: KPSE_ADD_FLAGS (LIBNAME)
- Temporarily extend CPPFLAGS and LIBS with the values required for
- the library module 'NAME'.
-
- -- Macro: KPSE_RESTORE_FLAGS
- Restore 'CPPFLAGS' and 'LIBS' to their original values.
-
- As an example, the 'configure.ac' file for a hypothetical program
-'utils/foo' using 'libpng', and hence 'zlib', would contain
- KPSE_ZLIB_FLAGS
- KPSE_LIBPNG_FLAGS
-
-and its 'Makefile.am' would be along these lines:
- bin_PROGRAMS = foo
- AM_CPPFLAGS = ${ZLIB_INCLUDES} ${LIBPNG_INCLUDES}
- foo_LDADD = ${ZLIB_LIBS} ${LIBPNG_LIBS}
- foo_DEPENDENCIES = ${ZLIB_DEPEND} ${LIBPNG_DEPEND}
- ## Rebuild libz
- @ZLIB_RULE@
- ## Rebuild libpng
- @LIBPNG_RULE@
-
- If it was necessary to examine whether certain 'zlib' or 'libpng'
-features were available, 'configure.ac' should be continued this way:
- KPSE_ADD_FLAGS([zlib])
- ... # tests for 'zlib' features, if any
- KPSE_ADD_FLAGS([libpng])
- ... # tests for 'libpng' features
- KPSE_RESTORE_FLAGS # restore 'CPPFLAGS' and 'LIBS'

-2.4.3.6 Macros for Windows
-..........................
-
-Windows differs in several aspects from Unix-like systems, many of them
-due to the lack of symbolic links.
-
- -- Macro: KPSE_CHECK_WIN32
- Check if compiling for a Windows system. The result is 'no' for
- Unix-like systems (including Cygwin), 'mingw32' for Windows with
- GCC, or 'native' for Windows with MSVC. The result is cached in the
- 'kpse_cv_have_win32' variable.
-
- -- Macro: KPSE_COND_WIN32
- Call 'KPSE_CHECK_WIN32' and define the Automake conditional 'WIN32'
- ('true' if the value of 'kpse_cv_have_win32' is not 'no').
-
- -- Macro: KPSE_COND_MINGW32
- Call 'KPSE_COND_WIN32' and define the Automake conditional
- 'MINGW32' ('true' if the value of 'kpse_cv_have_win32' is
- 'mingw32').
-
- -- Macro: KPSE_COND_WIN32_WRAP
- Call 'KPSE_COND_WIN32' and define the Automake conditional
- 'WIN32_WRAP' ('true' if the standard Windows wrapper
- ('texk/texlive/w32_wrapper/runscript.exe') exists. This wrapper is
- used on Windows instead of symlinks for the "linked scripts" (*note
- Linked scripts::).
-
- -- Macro: KPSE_WIN32_CALL
- Call 'KPSE_COND_WIN32', check if the file
- 'texk/texlive/w32_wrapper/callexe.c' exists; if it does, create a
- symlink in the build tree. Compiling 'callexe.c' with
- '-DEXEPROG='"FOO.exe"'' and installing 'callexe.exe' as 'BAR.exe'
- is used on Windows instead of a symlink 'BAR->FOO' for Unix-like
- systems.

-2.4.4 Library modules
----------------------
-
-Here we discuss some specifics for a few of the libraries in TL, both
-for the details themselves, and as a way of illuminating the general
-structure and variation.
-
-* Menu:
-
-* 'png' library:: 'libs/libpng'
-* 'zlib' library:: 'libs/zlib'
-* 'freetype' library:: 'libs/freetype2'
-* 'kpathsea' library:: 'texk/kpathsea'
-
-
-File: texlive.info, Node: 'png' library, Next: 'zlib' library, Up: Library modules
-
-2.4.4.1 The 'png' library in 'libs/libpng'
-..........................................
-
-This generic library uses the source tree in, e.g., the subdirectory
-'libpng-1.5.17' with all modifications for TL recorded in
-'libpng-1.5.17-PATCHES/*'. The 'configure.ac' fragment
-'ac/withenable.ac' contains
-
- KPSE_WITH_LIB([libpng], [zlib])
-
-specifying the module name, and indicating the dependency on 'zlib'. A
-third literal argument 'tree' would specify that the library from the
-TeX Live tree cannot be replaced by a system version. That not being
-the case here, a second fragment 'ac/libpng.ac' contains
-
- KPSE_TRY_LIB([libpng],
- [#include <png.h>],
- [png_structp png; png_voidp io; png_rw_ptr fn;
- png_set_read_fn(png, io, fn);])
-
-thus providing the simple C code
-
- #include <png.h>
- int main ()
- { png_structp png; png_voidp io; png_rw_ptr fn;
- png_set_read_fn(png, io, fn);
- return 0; }
-
-which Autoconf uses to verify the usability of a system version with C
-code. The analogous macro 'KPSE_TRY_LIBXX' would check using C++ code.
-These fragments are included by 'configure.ac' at the top level.
-
- For this library, among many other modules, a proxy build system for
-TL is used ('configure.ac', 'Makefile.am', and 'include/Makefile.am'),
-ignoring the distributed one. Consequently, a few generated files and
-auxiliary scripts are removed from the distributed source tree. The
-public headers 'png.h', 'pngconf.h', and 'pnglibconf.h' are "installed"
-(as symlinks) under 'include/' in the build tree exactly as they are for
-a system version under, e.g., '/usr/include/'.
-
- The module is supplemented by the file 'm4/kpse-libpng-flags.m4' that
-defines the M4 macro 'KPSE_LIBPNG_FLAGS' used by all modules depending
-on this library in their 'configure.ac' to generate the 'make' variables
-'LIBPNG_INCLUDES' for use in 'CPPFLAGS', 'LIBPNG_LIBS' for use in
-'LDADD', 'LIBPNG_DEPEND' for use as dependencies, and 'LIBPNG_RULE'
-defining 'make' rules to rebuild the library.
-
- 'm4/kpse-libpng-flags.m4' also supplies the configure option
-'--with-system-libpng' and uses 'pkg-config' to determine the flags
-required for the system library.

-
-2.4.4.2 The 'zlib' library in 'libs/zlib'
-.........................................
-
-This generic library is very much analogous to 'libpng', but without the
-dependency on any other library. The file 'm4/kpse-zlib-flags.m4'
-supplies the configure option '--with-system-zlib', as well as
-'--with-zlib-includes' and '--with-zlib-libdir' to specify non-standard
-locations of the 'zlib' headers and/or library.

-
-2.4.4.3 The 'freetype' library in 'libs/freetype2'
-..................................................
-
-This module uses a wrapper build system with an almost trivial
-'configure.ac' and with a 'Makefile.am' that invokes 'configure' and
-'make' for the distributed source, followed by 'make install' with the
-build tree as destination. The flags required for the system library
-are obtained through 'freetype-config'.

-
-File: texlive.info, Node: 'kpathsea' library, Prev: 'freetype' library, Up: Library modules
-
-2.4.4.4 The 'kpathsea' library in 'texk/kpathsea'
-.................................................
-
-This is one of the TeX-specific libraries that are maintained as part of
-TeX Live (*note (kpathsea)::). Despite being a core part of the TeX
-system, it is not a terribly special case in the infrastructure. The
-TeX libraries are Libtool libraries (static and/or shared) and are
-installed by 'make install' together with the programs. They are,
-however, not part of the TL DVD as distributed by TeX user groups, and
-have never been officially released for standalone use.
-
- It is possible, and possibly even useful for distro builds (*note
-Distro builds::, to specify the configure option
-'--with-system-kpathsea' in order to use a system version of the library
-and it may then be necessary to specify '--with-kpathsea-includes'
-and/or '--with-kpathsea-libdir'.
-
- In addition to 'ac/withenable.ac' and 'ac/kpathsea.ac' there is a
-third fragment 'ac/mktex.ac' included by both 'ac/withenable.ac' and
-'configure.ac' that supplies configure options such as
-'--enable-mktextfm-default', which determine the compile time default of
-whether or not to run 'mktextfm' to generate a missing '.tfm' file. In
-any case, however, the command line options '-mktex=tfm' or
-'-no-mktex=tfm' for the TeX-like engines override this default.

-2.4.5 Program modules
----------------------
-
-As with libraries (*note Library modules::), here we discuss the details
-for a few of the programs in TL.
-
-* Menu:

-
-2.4.5.1 The 't1utils' package in 'utils/t1utils'
-................................................
-
-Once again we use the distributed source tree 't1utils-1.38' with
-modifications documented in 't1utils-1.38-PATCHES/*' and a proxy build
-system consisting of 'configure.ac' and 'Makefile.am'. The fragment
-'ac/withenable.ac' contains
-
- KPSE_ENABLE_PROG([t1utils])
-
-specifying the module name without any dependencies, and supplies the
-configure option '--disable-t1utils'.
-
-
-File: texlive.info, Node: 'xindy' package, Next: 'xdvik' package, Prev: 't1utils' package, Up: Program modules
-
-2.4.5.2 The 'xindy' package in 'utils/xindy'
-............................................
-
-This module uses the distributed source tree 'xindy-2.4' with
-modifications documented in 'xindy-2.4-PATCHES/*', a proxy
-'configure.ac', and a wrapper 'Makefile.am' that descends into
-'xindy-2.4'. The 'xindy' build requires that the distributed
-'Makefile's allow a 'VPATH' build, can handle all targets, and do not
-refer to '${top_srcdir}' or '${top_builddir}'. The fragment
-'ac/withenable.ac' contains
-
- KPSE_ENABLE_PROG([xindy], , [disable native])
- m4_include(kpse_TL[utils/xindy/ac/xindy.ac])
- m4_include(kpse_TL[utils/xindy/ac/clisp.ac])
-
-where 'disable' in the third argument indicates that 'xindy' is only
-built if explicitly enabled by the user with 'configure --enable-xindy'
-(the need for 'clisp' is too painful to require by default), and
-'native' disallows cross compilation. The additional fragments
-'ac/xindy.ac' and 'ac/clisp.ac' specify more 'configure' options to be
-seen at the top level with 'ac/xindy.ac' also included by
-'configure.ac'.
-
-
-File: texlive.info, Node: 'xdvik' package, Next: 'asymptote', Prev: 'xindy' package, Up: Program modules
-
-2.4.5.3 The 'xdvik' package in 'texk/xdvik'
-...........................................
-
-This package is maintained as part of the TeX Live tree with sources in
-its top level directory and the subdirectory 'gui'. The fragment
-'ac/withenable.ac' contains
-
- dnl extra_dirs = texk/xdvik/squeeze
- KPSE_ENABLE_PROG([xdvik], [kpathsea freetype2], [x])
- m4_include(kpse_TL[texk/xdvik/ac/xdvik.ac])
-
-thus specifying the dependency on the 'kpathsea', 'freetype', and X11
-libraries. The M4 comment (following 'dnl') signals the subsidiary
-'squeeze/configure.ac'. This is needed because the main executable
-'xdvi-bin' (to be installed as, e.g., 'xdvi-xaw') is for the 'host'
-system whereas the auxiliary program 'squeeze/squeeze' has to run on the
-'build' system and in a cross compilation they differ.
-
- The additional fragment 'ac/xdvik.ac' is also included by
-'configure.ac' and supplies the configure option '--with-xdvi-x-toolkit'
-also seen at the top-level.

-2.4.5.4 The subdirectory 'utils/asymptote'
-..........................................
-
-This subdirectory contains the sources for 'asy' and 'xasy' but due to
-its complexity and prerequisites (e.g., OpenGL) it is not part of the TL
-build system. These programs must be built and installed independently,
-but are included on the TL DVD together with their support files.

-
-2.4.6.1 Adding a new program module
-...................................
-
-A TeX-specific program module in a subdirectory 'texk/PROG' may use the
-TeX-specific libraries and is included by adding its name 'PROG' to the
-M4 list 'kpse_texk_pkgs' defined in 'm4/kpse-pkgs.m4'.
-
- A generic program module in a subdirectory 'utils/PROG' must not use
-the TeX-specific libraries and is included by adding its name 'PROG' to
-the M4 list 'kpse_utils_pkgs' in 'm4/kpse-pkgs.m4'.
-
- In either case, apart from the program sources and build system
-('configure.ac' and 'Makefile.am'), the subdirectory 'texk/PROG' or
-'utils/PROG' must provide a fragment 'ac/withenable.ac' that contains
-the M4 macro 'KPSE_ENABLE_PROG' defined in 'm4/kpse-setup.m4' with
-'PROG' as the mandatory first argument and three optional arguments:
-
- 1. a list of required libraries from the TL tree;
-
- 2. a list of options ('disable' if this module is not to be built
- without the configure option '--enable-PROG', 'native' if cross
- compilation is not possible, 'x' if the program requires X11
- libraries);
-
- 3. and a comment added to the help text for the 'configure' option
- '--enable-PROG' or '--disable-PROG'.
-
- If the module requires specific configure options to be seen at the
-top-level, they should be defined in an additional fragment 'ac/PROG.ac'
-included from 'ac/withenable.ac' and 'configure.ac'.
-
-
-File: texlive.info, Node: Adding a new generic library module, Next: Adding a new TeX-specific library module, Prev: Adding a new program module, Up: Extending TeX Live
-
-2.4.6.2 Adding a new generic library module
-...........................................
-
-A generic library module in a subdirectory 'libs/LIB' must not depend on
-TeX-specific libraries, by definition. It is included by adding its
-name 'LIB' to the M4 list 'kpse_libs_pkgs' in 'm4/kpse-pkgs.m4'--before
-any other libraries from the TeX Live tree on which it depends.
-
- As with program modules, the subdirectory 'libs/LIB' must contain the
-sources and build system for the library (and any installable support
-programs) and a fragment 'ac/withenable.ac' that contains the M4 macro
-'KPSE_WITH_LIB' defined in 'm4/kpse-setup.m4' with 'LIB' as the
-mandatory first argument and two optional arguments: a list of required
-libraries from the TL tree, and a list of options (currently there is
-only one: specify 'tree' if this library cannot be replaced by a system
-version).
-
- If a system version can be used, a second fragment 'ac/LIB.ac' is
-needed, containing the M4 macro 'KPSE_TRY_LIB' (or 'KPSE_TRY_LIBXX')
-with 'LIB' as the mandatory first argument and two additional arguments
-for the Autoconf macro 'AC_LANG_PROGRAM' used to compile and link a
-small C (or C++) program as sanity check for using the system library.
-
- In addition a file 'm4/kpse-LIB-flags' (at the top level) must define
-the M4 macro 'KPSE_LIB_FLAGS' (all uppercase) setting up the 'make'
-variables 'LIB_INCLUDES', 'LIB_LIBS', 'LIB_DEPEND', and 'LIB_RULE' with
-the values required for 'CPPFLAGS', 'LDADD', dependencies, and a
-(multi-line) 'make' rule to rebuild the library when necessary. All of
-that is needed for the library from the TL tree and, if supported, for a
-system version.
-
- If a system library is allowed, 'KPSE_LIB_FLAGS' also provides the
-configure option '--with-system-LIB' and uses the additional M4 macro
-'KPSE_LIB_SYSTEM_FLAGS' to generate the 'make' variables for a system
-library. Furthermore the definition of the M4 macro
-'KPSE_ALL_SYSTEM_FLAGS' in 'm4/kpse-pkgs.m4' must be extended by the
-line:
- 'AC_REQUIRE([KPSE_LIB_SYSTEM_FLAGS])'

-................................................
-
-A TeX-specific library module in a subdirectory 'texk/LIB' may depend on
-other TeX-specific libraries but must not depend on any generic library
-from the TL tree. It is included in the same general ways as a generic
-library (see the previous section), with these modifications:
-
- * The library name 'LIB' is added to the M4 list 'kpse_texlibs_pkgs'

-2.5 Configure options
-=====================
-
-Corresponding to the large number of program and library modules there
-are a large number 'configure' options, most of which are described
-here. The command
- 'configure --help'
-at the top level gives an exhaustive list of all global options and a
-few important module-specific ones, whereas, e.g.,
- 'texk/lcdf-typetools/configure --help'
-also displays the 'lcdf-typetools' specific options, which are not shown
-by the top-level '--help'.
-
- The help text also mentions several influential environment
-variables, but for TeX Live it is better to specify them as assigments
-on the command line.
-
- The './Build' script used to make the binaries shipped with TeX Live
-invokes the top-level 'configure' with a few additional options (*note
-Building::). The defaults discussed below are those for the actual
-'configure' script; invoking 'configure' via './Build' may yield
-different results.
-
- Defaults for most options are set at the top level and propagated
-explicitly to all subdirectories. Options specified on the command line
-are checked for consistency but never modified.

-........................................
-
-If enabled (the default), build for a TL binary distribution as shipped
-by the TeX user groups. This requires GNU 'make' and implies
-'--enable-multiplatform' and '--enable-cxx-runtime-hack' (unless they
-are explicitly disabled), and enforces '--disable-shared'.
-
- If building TL for a GNU/Linux or other distribution, this should be
-disabled and system versions of most libraries would be used (*note
-Distro builds::). This may fail without GNU 'make', but will be tried
-regardless.
-
- A related option, '--enable-texlive-build', is automatically passed
-to all subdirectories (and cannot be disabled). Subdirectories that can
-also be built independently from the TL tree (such as 'utils/xindy' and
-'texk/dvipng') can use this option, e.g., to choose TL-specific
-installation paths.

-
- With LFS, there is no fixed limit on the size of PDF files created by

-
-'--with-banner-add=STR'
-Add 'STR' to the default version string ('TeX Live YEAR' or 'Web2C
-YEAR') appended to banner lines. This is ignored for a native TL build,
-but distro builds should specify, e.g., '/SOMEDISTRO'.
-
-'--with-editor=CMD'
-Specify the command 'CMD' to invoke from the 'e' option of TeX-like

---position=%d "%s"' for Windows.
-
-'--with-fontconfig-includes=DIR', '--with-fontconfig-libdir=DIR'
-Building XeTeX on non-Mac systems requires the 'fontconfig' library
-headers and code. If one or both of these options are given, the
-required flags are derived from them; otherwise, they are determined via
-'pkg-config' (if present).
-
-'--with-mf-x-toolkit'
-Use the X toolkit ('libXt') for Metafont (the default is to use the
-lowest-level 'Xlib' support; it seems this has the best chance of
-working across X installations nowadays).
-
-'--disable-dump-share'
-Make the 'fmt'/'base' dump files architecture dependent (somewhat faster
-on LittleEndian architectures).
-
-'--disable-ipc'
-Disable TeX's '--ipc' option.
-
-'--disable-mf-nowin'
-Do not build a separate non-graphically-capable Metafont ('mf-nowin').
-
-'--disable-omfonts'
-Build the WEB versions of the Omega font utilities 'ofm2opl', 'opl2ofm',
-'ovf2ovp', and 'ovp2ovf' instead of the C version 'omfonts'. The WEB
-and C versions should be roughly equivalent.
-

-
-'--enable-auto-core'
-This option causes TeX and Metafont to produce a core dump when a
-particular hacky filename is encountered, for use in creating preloaded
-binaries. This is rarely done nowadays.
-
-'--enable-libtool-hack'
-If enabled (which is the default for all platforms), prevents 'libtool'
-from linking explicitly with dependencies of 'libfontconfig' such as
-'libexpat'.

------------------------------
-
-The values for these variables can be specified as 'configure' arguments
-of the form 'VAR=VALUE'. They can also be defined in the environment,
-but that might not work for cross compilations.
-
-'CC'
-'CXX'
-'CPPFLAGS'
- And plenty more. As usual with Autoconf, these variables specify
- the name (or full path) of compilers, preprocessor flags, and
- similar. *Note autoconf: (GNU Autoconf)Preset Output Variables.
-
-'CLISP'
- Name (or full path) of the 'clisp' executable, used to build
- 'xindy'.
-
-'FT2_CONFIG'
-'ICU_CONFIG'
-'PKG_CONFIG'
- These specify the name (or path) for the 'freetype-config',
- 'icu-config', and 'pkg-config' commands used to determine the flags
- required for system versions of 'libfreetype', the ICU libraries,
- or many other libraries.
-
-'KPSEWHICH'
- Name (or path) of an installed 'kpsewhich' binary, used by 'make
- check' to determine the location of, e.g., 'cmbx10.tfm'.
-
-'MAKE'
-'SED'
- And more. Name (or path) of the 'make', 'sed', and similar
- programs; used at the top level and propagated to all
- subdirectories.
-
-'PERL'
-'LATEX'
-'PDFLATEX'
- Name (or full path) for the 'perl', 'latex', and 'pdflatex'
- commands used, e.g., to build the 'xindy' documentation.
-
-'TL_PLATFORM'
- The utility program 'biber' consists of many Perl modules bundled
- into an executable by the 'Par::Packer' mechanism. Therefore it is
- not feasible to build 'biber' as part of TL.
-
- However, in order for 'make install' to create all executables in
- 'bindir', the 'biber' module in TL contains pre-made binaries (by
- 'biber' contributors, released on the original 'biber' site) for
- the platforms for which they are available. TL merely checks if an
- executable is present for the current platform, and if so, installs
- it.
-
- The complication is hidden in the phrase "current platform". TL
- has its own ideas about platform names, and the mapping from the
- canonical system name determined by 'config.guess' or 'config.sub'
- to the TL platform name is not trivial. So, a value given for
- 'TL_PLATFORM' is used as the TL platform name. Otherwise, the
- build uses copies of the Perl modules 'TeXLive/TLUtils.pm' and
- 'TeXLive/TLConfig.pm', to avoid duplicating the platform-detection
- logic.

-
-2.6 Cross compilation
-=====================
-
-In a cross compilation a "build" system is used to create binaries to be
-executed on a "host" system with different hardware and/or operating
-system.
-
- In simple cases, the build system can execute binaries for the host
-system. This typically occurs for bi-arch systems where, e.g.,
-'i386-linux' binaries can run on 'x86_64-linux' systems and 'win32'
-binaries can run on 'win64' systems. Although sometimes called "native
-cross", technically this is not cross compilation at all. In most such
-cases it suffices to specify suitable compiler flags. It might be
-useful to add the configure option '--build=HOST' to get the correct
-canonical host name, but note that this should _not_ be '--host=HOST'
-(*note (autoconf)Hosts and Cross-Compilation::).
-
- In order to build, e.g., 32-bit binaries with 'clang' on a 64-bit OSX
-system one could use
- './Build --build=i386-apple-darwin CC='clang -arch i386'' \
- 'CXX='clang++ -arch i386' OBJCXX='clang++ -arch i386''

-
-2.6.1 Cross configuring
------------------------
-
-In a standard cross compilation, binaries for the host system cannot
-execute on the build system and it is necessary to specify the configure
-options '--host=HOST' and '--build=BUILD' with two different values.
-
- Building binaries requires suitable "cross" tools, e.g., compiler,
-linker, and archiver, and perhaps a "cross" version of 'pkg-config' and
-similar to locate host system libraries. Autoconf expects that these
-cross tools are given by their usual variables or found under their
-usual name prefixed with 'HOST-'. Here a list of such tools and
-corresponding variables:
-
- ar AR
- freetype-config FT2_CONFIG
- g++ CXX
- gcc CC
- icu-config ICU_CONFIG
- objdump OBJDUMP
- pkg-config PKG_CONFIG
- ranlib RANLIB
- strip STRIP
-
-In order to, e.g., build 'mingw32' binaries on 'x86_64-linux' with a
-cross compiler found as 'i386-pc-mingw32-gcc' one would specify
-
- --host=i386-pc-mingw32 --build=x86_64-linux-gnu
-
-or perhaps
-
- --host=mingw32 --build=x86_64-linux CC=i386-pc-mingw32-gcc
-
-but this latter, especially, might require adding 'CXX' and others.
-
- Configure arguments such as 'CFLAGS=...' refer to the cross compiler.
-If necessary, you can specify compilers and flags for the few auxiliary
-C and C++ programs required for the build process as configure arguments
-
- BUILDCC=...
- BUILDCPPFLAGS=...
- BUILDCFLAGS=...
- BUILDCXX=...

-File: texlive.info, Node: Cross problems, Prev: Cross configuring, Up: Cross compilation
-
-2.6.2 Cross problems
---------------------
-
-The fact that binaries for the host system cannot be executed on the
-build system causes some problems.
-
- One problem is that configure tests using 'AC_RUN_IFELSE' can compile
-and link the test program but cannot execute it. Such tests should be
-avoided if possible and otherwise must supply a pessimistic test result.
-
- Another problem arises if the build process must execute some
-(auxiliary or installable) programs. Auxiliary programs can be placed
-into a subdirectory that is configured natively as is done for
-'texk/web2c/web2c', 'texk/dvipsk/squeeze', and 'texk/xdvik/squeeze'.
-The module 'libs/freetype' uses the value of 'CC_BUILD', 'BUILD-gcc',
-'gcc', or 'cc' as compiler for the auxiliary program.
-
- The situation for installable programs needed by the build process is
-somewhat different. A quite expensive possibility, chosen for the ICU
-libraries in module 'libs/icu', is to first compile natively for the
-build system and in a second step to use these (uninstalled) programs
-during the cross compilation.
-
- This approach would also be possible for the tools such as 'tangle'
-used in the module 'texk/web2c' to build the WEB programs, but that
-would require first building a native 'kpathsea' library. To avoid this
-complication, cross compilation of the WEB or CWEB programs requires
-sufficiently recent installed versions of 'tangle', 'ctangle',
-'otangle', and 'tie'.
-
- Building 'xindy' requires running the host system 'clisp' binary,
-thus cross compilation is not possible.
-

-
-2.7 Coding conventions
-======================
-
-Ideally, building all of TeX Live with '--enable-compiler-warnings=max'
-should produce no (GCC) compiler warnings at all. In spite of
-considerable efforts into that direction we are still far from that goal
-and there are reasons that we may never fully reach it. Below are some
-rules about declarations of functions or variables and the use of
-'const'. These rules should be applied to all parts of the TeX Live
-tree, except some of those maintained independently.
-
-* Menu:
-
-* Declarations and definitions::
-* Const::
-
-
-File: texlive.info, Node: Declarations and definitions, Next: Const, Up: Coding conventions
-
-2.7.1 Declarations and definitions
-----------------------------------
-
-C standards
-...........
-
-The TeX Live build system no longer supports pre-ANSI C compilers. Thus
-all function prototypes and definitions must conform to the ANSI C
-standard (including 'void' in the declaration of C functions with no
-parameters). On the other hand, TL is built for a wide variety of
-systems, not all of which support the C99 standard. Therefore using C99
-features should be avoided if that can easily be done. In particular C
-code must not contain declarations after statements or C++-style
-comments.
-
- If some C99 (or later) constructs must be used, the module should
-verify that they are available and otherwise provide an alternative.
-For example, the module 'texk/chktex' uses the C99 function 'stpcpy()'
-that may or may not be available on a particular system. It uses
-'AC_CHECK_DECLS([stpcpy])' in 'configure.ac' to test this, and provides
-the perhaps slightly less efficient alternative
-
- #if !(defined HAVE_DECL_STPCPY && HAVE_DECL_STPCPY)
- #static inline char *stpcpy(char *dest, const char *src)
- {
- return strcpy(dest, src) + strlen(src);
- }
- #endif
-
-in the file 'Utility.h'.
-
-Static functions
-................
-
-Functions used in only one file should be declared 'static'; they
-require no prototype except as forward declaration.
-
-Extern functions
-................
-
-Functions not declared 'static', usually because they are used in
-several files, require an ('extern') prototype in exactly one header
-file, which is included in the file defining the function and in all
-files using that function--this is the only way to guarantee consistency
-between definition and use. There should be no 'extern' declarations
-sprinkled throughout the C code (with or without comments as to where
-that function is defined).
-
-Variable declarations
-.....................
-
-The declaration of global variables follows analogous rules: they are
-either declared 'static' if used in only one file or declared 'extern'
-in exactly one header and instantiated in exactly one file.
-
-
-File: texlive.info, Node: Const, Prev: Declarations and definitions, Up: Coding conventions
-
-2.7.2 Const
------------
-
-The 'const' feature of C is valuable, but easy to mis-use.
-
-Function parameters
-...................
-
-Ideally, a function parameter not modified by the function should be
-declared as 'const'. This is important in particular for strings
-('char*') because the actual arguments are often string literals. It is
-perfectly legitimate and safe to use a type 'char*' value for a type
-'const char*' variable (in an assignment, as initializer, as function
-argument, or as return value). It is equally safe to use a type
-'char**' value for a type 'const char*const*' variable, but not for a
-type 'const char**' variable since that might cause modification of a
-quantity supposed to be constant.
-
- Getting all 'const' qualifiers right can get quite involved but can
-almost always be done. There are only a couple notable exceptions: the
-X11 headers are full of declarations that ought to use 'const' but do
-not, and the same is true to some extent for 'libfreetype' (but,
-thankfully, not for 'zlib' nowadays).
-
-What must be avoided with 'const'
-.................................
-
-The GCC compiler warnings "assignment discards qualifiers..." and
-analogous warnings for "initialization", "passing arg", or "return" must
-be strenously avoided in our own code. The only exception is when they
-are caused by X11 headers or macros or other third party code.
-
-What should be avoided with 'const'
-...................................
-
-A type cast, e.g., from 'const char*' to 'char*' does not solve any
-problems; depending on warning options, it may only hide them.
-Therefore such casts should be avoided whenever possible and otherwise
-must be carefully analyzed to make sure that they cannot cause the
-modification of quantities supposed to be constant.
