-=head1 NAME
-
-perlcygwin - Perl for Cygwin
-
-=head1 SYNOPSIS
-
-This document will help you configure, make, test and install Perl
-on Cygwin. This document also describes features of Cygwin that will
-affect how Perl behaves at runtime.
-
-B<NOTE:> There are pre-built Perl packages available for Cygwin and a
-version of Perl is provided in the normal Cygwin install. If you do
-not need to customize the configuration, consider using one of those
-packages.
-
-
-=head1 PREREQUISITES FOR COMPILING PERL ON CYGWIN
-
-=head2 Cygwin = GNU+Cygnus+Windows (Don't leave UNIX without it)
-
-The Cygwin tools are ports of the popular GNU development tools for Win32
-platforms. They run thanks to the Cygwin library which provides the UNIX
-system calls and environment these programs expect. More information
-about this project can be found at:
-
-L<http://www.cygwin.com/>
-
-A recent net or commercial release of Cygwin is required.
-
-At the time this document was last updated, Cygwin 1.7.10 was current.
-
-
-=head2 Cygwin Configuration
-
-While building Perl some changes may be necessary to your Cygwin setup so
-that Perl builds cleanly. These changes are B<not> required for normal
-Perl usage.
-
-B<NOTE:> The binaries that are built will run on all Win32 versions.
-They do not depend on your host system (WinXP/Win2K/Win7) or your
-Cygwin configuration (binary/text mounts, cvgserver).
-The only dependencies come from hard-coded pathnames like C</usr/local>.
-However, your host system and Cygwin configuration will affect Perl's
-runtime behavior (see L</"TEST">).
-
-=over 4
-
-=item * C<PATH>
-
-Set the C<PATH> environment variable so that Configure finds the Cygwin
-versions of programs. Any not-needed Windows directories should be removed or
-moved to the end of your C<PATH>.
-
-=item * I<nroff>
-
-If you do not have I<nroff> (which is part of the I<groff> package),
-Configure will B<not> prompt you to install I<man> pages.
-
-=back
-
-=head1 CONFIGURE PERL ON CYGWIN
-
-The default options gathered by Configure with the assistance of
-F<hints/cygwin.sh> will build a Perl that supports dynamic loading
-(which requires a shared F<cygperl5_16.dll>).
-
-This will run Configure and keep a record:
-
- ./Configure 2>&1 | tee log.configure
-
-If you are willing to accept all the defaults run Configure with B<-de>.
-However, several useful customizations are available.
-
-=head2 Stripping Perl Binaries on Cygwin
-
-It is possible to strip the EXEs and DLLs created by the build process.
-The resulting binaries will be significantly smaller. If you want the
-binaries to be stripped, you can either add a B<-s> option when Configure
-prompts you,
-
- Any additional ld flags (NOT including libraries)? [none] -s
- Any special flags to pass to g++ to create a dynamically loaded library?
- [none] -s
- Any special flags to pass to gcc to use dynamic linking? [none] -s
-
-or you can edit F<hints/cygwin.sh> and uncomment the relevant variables
-near the end of the file.
-
-=head2 Optional Libraries for Perl on Cygwin
-
-Several Perl functions and modules depend on the existence of
-some optional libraries. Configure will find them if they are
-installed in one of the directories listed as being used for library
-searches. Pre-built packages for most of these are available from
-the Cygwin installer.
-
-=over 4
-
-=item * C<-lcrypt>
-
-The crypt package distributed with Cygwin is a Linux compatible 56-bit
-DES crypt port by Corinna Vinschen.
-
-Alternatively, the crypt libraries in GNU libc have been ported to Cygwin.
-
-=item * C<-lgdbm_compat> (C<use GDBM_File>)
-
-GDBM is available for Cygwin.
-
-NOTE: The GDBM library only works on NTFS partitions.
-
-=item * C<-ldb> (C<use DB_File>)
-
-BerkeleyDB is available for Cygwin.
-
-NOTE: The BerkeleyDB library only completely works on NTFS partitions.
-
-=item * C<cygserver> (C<use IPC::SysV>)
-
-A port of SysV IPC is available for Cygwin.
-
-NOTE: This has B<not> been extensively tested. In particular,
-C<d_semctl_semun> is undefined because it fails a Configure test
-and on Win9x the I<shm*()> functions seem to hang. It also creates
-a compile time dependency because F<perl.h> includes F<<sys/ipc.h>>
-and F<<sys/sem.h>> (which will be required in the future when compiling
-CPAN modules). CURRENTLY NOT SUPPORTED!
-
-=item * C<-lutil>
-
-Included with the standard Cygwin netrelease is the inetutils package
-which includes libutil.a.
-
-=back
-
-=head2 Configure-time Options for Perl on Cygwin
-
-The F<INSTALL> document describes several Configure-time options. Some of
-these will work with Cygwin, others are not yet possible. Also, some of
-these are experimental. You can either select an option when Configure
-prompts you or you can define (undefine) symbols on the command line.
-
-=over 4
-
-=item * C<-Uusedl>
-
-Undefining this symbol forces Perl to be compiled statically.
-
-=item * C<-Dusemymalloc>
-
-By default Perl does not use the C<malloc()> included with the Perl source,
-because it was slower and not entirely thread-safe. If you want to force
-Perl to build with the old -Dusemymalloc define this.
-
-=item * C<-Uuseperlio>
-
-Undefining this symbol disables the PerlIO abstraction. PerlIO is now the
-default; it is not recommended to disable PerlIO.
-
-=item * C<-Dusemultiplicity>
-
-Multiplicity is required when embedding Perl in a C program and using
-more than one interpreter instance. This is only required when you build
-a not-threaded perl with C<-Uuseithreads>.
-
-=item * C<-Uuse64bitint>
-
-By default Perl uses 64 bit integers. If you want to use smaller 32 bit
-integers, define this symbol.
-
-=item * C<-Duselongdouble>
-
-I<gcc> supports long doubles (12 bytes). However, several additional
-long double math functions are necessary to use them within Perl
-(I<{atan2, cos, exp, floor, fmod, frexp, isnan, log, modf, pow, sin, sqrt}l,
-strtold>).
-These are B<not> yet available with newlib, the Cygwin libc.
-
-=item * C<-Uuseithreads>
-
-Define this symbol if you want not-threaded faster perl.
-
-=item * C<-Duselargefiles>
-
-Cygwin uses 64-bit integers for internal size and position calculations,
-this will be correctly detected and defined by Configure.
-
-=item * C<-Dmksymlinks>
-
-Use this to build perl outside of the source tree. Details can be
-found in the F<INSTALL> document. This is the recommended way to
-build perl from sources.
-
-=back
-
-=head2 Suspicious Warnings on Cygwin
-
-You may see some messages during Configure that seem suspicious.
-
-=over 4
-
-=item * Win9x and C<d_eofnblk>
-
-Win9x does not correctly report C<EOF> with a non-blocking read on a
-closed pipe. You will see the following messages:
-
- But it also returns -1 to signal EOF, so be careful!
- WARNING: you can't distinguish between EOF and no data!
-
- *** WHOA THERE!!! ***
- The recommended value for $d_eofnblk on this machine was "define"!
- Keep the recommended value? [y]
-
-At least for consistency with WinNT, you should keep the recommended
-value.
-
-=item * Compiler/Preprocessor defines
-
-The following error occurs because of the Cygwin C<#define> of
-C<_LONG_DOUBLE>:
-
- Guessing which symbols your C compiler and preprocessor define...
- try.c:<line#>: missing binary operator
-
-This failure does not seem to cause any problems. With older gcc
-versions, "parse error" is reported instead of "missing binary
-operator".
-
-=back
-
-=head1 MAKE ON CYGWIN
-
-Simply run I<make> and wait:
-
- make 2>&1 | tee log.make
-
-=head1 TEST ON CYGWIN
-
-There are two steps to running the test suite:
-
- make test 2>&1 | tee log.make-test
-
- cd t; ./perl harness 2>&1 | tee ../log.harness
-
-The same tests are run both times, but more information is provided when
-running as C<./perl harness>.
-
-Test results vary depending on your host system and your Cygwin
-configuration. If a test can pass in some Cygwin setup, it is always
-attempted and explainable test failures are documented. It is possible
-for Perl to pass all the tests, but it is more likely that some tests
-will fail for one of the reasons listed below.
-
-=head2 File Permissions on Cygwin
-
-UNIX file permissions are based on sets of mode bits for
-{read,write,execute} for each {user,group,other}. By default Cygwin
-only tracks the Win32 read-only attribute represented as the UNIX file
-user write bit (files are always readable, files are executable if they
-have a F<.{com,bat,exe}> extension or begin with C<#!>, directories are
-always readable and executable). On WinNT with the I<ntea> C<CYGWIN>
-setting, the additional mode bits are stored as extended file attributes.
-On WinNT with the default I<ntsec> C<CYGWIN> setting, permissions use the
-standard WinNT security descriptors and access control lists. Without one of
-these options, these tests will fail (listing not updated yet):
-
- Failed Test List of failed
- ------------------------------------
- io/fs.t 5, 7, 9-10
- lib/anydbm.t 2
- lib/db-btree.t 20
- lib/db-hash.t 16
- lib/db-recno.t 18
- lib/gdbm.t 2
- lib/ndbm.t 2
- lib/odbm.t 2
- lib/sdbm.t 2
- op/stat.t 9, 20 (.tmp not an executable extension)
-
-=head2 NDBM_File and ODBM_File do not work on FAT filesystems
-
-Do not use NDBM_File or ODBM_File on FAT filesystem. They can be
-built on a FAT filesystem, but many tests will fail:
-
- ../ext/NDBM_File/ndbm.t 13 3328 71 59 83.10% 1-2 4 16-71
- ../ext/ODBM_File/odbm.t 255 65280 ?? ?? % ??
- ../lib/AnyDBM_File.t 2 512 12 2 16.67% 1 4
- ../lib/Memoize/t/errors.t 0 139 11 5 45.45% 7-11
- ../lib/Memoize/t/tie_ndbm.t 13 3328 4 4 100.00% 1-4
- run/fresh_perl.t 97 1 1.03% 91
-
-If you intend to run only on FAT (or if using AnyDBM_File on FAT),
-run Configure with the -Ui_ndbm and -Ui_dbm options to prevent
-NDBM_File and ODBM_File being built.
-
-With NTFS (and no CYGWIN=nontsec), there should be no problems even if
-perl was built on FAT.
-
-=head2 C<fork()> failures in io_* tests
-
-A C<fork()> failure may result in the following tests failing:
-
- ext/IO/lib/IO/t/io_multihomed.t
- ext/IO/lib/IO/t/io_sock.t
- ext/IO/lib/IO/t/io_unix.t
-
-See comment on fork in L</Miscellaneous> below.
-
-=head1 Specific features of the Cygwin port
-
-=head2 Script Portability on Cygwin
-
-Cygwin does an outstanding job of providing UNIX-like semantics on top of
-Win32 systems. However, in addition to the items noted above, there are
-some differences that you should know about. This is a very brief guide
-to portability, more information can be found in the Cygwin documentation.
-
-=over 4
-
-=item * Pathnames
-
-Cygwin pathnames are separated by forward (F</>) slashes, Universal
-Naming Codes (F<//UNC>) are also supported Since cygwin-1.7 non-POSIX
-pathnames are disencouraged. Names may contain all printable
-characters.
-
-File names are case insensitive, but case preserving. A pathname that
-contains a backslash or drive letter is a Win32 pathname, and not
-subject to the translations applied to POSIX style pathnames, but
-cygwin will warn you, so better convert them to POSIX.
-
-For conversion we have C<Cygwin::win_to_posix_path()> and
-C<Cygwin::posix_to_win_path()>.
-
-Since cygwin-1.7 pathnames are UTF-8 encoded.
-
-=item * Text/Binary
-
-Since cywgin-1.7 textmounts are deprecated and stronlgy discouraged.
-
-When a file is opened it is in either text or binary mode. In text mode
-a file is subject to CR/LF/Ctrl-Z translations. With Cygwin, the default
-mode for an C<open()> is determined by the mode of the mount that underlies
-the file. See L</Cygwin::is_binmount>(). Perl provides a C<binmode()> function
-to set binary mode on files that otherwise would be treated as text.
-C<sysopen()> with the C<O_TEXT> flag sets text mode on files that otherwise
-would be treated as binary:
-
- sysopen(FOO, "bar", O_WRONLY|O_CREAT|O_TEXT)
-
-C<lseek()>, C<tell()> and C<sysseek()> only work with files opened in binary
-mode.
-
-The text/binary issue is covered at length in the Cygwin documentation.
-
-=item * PerlIO
-
-PerlIO overrides the default Cygwin Text/Binary behaviour. A file will
-always be treated as binary, regardless of the mode of the mount it lives
-on, just like it is in UNIX. So CR/LF translation needs to be requested in
-either the C<open()> call like this:
-
- open(FH, ">:crlf", "out.txt");
-
-which will do conversion from LF to CR/LF on the output, or in the
-environment settings (add this to your .bashrc):
-
- export PERLIO=crlf
-
-which will pull in the crlf PerlIO layer which does LF -> CRLF conversion
-on every output generated by perl.
-
-=item * F<.exe>
-
-The Cygwin C<stat()>, C<lstat()> and C<readlink()> functions make the F<.exe>
-extension transparent by looking for F<foo.exe> when you ask for F<foo>
-(unless a F<foo> also exists). Cygwin does not require a F<.exe>
-extension, but I<gcc> adds it automatically when building a program.
-However, when accessing an executable as a normal file (e.g., I<cp>
-in a makefile) the F<.exe> is not transparent. The I<install> program
-included with Cygwin automatically appends a F<.exe> when necessary.
-
-=item * Cygwin vs. Windows process ids
-
-Cygwin processes have their own pid, which is different from the
-underlying windows pid. Most posix compliant Proc functions expect
-the cygwin pid, but several Win32::Process functions expect the
-winpid. E.g. C<$$> is the cygwin pid of F</usr/bin/perl>, which is not
-the winpid. Use C<Cygwin::winpid_to_pid()> and C<Cygwin::winpid_to_pid()>
-to translate between them.
-
-=item * Cygwin vs. Windows errors
-
-Under Cygwin, $^E is the same as $!. When using L<Win32 API Functions|Win32>,
-use C<Win32::GetLastError()> to get the last Windows error.
-
-=item * rebase errors on fork or system
-
-Using C<fork()> or C<system()> out to another perl after loading multiple dlls
-may result on a DLL baseaddress conflict. The internal cygwin error
-looks like like the following:
-
- 0 [main] perl 8916 child_info_fork::abort: data segment start: parent
- (0xC1A000) != child(0xA6A000)
-
-or:
-
- 183 [main] perl 3588 C:\cygwin\bin\perl.exe: *** fatal error - unable to remap C:\cygwin\bin\cygsvn_subr-1-0.dll to same address as parent(0x6FB30000) != 0x6FE60000
- 46 [main] perl 3488 fork: child 3588 - died waiting for dll loading, errno11
-
-See L<http://cygwin.com/faq/faq-nochunks.html#faq.using.fixing-fork-failures>
-It helps if not too many DLLs are loaded in memory so the available address space is larger,
-e.g. stopping the MS Internet Explorer might help.
-
-Use the perlrebase or rebase utilities to resolve the conflicting dll addresses.
-The rebase package is included in the Cygwin setup. Use F<setup.exe>
-from L<http://www.cygwin.com/setup.exe> to install it.
-
-1. kill all perl processes and run C<perlrebase> or
-
-2. kill all cygwin processes and services, start dash from cmd.exe and run C<rebaseall>.
-
-=item * C<chown()>
-
-On WinNT C<chown()> can change a file's user and group IDs. On Win9x C<chown()>
-is a no-op, although this is appropriate since there is no security model.
-
-=item * Miscellaneous
-
-File locking using the C<F_GETLK> command to C<fcntl()> is a stub that
-returns C<ENOSYS>.
-
-Win9x can not C<rename()> an open file (although WinNT can).
-
-The Cygwin C<chroot()> implementation has holes (it can not restrict file
-access by native Win32 programs).
-
-Inplace editing C<perl -i> of files doesn't work without doing a backup
-of the file being edited C<perl -i.bak> because of windowish restrictions,
-therefore Perl adds the suffix C<.bak> automatically if you use C<perl -i>
-without specifying a backup extension.

-=head1 BUGS ON CYGWIN
-
-Support for swapping real and effective user and group IDs is incomplete.
-On WinNT Cygwin provides C<setuid()>, C<seteuid()>, C<setgid()> and C<setegid()>.
-However, additional Cygwin calls for manipulating WinNT access tokens
-and security contexts are required.
