NOTES ON BUILDING TLPERL 2012 November update
BUILD PLATFORM
32-bits Windows XP Professional SP3 running under VirtualBox on
Linux. The user is not an administrator.
GETTING THE PERL SOURCE
Release version:
I downloaded from CPAN: the latest stable Perl source 5.16.2
COLLECTING A NATIVE BUILD ENVIRONMENT
I found in the root of the distribution a file README.win32
containing compilation instructions, which listed both mingw32 from
mingw.org and the newer mingw64 from mingw-w64.sf.net as possible
compilers.
I downloaded and ran the automated downloader/installer
x86-mingw32-build-1.0-sh.tar.bz2. I selected gcc and g++. I added
the mingw32 bin subdirectory to the searchpath.
Based on the same README.win32 from the Perl source, I downloaded
dmake-4.12-2009-SHAY.zip from
http://search.cpan.org/dist/dmake. Following the file readme.txt in
the root of this archive, I added the file dmake.exe and the startup
subdirectory to the bin subdirectory of mingw.
BUILDING
I went to the win32 subdirectory of the Perl source. In makefile.mk I
adjusted relevant settings to my build environment. Hoping to avoid
some intractable failures I turned off optimization:
*** makefile.mk.orig 2012-10-26 05:07:28.000000000 +0200
--- makefile.mk 2012-11-16 17:50:27.947856481 +0100
*** 428,434 ****
OPTIMIZE = -g -O2 -DDEBUGGING
LINK_DBG = -g
.ELSE
! OPTIMIZE = -s -O2
LINK_DBG = -s
.ENDIF
--- 428,434 ----
OPTIMIZE = -g -O2 -DDEBUGGING
LINK_DBG = -g
.ELSE
! OPTIMIZE = -s -O0
LINK_DBG = -s
.ENDIF
Then I typed
dmake
and
dmake install
There were hard-coded paths in lib/Config.pm and
lib/Config_heavy.pl, which were likely to cause problems.
I edited lib/Config.pm and lib/Config_heavy.pl to compute Perl's
location dynamically. To both I add the code
my $rootdir = __FILE__;
$rootdir =~ s![\\/][^\\/]*[\\/][^\\/]*$!!;
$rootdir =~ s!/!\\!g;
and used this in Config.pm for the definition of %Config, taking
care to replace single-quoted strings with double-quoted ones and
escaping backslashes and other characters where necessary. I also
parameterized the location of the mingw compiler.
Config_heavy.pl got a similar treatment: in single-quoted
here-documents with markers !END! (very long) and EOVIRTUAL I
replaced the hard-coded Perl paths. Because the $rootdir variable
needed to be interpolated, I shifted from single- to double-quoting,
which required escaping various characters.
The original versions are still present under the names Config.pm.orig
and Config_heavy.pl.orig. Diffs are here.
For adding modules, I added the new Perl bin directory to the
searchpath. I downloaded them all from CPAN.
Windows-specific:
Win32-API-0.68.tar.gz
Win32-Shortcut-0.07.tar.gz
Win32API-Registry-0.32.tar.gz
Win32-TieRegistry-0.26.tar.gz
Win32-Process-Info-1.019.tar.gz
Perl/Tk:
Tk-804.030.tar.gz
LWP and dependencies, in order of compilation/installation:
HTML-Tagset-3.20.tar.gz
HTML-Parser-3.69.tar.gz
URI-1.60.tar.gz
Encode-Locale-1.03.tar.gz
HTTP-Date-6.02.tar.gz
File-Listing-6.04.tar.gz
LWP-MediaTypes-6.02.tar.gz
HTTP-Message-6.03.tar.gz
HTTP-Cookies-6.01.tar.gz
HTTP-Daemon-6.01.tar.gz
HTTP-Negotiate-6.01.tar.gz
Net-HTTP-6.03.tar.gz
WWW-RobotRules-6.02.tar.gz
libwww-perl-6.04.tar.gz
Other:
IO-String-1.08.tar.gz
Digest-SHA1-2.13.tar.gz (for 3rd-party scripts)
They were all configured, compiled and installed with
perl Makefile.PL
dmake
dmake install
Compared to 2011, two modules have been dropped because of
additional dependencies:
Carp-Always-0.11 (for backtracing)
File-Which-1.09 (for a 3rd-party script)
MODIFICATIONS FOR TEXLIVE
- lib/Config.pm and lib/Config_heavy.pl now compute the location of
tlperl dynamically; see above.
- The html directory has been removed.
- The site/lib subdirectory is folded into lib.
- The bin subdirectory now only contains exe- and dll files;
Batch files and Perl scripts have been removed.
- Copied from mingw/bin to tlperl/bin:
libgcc_s_dw2_1.dll and libstdc++-6.dll.
TESTING WITH TEXLIVE
For testing the new Perl with the installer, I unpacked the net
installer and replaced its tlperl with the new one.
For testing the new Perl with the installed TeX Live, I copied it
into the fresh installation.
tlmgr appeared to work as intended. I also successfully ran
the uninstaller.
