NOTES ON BUILDING TLPERL 2012 November update

BUILD PLATFORM

32-bits Windows 7 SP1 running under VirtualBox on
Linux.

GETTING THE PERL SOURCE

Release version:
I downloaded from CPAN: the latest stable Perl source 5.18.2

THE COMPILER

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, the latter one also being packaged with Strawberry
Perl. I used this bundled mingw, but not the rest on SP. It includes
dmake.

BUILDING

I went to the win32 subdirectory of the Perl source. In makefile.mk
I adjusted relevant settings to my build environment. As in the
previous release, I turned off optimization to avoid some
intractable failures. In addition, to avoid some errors while
running the test suite, I applied a patch which I found at
https://github.com/Alexpux/MINGW-packages/blob/master/mingw-w64-perl/perl-5.18.0-add-missing-mingw-libs.patch

  test : test-prep
[end of patch]

I compiled with

  dmake

and installed with

  dmake installbare

`installbare' omits the generation of html.

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 particular the
single-quoted here-documents with markers !END! (very long) and
EOVIRTUAL.

The original versions are still present under the names Config.pm.orig
and Config_heavy.pl.orig.

When adding modules, I added the new Perl bin directory to the
searchpath. I downloaded all the modules from CPAN and added them with

  perl Makefile.PL
  dmake
  dmake install

They are, in order of processing:

  Math-Int64-0.30.tar.gz

Windows-specific:

  Win32-API-0.77.tar.gz
  Win32API-Registry-0.32.tar.gz
  Win32-TieRegistry-0.26.tar.gz
  Win32-Shortcut-0.08.tar.gz
  Win32-Process-Info-1.020.tar.gz
  Win32-OLE-0.1711.tar.gz - warnings

Perl/Tk:

  Tk-804.032.tar.gz

This module did not compile rightaway: an entry '-limm32' somehow
did not make it into LDLOADLIBS in the generated makefile. After
manually adding this at the end of the definition, the module
compiled.

  Tk-DirSelect-1.12.tar.gz

LWP and dependencies, in order of compilation/installation:

  HTML-Tagset-3.20.tar.gz
  HTML-Parser-3.71.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
  IO-HTML-1.00.tar.gz
  HTTP-Message-6.06.tar.gz
  HTTP-Cookies-6.01.tar.gz
  HTTP-Daemon-6.01.tar.gz
  HTTP-Negotiate-6.01.tar.gz
  Net-HTTP-6.06.tar.gz
  WWW-RobotRules-6.02.tar.gz
  LWP-Protocol-https-6.06.tar.gz
  libwww-perl-6.06.tar.gz

Other:

  IO-String-1.08.tar.gz
  Digest-SHA1-2.13.tar.gz (for 3rd-party scripts)

MODIFICATIONS FOR TEXLIVE

- as explained above: our versions of lib/Config.pm and lib/Config_heavy.pl
  compute the location of tlperl dynamically.
- 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_sjlj_1.dll, libstdc++-6.dll, libpng16-16_.dll and.

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.

Both tests with 32-bits Windows XP Enterprise as regular user and
64-bits Windows 7 Professional as admin user.

These tests do not require a for perl updated texlive.tlpdb.

tlmgr appeared to work as intended.  I also successfully ran
the uninstaller.
