NOTES ON BUILDING TLPERL 2020
BUILD PLATFORM
64-bits Windows 10 1909 running under KVM on Linux.
GETTING THE PERL SOURCE
I downloaded the latest stable Perl source 5.30.1 from CPAN.
THE COMPILER
The file README.win32 in the root of the distribution contains
compilation instructions and lists various supported MinGW
distributions. I went with the 32-bits compiler from
http://strawberryperl.com/package/kmx/32_gcctoolchain/ version 8.3.0
BUILDING PERL
I went to the win32 subdirectory of the Perl source. In GNUmakefile
I adjusted relevant settings to my build environment. A diff for
this GNUmakefile is included.
I prepended the mingw bin directory to the searchpath and compiled with
gmake
gmake test
There were some test failures:
Test Summary Report
-------------------
../cpan/Win32/t/GetShortPathName.t (Wstat: 0 Tests: 5 Failed: 1)
Failed test: 2
../cpan/Win32/t/Unicode.t (Wstat: 0 Tests: 11 Failed: 8)
Failed tests: 1-3, 5, 8-11
Parse errors: Bad plan. You planned 12 tests but ran 11.
../dist/Net-Ping/t/450_service.t (Wstat: 256 Tests: 26 Failed: 1)
Failed test: 9
Non-zero exit status: 1
../ext/IPC-Open3/t/IPC-Open3.t (Wstat: 0 Tests: 45 Failed: 0)
TODO passed: 25
Files=2661, Tests=1144786, 1844 wallclock secs (79.75 usr + 7.64 sys = 87.39 CPU)
Result: FAIL
gmake: *** [GNUmakefile:1947: test] Error 10
but I hope that these will not impact us.
Installation with:
gmake installbare
`installbare' omits the generation of html.
MAKING PERL PORTABLE
There were hard-coded paths in lib/Config.pm and
lib/Config_heavy.pl, which might 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 in the lib directory under
the names Config.pm.orig and Config_heavy.pl.orig.
INSTALLING MODULES
When adding modules, I prepended the new Perl bin directory to the
searchpath. I downloaded needed modules from CPAN and added them
with
perl Makefile.PL && gmake && gmake test && gmake install
All modules for which tests were defined got a pass. They are, in
order of processing:
Math::Int64 0.54
IO::String 1.08
File::Which 1.23
Digest::SHA1 2.13
Encode::compat 0.07
Encode::Locale 1.05
Windows-specific:
Win32::API 0.84
Win32::WinError 0.04 (just copying WinError.pm to site/lib/Win32)
Win32API::Registry 0.33
Win32::Console 0.10 (no tests)
Win32::TieRegistry 0.30
Win32::Shortcut 0.08 (no tests)
LWP and dependencies, in order of compilation/installation:
Socket 2.029
HTTP::Date 6.05
File::Listing 6.04
IO::HTML 1.001
Try::Tiny 0.30
Test::Fatal 0.014
Test::Needs 0.002006
LWP::MediaTypes 6.04
URI 1.76
HTTP::Message 6.22
HTML::Tagset 3.20
HTML::Parser 3.72
WWW::RobotRules 6.02
HTTP::Negotiate 6.01
Net::HTTP 6.19
Mozilla::CA 20180117
HTTP::Daemon 6.06
HTTP::Cookies 6.08
Test::RequiresInternet 0.05
LWP 6.43 (file libwww-perl-6.43.tar.gz)
JSON support
Cpanel::JSON::XS 4.19
JSON::MaybeXS 1.004000
Compared to the 2019 release, the Date::Parse and Win32::OLE modules
could be dropped.
MODIFICATIONS FOR TEXLIVE
- As explained above: our versions of lib/Config.pm and lib/Config_heavy.pl
compute the location of tlperl dynamically. These files still
contain a hard-coded path for mingw.
- The lib/pods directory has been removed, to save some space.
- The bin subdirectory now only contains exe- and dll files;
batch files and Perl scripts have been removed.
- Copied from mingw32/bin to tlperl/bin:
libgcc_s_dw2-1.dll, libstdc++-6.dll and libwinpthread-1.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 tlshell.exe from the installed TeX
Live, I copied it into the fresh installation.
Both tests were done with 32-bits Windows 7 Home Premium as regular
user and 64-bits Windows 10 Professional as admin user.
tlshell, with its tlmgr Perl backend, appeared to work as intended.
I also successfully ran the uninstaller.
