[tlbuild] Issues with msys2: failed to link with -lgs, _mkdir not declared, ...

[Mojca Miklavec]

Hi,

This is not really a supported platform, I just wanted to report it
without really expecting a fix.

If I try to build TL on Windows 7 with msys2 --with-system-icu
(because the bundled one doesn't have sufficient patches), the build
fails at dvisvgm because it's unable to find libgs. I would expect it
to either disable dvisvgm or fail earlier than during the linking
phase.

Note this:

checking for gs... no
configure: WARNING: Cannot find GhostScript in your PATH

../../../source/texk/dvisvgm/configure: line 22046: test: : integer
expression expected


After installing ghostscript it fails at

../../../../../source/texk/lcdf-typetools/lcdf-typetools-src/otftotfm/automatic.cc:46:29:
error: '_mkdir' was not declared in this scope
 # define mkdir(dir, access) _mkdir(dir)
                             ^

(Easy to work around, I opened
https://github.com/kohler/lcdf-typetools/issues/17 and would be
grateful for comments from builders running cygwin or the
cross-compiler.)

After that workaround the build succeeds, make check fails at zlib.test:

if ./example; then
  echo '                *** zlib test OK ***'
else
  echo '                *** zlib test FAILED ***'
  exit 1
fi
+ ./example
zlib version 1.2.11 = 0x12b0, compile flags = 0x95
uncompress(): hello, hello!
gzread err:
+ echo '                *** zlib test FAILED ***'
                *** zlib test FAILED ***
+ exit 1
FAIL zlib.test (exit status: 1)


The next one to fail is luaerror.test (in lua52, lua53 and luajit):

FAIL: luaerror
==============

1c1
< ./luatry: (command line):1: test

Then m-tx:

after which I stopped trying.

PS: The patches needed for icu for windows are quite substantial:
    https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-icu
and I don't expect that to be fixed in TL. Libraries need to go to bin
folder and lots of other stuff goes wrong, I didn't try to investigate
too deep. Since we already have W32TeX, cygwin and most likely a
working cross-compiler, this is a much lower priority (= no priority
at all) compared to unix platforms.
