Greetings;
In my quest for optimizing my network usage (very slow connection), I've been migrating my
archlinux installation to a sort of gentoo setup, building my own packages from source repos.
In the process of that, I've written a PKGBUILD file to compile ruby, lib32-libruby, and
mingw-w64-ruby.

While the recipe works fine against ruby 2.1.5's source code, I'm running into issues with
ruby-trunk, either from the svn repo or the git mirror. ruby and lib32-libruby both compile
fine, but the mingw-w64 build fails at attempting to link ruby.exe and rubyw.exe, citing a
number of undefined references to Init_ in extinit.c, while the dll, dll.a, and static.a
files compile just fine. While I am solely building for the sake of using it as a linked in
library for embedding this is hopefully of little concern to me, however I feel it
is my duty to report the issue here.

Could you show your exts.mk file?

And...

• --enable-static is not a valid option
• --disable-install-doc implies --disable-install-rdoc and --disable-install-capi
• --with-tcl-dir and --with-tk-dir don't make sense as they are equal to --prefix
• -O2 -g -pipe -Wall and _FORTIFY_SOURCE are redundant

extmk.rb: no EXTOBJS to main if enable-shared

• ext/extmk.rb: as all extension objects including initializations
  of ext and enc shouild be linked to libruby if enable-shared,
  EXTOBJS should not be linked to main programs.

Ah, one second. Some of the redundancy is due to archlinux shipping a pair of configure wrapper scripts to make looping the build for i686 and x86_64 w64-mingw32 simpler; I was not aware that --disable-install-doc implies the others, I adopted a PKGBUILD that last worked on some 2.0.0 ruby version, and I figured if it wasn't broke, don't fix it.

Give me a bit, I'm doing real physical work at home, and I'm running the build again against the latest svn to get the exts.mk file untainted by my experimentation.

Ah, many thanks! I just reran makepkg, which updates source of repo-based builds, and it worked. Was scratching my head for a second there, then I noticed your post with the fix. Huge thanks, quick resolution :)
