Bug#730095: ruby2.0: RbConfig::CONFIG['libdir'] does not point to the multiarch dir
Lisandro, Thanks for writing the patch. Cédric, Thanks for trying it and working on it further! Regarding ruby 1.9.1: I think it's safe to ignore 1.9.1; from what I've seen, packages that use cmake to build ruby extensions generally build only for one version, so if 1.9.1 would be broken with a patched cmake, that would only be a temporary situation that can be quickly remedied.

I tested your patch with qtruby and ruby/ruby2.0 from experimental, giving
ruby2.0 as default Ruby interpreter.
It seems that there is a typo in the patch, because I get this error:
CMake Error: Error in cmake code at
/usr/share/cmake-2.8/Modules/FindRuby.cmake:101:
Parse error. Expected "(", got newline with text "
".
CMake Error at CMakeLists.txt:5 (find_package):
find_package Error reading CMake code from
"/usr/share/cmake-2.8/Modules/FindRuby.cmake".
I replaced endif by endif(), and could go a bit further but not far.
I got this error:
CMake Error at
/usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message):
Could NOT find Ruby (missing: RUBY_CONFIG_INCLUDE_DIR) (found version
"2.0.0")

CMakeLists.txt:5 (find_package)
I tried earlier the patch provided in
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=739826#17
(without yours). And it managed to build qtruby against ruby2.0.
It seems that it tries to solve a similar problem to this one.
Could you evaluate it?
About ruby1.9.1 and multiarch, I strongly believe that the plan is to
drop ruby1.9.1 as soon as possible, and that it will not be
multiarchified.
Cheers,
Cédric.

On a second thought, this will not work if ruby1.9 is multiarchified. Is it that the case? I have another ideas to test, but it would be great if you can start testing this or can provide a simple testcase. -- AlfaScorpii: podés converncerla a tu vieja que le esconda el diccionario a el_machi?

Control: reassign -1 cmake Control: retitle -1 cmake: FindRuby cannot handle Ruby 2.0 library in multiarch path Hello Sylvain, thanks for your bug report. Hello cmake maintainer(s).

Before multiarch support, the shared library was also in that directory, but it was mostly a coincidence. DISCLAIMER: I don't know much about CMake. IMO: - CMake's FindRuby macros should not need any help to search for a library in the standard compiler paths, be it the multiarch path (/usr/lib/$triplet) or the legacy path (/usr/lib). - CMake has to be fixed to cope with this, and this is why I am reassigning this bug to cmake. I see 2 ways of doing it: 0) Using archlibdir (new on Ruby 2.0), and falling back to libdir on older Ruby versions: $ ruby1.9.1 -e 'puts RbConfig::CONFIG["archlibdir"] || RbConfig::CONFIG["libdir"]' /usr/lib $ ruby2.0 -e 'puts RbConfig::CONFIG["archlibdir"] || RbConfig::CONFIG["libdir"]' /usr/lib/x86_64-linux-gnu 1) Using pkg-config to detect the presence of Ruby and trusting the compiler to find the shared library in the right path $ pkg-config --libs --cflags ruby-1.9 -I/usr/include/ruby-1.9.1/x86_64-linux -I/usr/include/ruby-1.9.1 -lruby-1.9.1 -lpthread -lrt -ldl -lcrypt -lm $ pkg-config --libs --cflags ruby-2.0 -I/usr/include/x86_64-linux-gnu/ruby-2.0.0 -I/usr/include/ruby-2.0.0 -lruby-2.0 -lpthread -lrt -ldl -lcrypt -lm Please let me know if there is any further information I can provide on the Ruby side. -- Antonio Terceiro signature.asc Description: Digital signature
