ruby: ruby gem installation causes segfaults

[dj_mook@…]

If you install the ruby macport on lion and then install rubygems from source, any attempt to install a gem results in a segfault.

sudo gem install sinatra
ruby-1.8.7-p352/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault
ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin11.0.0]

According to ​http://www.frymanet.com/2011/07/rvm-ruby-1-8-7-and-osx-lion/ ruby does not work well with the default llvm compiler in lion.

Using the solution from the article I patched the Portfile to set CC=/usr/bin/gcc-4.2 as a configure argument.

After rebuilding ruby with the new portfile and then installing rubygems from source, I can now install gems without problem.

Macports version 2.0 rc1.

Does it work with clang? It's probably better to use it if it does.

[snc@…]

I'm seeing this problem in snow leopard with llvm-gcc as well.

[snc@…]

Using the configure.compiler clang macro suffices: ./configure correctly switches to clang.

[snc@…]

Clang continues to result in segfaults.

This port builds successfully with configure.compilter gcc-4.2.

Should we test for the OS version to decide between gcc-4.2 and gcc-4.0? or just detect llvm/clang and switch it back if set?

[snc@…]

Behold the hierarchy for picking default compilers.

[snc@…]

change configure.compiler to gcc-4.2 when defaulted to llvm-gcc-4.2 or clang

[snc@…]

I've attached a patch to detect default compilers of llvm-gcc-4.2 or clang, and change it to gcc-4.2.
