I was trying to install ruby-llvm.
I could install llvm with brew install llvm -shared, and I also could install ruby-llvm with sudo gem install ruby-llvm command.
However, when I tried to run the examples, I got these error messages.
/Users/smcho/.rvm/gems/ruby-1.9.3-p194/gems/ffi-1.1.5/lib/ffi/library.rb:121:in `block in ffi_lib':
Could not open library '/DIR/.rvm/gems/ruby-1.9.3-p194/gems/ruby-llvm-3.0.0/lib/libRubyLLVMSupport-3.0.0.dylib':
dlopen(/DIR/.rvm/gems/ruby-1.9.3-p194/gems/ruby-llvm-3.0.0/lib/libRubyLLVMSupport-3.0.0.dylib, 5): no suitable image found. Did find: (LoadError)
/DIR/.rvm/gems/ruby-1.9.3-p194/gems/ruby-llvm-3.0.0/lib/libRubyLLVMSupport-3.0.0.dylib: mach-o, but wrong architecture
I checked that the dynamic library is 64bit.
file /DIR/.rvm/gems/ruby-1.9.3-p194/gems/ruby-llvm-3.0.0/lib/libRubyLLVMSupport-3.0.0.dylib
libRubyLLVMSupport-3.0.0.dylib: Mach-O 64-bit dynamically linked shared library x86_64
And it seems that ruby is running in 32bit mode. ruby 1.9.3p194 (2012-04-20 revision 35410) [i386-darwin11.4.0].
How can I resolve this issue? Is there a way to download 32bit version of ruby-llvm or 64bit version of ruby?
It seems like you've installed ruby in 32 bit mode. Would installing ruby in 64 bit mode solve the problem?
To force 64 bit you could try the following with a recent version of RVM:
$ rvm install 1.9.3 --64
or $ rvm install 1.9.3 --with-arch=x86_64
(from: http://www.engineyard.com/blog/2012/rvm-stable-and-more/)
For compiling 32 bit mode ruby on OS X we have --32, --64 and --universal flags:
$ rvm install 1.9.3 --universal # to build fat binary including both 32 and 64 bit binaries
$ rvm install 1.8.7 --32 # to build only 32 bit ruby
$ rvm install 1.8.7 --with-arch=i386 # is equivalent to the 32 bit one, but is available only via RVM, ruby 1.8.7 sources do not support it.
