Re: [ruby-ffi] Cross-platform C code packaged in a gem

Hi Hugo,

Ruby-LLVM does exactly this for the support library. We let rubygems build the extension by invoking rake. Here are the relevant bits.

declare the extension: https://github.com/ruby-llvm/ruby-llvm/blob/master/ruby-llvm.gemspec#L22
define Rakefile for build process: https://github.com/ruby-llvm/ruby-llvm/blob/master/ext/ruby-llvm-support/Rakefile
loading the library by its relative path: https://github.com/ruby-llvm/ruby-llvm/blob/master/lib/llvm/support.rb#L15-L17

HTH,

Was anyone able to package cross-platform C code in a gem and loading
it with FFI?

I'm having a hard time compiling and linking the code (especially on
Windows) using extconf.rb. I looked at all the github FFI projects
(the one listed on the Wiki) and none of them seems to be doing
something similar.

Thanks
