ffi-inliner's Issues

Migrate to Jeweler or similar

It should be nice to migrate from MrBones to a more modern solution like Jeweler or similar.

a failure is cached

Currently with this code:

module MyCLib
  extend Inliner
  inline do |builder|
    builder.library 'Winmm2'
    builder.c 'int func_1() { return 0; }'
  end
end

If you run it the first time it fails (there is no Winmm2 library).
Removing the offending line and running it again and it still fails, though in reality it should recompile and succeed.

no rake spec task in 1.8 windows

It doesn't appear as an option for some reason...I'd be happy to refactor the rakefile to use jeweler if that would help the situation.

TCC generated shared libraries do not work in Windows

When using TCC as compiler for TCC, I found that symbols do not get exported automatically.

Symbols needs to be exported so FFI can find them:

ruby 1.8.6 (2009-08-04 patchlevel 383) [i386-mingw32]
C:/Users/Luis/.gem/ruby/1.8/gems/ffi-inliner-0.2.2/lib/ffi-inliner/inliner.rb:141:in `build': C:/Users/Luis/.gem/ruby/1.8/gems/ffi-0.5.1-x86-mingw32/lib/ffi/library.rb:77:in `attach_function': Function 'say_hello' not found in [C:/Users/Luis/.ffi-inliner/MyLib_92ce.dll] (FFI::NotFoundError)

        from inliner-test.rb:7

Since TCC do not offer a two step compiler linker process, the option is use -rdynamic parameter which is going to export all the symbols defined as inlined functions.

Thank you

requires fileutils?

Hmm.

Implement FFI::Struct marshalling

needs to specify appropriate bones version

perhaps I'm just clueless here, but installing the bones gem seems to need a specific version, perhaps?

map C line numbers to their ruby equivalent

Currently when a C file fails, the log file generated shows error line numbers based on the C file, which don't map easily to the ruby file they came with.
This is a feature request to map them a bit closer.

I believe the pre processor macro desired is something like

#2 "C:/Users/packrd/.ffi-inliner/MyCLib_f925.rb" 2

Though I've never used it before...

parse failure

module MyCLib
  extend Inliner
  inline do |builder|
    builder.c <<-CODE
    int func_1() { return 0; }
    CODE
  end
end

fails to parse for some reason.

module MyCLib
  extend Inliner
  inline do |builder|
    builder.c <<-CODE
    int func_1() { 
       return 0; }
    CODE
  end
end

works though.

dependencies.rb:239:in `require': no such file to load -- ffi/inliner (LoadError)

I tried install gem 'tesseract-ocr', I added 'tesseract-ocr' to Gemfile and ran 'bundle update' with succesful.

What is wrong? I tried run on Windows 7 and Centos 6 - error is the same.

Seems this does nothing with regard to Winmm?
