rpav / c2ffi-ruby Goto Github PK

Hello @rpav

c2ffi is amazing.

I am surprised that c2ffi is not well known in the Ruby community.
I want to improve c2ffi-ruby and upload it as a package on the RubyGem server.

But I'm not sure about the license. May I freely improve it and redistribute it?
If not, I will make a Ruby tool to output FFI bindings from json files generated by c2ffi from scratch without referring to c2ffi-ruby.

Keep up your great work!
Thank you.

I'm trying to run this using MRI 2.4.1 (and 2.5.0). Given the example dir, I tried running it. Here's my output:

OSX-Guest:simple cremes$ ../../../c2ffi/build/bin/c2ffi -M macros.h -o example.spec example.h
c2ffi warning: Unhandled environment: '' for triple ''
OSX-Guest:simple cremes$ ../../../c2ffi/build/bin/c2ffi -o macros.spec macros.h

This is on OSX 10.12.6 with LLVM 5.0.0 installed (via brew) using both MRI 2.4.1 and 2.5.0.

What's the last version you tested with? Project is about 5 years old so I'm thinking it was probably MRI 1.9.3. Any chance for an update to a modern ruby release?
