Pre-built binaries are supported on Linux and Windows (x64) platforms from https://rubygems.org/gems/iup-ffi:

$ gem install iup-ffi

Other Platforms

To make this work on other platforms:

  • download the source code

  • download the CD, IM and IUP shared libraries from https://www.tecgraf.puc-rio.br/iup/en/download_tips.html into the appropriate "lib/library" folder: Linux68_64 and Win64_dllw6 are used in the pre-built binaries.

  • add a new category to lib/iup-ffi-plain.rb
