ruby-sdl-ffi 4.0 `callback': callbacks cannot have variadic parameters (ArgumentError)

[Chris Songer]

I am running OS X 10.8.2

ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin12.2.0]

 

I installed rubygame and all the necessary dependencies. But when I try to write a simple app or run one of the samples it barfs on me with the following error.

/Users/user/.rvm/gems/ruby-1.9.3-p194@global/gems/ffi-1.2.0/lib/ffi/library.rb:365:in `callback': callbacks cannot have variadic parameters (ArgumentError)

Any help in getting passed this issue would be great. I have also tried going back a version of ruby-sdl-ffi and I get the same error.........

I am having the same problem.  I have tried just about everything I can think of even completely removed Homebrew and RVM and reinstalled making sure I did everything correctly and only installing what is necessary.  Have you had any luck fixing this issue?
