[HOpenGL] Re: Fwd: OpenGLRaw

[Andy Gill]

Hi Sven,

After comparing the 'ghc-pkg describe' for GLUT 2.2.0.0 and GLUT  
2.2.1.0,  on my OSX 10.5, this works for me:

   if os(windows) && flag(UseNativeWindowsLibraries)
      cpp-options: "-DCALLCONV=stdcall"
      extra-libraries: glut32
      cc-options: "-DUSE_GETPROCADDRESS"
   else
      cpp-options: "-DCALLCONV=ccall"
      cc-options: "-DUSE_DLSYM"
      if os(darwin)
         frameworks: GLUT
      else
         extra-libraries: glut

So a) + b). Other combinations (i've just tried them) do not work.  
Also, USE_NSADDRESSOFSYMBOL seems deprecated (ld gives link warnings),  
but -USE_DLSYM works, so I've also changed this.

Please let me know how this works out.

Andy
