Hi there,

Regarding issues of building Freeglut under Cygwin:

I have always had issues building Freeglut with Cygwin's autotools. So my plan for a
first package of Freeglut for Cygwin is to build it with Visual Studio, as I
currently do for GLUT.
 
This brings some other issue that I mentioned in my last message:
 
----------------------------------------
2- The current version (2.4.0) builds well with my version of Visual Studio (2005), even if it contains only a workspace (.dsw) and projects (.dsp) for Visual Studio 6. VS 2005 can read those and convert them to a solution (.sln) and new projects (.prj) that I can modify. But VS 2005 can not write backward compatible .dsw and .dsp, so I can not prepare patches for these. I could use some tool like prjconvert to perform the conversion, but I have no experience with it and I don't know how well it works. I could test with VS 2005 if it can read back those converted .dsw and .dsp, but that does not necessarily mean that VS 6 could read them properly. Someone else would have to do test that. I could also write to this mailing list what changes I made to the .sln and .prj files, and someone else could then try to apply similar changes in VS 6 to the .dsw and .dsp. 
----------------------------------------
 
Is there any interest in building Freeglut with VS2005 ?

If yes, is there any interest in bringing the changes I made for building with VS2005 to
Freeglut's CVS?
