I have updated freeglut to version 2.2.0 in fedora-devel. The new version should be API and ABI compatible with glut 3.7 to the best of my knowledge, as that is one of the main goals of the freeglut project. When upgrading to these new freeglut packages, they will automatically obsolete and uninstall any "glut" and "glut-devel" package present on the system. The new packages have a virtual provides set for "glut = 3.7" and "glut-devel = 3.7" for rpm dependancy compatibility with rpms which may be installed already which require either of the two. I have done some preliminary testing already, however there are 3 levels of testing that need to be done. Please test as many of the following scenarios as you can: - Install binary software that is already linked dynamically to Mark Kilgard's GLUT (or install GLUT and build some GLUT applications). Then upgrade to freeglut, and run the existing GLUT applications. This tests ABI compatibility from glut->freeglut. - With freeglut and freeglut installed (which will remove glut and glut-devel automatically), rebuild some applications that use GLUT, so that they've linked against freeglut instead. Test them, and note any problems or incompatibilities. This tests API compatibility. Note that no modification to the application's source is necessary. - With applications linked to freeglut as per above, now remove freeglut with "rpm -e freeglut freeglut-devel --nodeps" and reinstall the original glut from RHL 9. Now run-test the GLUT apps. This tests freeglut->glut ABI compatibility. Some software which you may find useful for testing include Mesa-demos, and Really Slick Screensavers (rss). There are many other GLUT using apps out there as well, however Fedora Core itself has no dependancies on GLUT currently, so 3rd party software is required to do this testing. If possible, please perform the above testing if possible by using the Red Hat supplied Mesa OpenGL implementation which is included with XFree86, so that we can get adequate test coverage with Mesa libGL, and DRI drivers. If you are using proprietary drivers from Nvidia, ATI or another 3rd party, you would have to uninstall these drivers temporarily and reinstall the Fedora provided libGL, etc. so that we know what is being tested is what comes with the OS. It is also important however for people to test with proprietary libGL from Nvidia, ATI, etc. as well however, as that will give additional compatibility test coverage with alternative libGL implementations. Interestingly enough, one of the problems with Mark Kilgard's original GLUT, is that it has a bug in it which causes it to not work properly with Nvidia and other libGL implementations if it has been compiled with Mesa, because mesa implements some extensions which are not widely used, and are not present in all vendor's libGLs out there. Freeglut should not suffer from this limitation, and so it should work equally well with both Mesa libGL and with Nvidia/ATI/etc. libGL - at least in theory. If you encounter any API or ABI incompatibilities in the above testing, or any bugs/problems with the library itself, please report them to the upstream freeglut bug tracker on sourceforge, which is located at: http://sourceforge.net/tracker/?atid=101032&group_id=1032&func=browse If you report a bug there, feel free to also file a tracker bug in Red Hat bugzilla as well, with a URL pointing to the upstream bug report for me to track. I'll monitor the upstream report also. If you discover any problems with the RPM packaging of freeglut itself, please report the bug in Red Hat bugzilla instead of upstream. Thanks in advance for any testing. -- Mike A.
