<HTML>I am searching for open source multimedia and 3-graphic tools and software development tools that will run with Fedora 4 linux. I have been seeing some apparent problems with applications that ran with older versions of Fedora that will no longer run with Fedora 4. The problem may be associated with using GCC 4.0 , although I am not sure. In any case here is a list of free applications that I have tried to install so far. Successes - Borland Java Builder - free version Audacity - sound editor Argo UML - universal model language tool Flight Gear - airplane simulator OpenScenegraph - 3-D graphics tool set SGI Performer - 3-D graphics - limited free demo version MainActor - video editor - limited free demo version xine - DVD player Failures - Blender 3-D editor - compiles but does not seem to work properly. Open Scene graph Editor - will not compile under GCC 4.0 Virtual Terrain Builder - will not compile under GCC 4.0 Timidity - Midi player - compiles but will not play midi files , does not create timidity.cfg file. It appears that "sound fonts" are missing. Also the built in kmidi player does not generate any sound output. I have upgraded the Fedora kernel and installed the latest version of alsa, but it does not seem to fix the midi problem. Borland kylix - I have not had any success with this C++ development tool since I upgraded from Fedora1. There are rumors that Borland may release an upgrade to kylix , but the rumors may have no substance. Has any one had success with any of the applications listed above?? So far the audacity sound editor is the only one that I have actually used for anything. It seems to work well and I would recommend it. I have had extensive difficulties with missing dependency libraries , and incompatible versions that generate undefined linker and run time symbols. Overall there seems to be a lot of incompatibilities with source packages that were built for versions of linux other than Fedora 4. </HTML>
