Hi J-S, The only that comes to my mind is change all RPATHS on dependent libraries. This is a little bit complicated, and maybe a "I need to reinstall OS" :S.
Using "otool -L" you can see all the rpaths associated to a library or executable in mac. Using "install_name_tool" you can change a concrete rpath for a library or executable. Some preinstalled frameworks and libraries on macosx have their rpaths prefixed, so doing this you can point all these libraries to your mesa libraries. To avoid a complete mess in your system, maybe you can copy all frameworks and libraries to a dir, and change all rpaths of all these libraries and your applications. But this is really tricky. There are also the env var DYLD_FRAMEWORK_PATH, that could help. Good luck! Rafa. 2010/9/20 Jean-Sébastien Guay <[email protected]>: > Hi Jordi, > >> Did you try LD_PRELOAD?
