You can't do this as the libraries, glibc, and gcc versions are all different between centos4 and centos5. > Has anyone here seen similar behaviour and what would be a possible > solution? (to compile under 5 in such a way that it runs on 4) You can only do this if you're building in a chrooted environment with the c4 libs. You'd have to use a tool like mock to do this. > Any hints (how trivial they may appear to you) are most welcome. Doing things like this are getting easier, but I wouldn't call them 'trivial' just yet. -- During times of universal deceit, telling the truth becomes a revolutionary act. George Orwell
