I know this is quite a handwaving, stupid question, but I don't know where else to ask it and maybe somebody here can at least point me into the right direction, because I'm stuck.
I have a program package that were using here (OpenFOAM for those who know it). My problem is that when I compile and link this package on CentOS 5, it won't run on CentOS 4.x-machines but stops with a floating-point-exception. The funny thing is that my experiments with strace and gdb indicate that the problems occur during the loading of an .so (that does not belong to the package). I was able to remove that so from the build, the program then failed with similar symptoms at another library.
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)
My problem is, that moving all machines to CentOS 5 is not possible, because our cluster-solution (Rocks) is based on 4.
Any hints (how trivial they may appear to you) are most welcome.

Compile on 4?

You can't do this as the libraries, glibc, and gcc versions are all different between centos4 and centos5.

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.

Doing things like this are getting easier, but I wouldn't call them 'trivial' just yet.
