My first try would be to compile the code on a desktop machine and then ship
the executable to the cluster (provided it's an x86 cluster, of course). That
way, you could simply link everything statically, and you're independent of the
actual cluster environment.
I haven't tried compiling Gecode with gcc < 4.2 for a long time, but I'm pretty
sure it wasn't just some components that wouldn't compile, but data structures
in the very core of Gecode. Some things (mostly in the set constraints module,
I think) were even miscompiled, so the code would simply crash although it was
actually correct. That's why we decided not to support old versions of gcc any
longer.
Cheers,
Guido
