Issue
I have compiled a shared library on my Ubuntu 9.10 desktop. I want to send the shared lib to a co-developer who has a Red Hat Enterprise 5 box.
Can he use my shared lib on his machine?
Solution
First point: all of the answers regarding compiler version seem misguided. What's important are the linkages (and the architecture, of course).
If you copy the .so file over to the start system (into its own /usr/local/* or /opt/* directory, for example) then try to run the intended executable using an LD_PRELOAD environment settings. If the linker (ld-linux.so) manages to resolve all the symbols between the two then the program should load and run.
So it should be possible, and reasonably safe (so long as you're not over-writing any of the existing system libraries and just using LD_* /etc/ld.so.preload (in a chroot?) magic to link the target executables to this library.
However, I think it's a bad idea. You have a package management issue. Both Ubuntu and Red Hat have fine package management tools. Use them! (Note the proper place to ask questions about package management would be ServerFault or SuperUser, definitely not SO).
