it seems like we can run gcc-4.2 binaries on a redhat-ws4 system (main compiler gcc 3.6.4) . I was a bit surprised . Forward comparability , or gcc-4.2 libraries installed ? Anybody care to comment on this or the reliability of same ?
The GCC version generally has nothing to do with this. I have GCCs up to gcc-4.5 for Red Hat Linux 7.3 which originally had gcc-2.96. Apps compiled with the newer GCCs and linked against the RHL 7.3 glibc-2.2.5 surely will run on RHL 7.3. But if I would compile and link an app on or for some uptodate distro using just the same GCC version for that as for RHL 7.3, then that of course wouldn't run because being linked against some much newer glibc like 'glibc-2.11.x' or something... So the issue is related to the C library version, not the GCC version!
