For any of you who have the same problem:

CFX-Pre and CFX-Post didn't work because of a libgcc_s.so.1 version conflict (libstdc++.so.6 of SuSE 10.0 requires version GCC_3.3 - CFX provides libstdc++.so.5)

Solution:

Renamed /usr/local/cfx/CFX-10.0/lib/linux/libgcc_s.so.1 to ..../libgcc_s.so.1.old (delete it if you dare)

and created a symbolic link to the library provided by SuSE:

root@linux:/usr/local/cfx/CFX-10.0/lib/linux# ln -s /lib/libgcc_s.so.1

I'm running on the latest RHEL kernel without any issues but then again RHEL is very consevative and plodding...

Thanks for the solution.

Just to add, I think this only applies when running the 32-bit executables. Another work-around is to set: LD_PRELOAD=/lib/libgcc_s.so.1
