The next thing to examine is to see if your program needs to be ported to 64-bits. Another user gave a good explaination of some of the things you’ll need to do when porting from 32 to 64-bits. See:
Try running your P4 executable on the SGI. (If you haven’t already, I believe Gentoo requires you to install a 32-bit emualtion package before you can run 32-bit executables.) You can also try compiling with “-tp k8-32” to create a 32-bit executable, however this might not work since I’m not sure if Gentoo has 32-bit library support.
If the 32-bit executable runs correctly, then there is a good chance that your errors are due to a porting problem.
