Actually, segmentation errors are generally software bugs, but there are some programs (e.g. gcc) that are so well-tested and widely used that receiving a segmentation error in one of them is likely a hardware bug. It could easily be that that the program in question is either not 64-bit clean or is otherwise /slightly/ not portable between the two different environments. (For example, it expects structure packing to act like gcc 3.3 instead of gcc 3.4.) Finally, it could be a transient error that isn't strictly due to any incompatibility, but does show up more often (or at all) in a different environment (prelink vs. non-prelink; swaping vs. not; memory empty/zero'd vs. not, etc.) > This is the first time I face this problem.

AMD processors and the 64-bit linux kernel are quite happy running 32-bit applications (although, that may require a particular kernel option). However, 32-bit applications are not so happy loading 64-bit libraries or (IIRC) vice-versa, so you may not have the libraries you need. A dlopen() call that program assumes works (doesn't check for an error) might cause your segmentation fault, BTW. "multilib", in gentoo-amd64-speak, should cause 32-bit versions of some (many? most? all?) libraries to be built, but requires a profile change and may force a emerge -e (guessing here, I'm not sure what, if any special migration is needed when going to multilib from no-multilib or vice-versa) even without multilib, a number of 32-bit libraries are available through the emul-* packages in gentoo. > Well, thanks all the people helping me with this hard > work of building my linux system! While I don't think I've helped with your issue, I'd be more quick to blame it on the software you are trying to install, possibly in combination with a/some missing libraries. You might be able to see what is wrong with an ldd/strace against the application. -- Boyd Stephen Smith Jr. [EMAIL PROTECTED] ICQ: 514984 YM/AIM: DaTwinkDaddy -- gentoo-user@gentoo.org mailing list
