Hi friends,
I am new to linux.
I am trying to compile a C program (MEEP) using Gcc (ver 4.1.1) under Fedora 6 (IA32). The compile went OK. But when I run ./*.out file, there comes the "Segmentation Fault".
Is that caused by Gcc version? Can it fixed by installing lower version Gcc?
I searched for this error. It sugguests the error might comes from hardware. That the program is trying to access invalid memory address.
Right now I am trying to install lower version Gcc. But I got errors below when I run "make".

"gcc-3.3.6/gcc/f/com.c:11080: error: conflicting types for ‘ffecom_gfrt_basictype’“
"gcc-3.3.6/gcc/f/com.h:236: error: previous declaration of ‘ffecom_gfrt_basictype’ was here"

Thank you.

By far the most common cause of a segmentation fault is a programming error; that is, a bug in the program. The error "comes from" hardware, because it is hardware that detected the error.

Go back to what you were doing before. Don't try to replace the compiler. Compile your program with the -g switch, which tells the compiler and linker that you'll be using a debugger. Then use gdb to find out where in your program the blowup happens.

Get documentation for gdb here:

You have a long road ahead of you, but an interesting one.

Hope this helps.

Hi wjevans,
Thank you!
I just solved this segmentation error by reinstalling MEEP. Because the c++ program is a MEEP tutorial program.
Just don't know why. It just works.
The reinstalling is just like this, instead of the regular install.
make distclean
./configure --enable-debug
make
I got the answer from link

The current GNU GCC compiler is good. The error comes from MEEP installation.
