Unhappy gdb won't recognize 64 bit executable on my RedHat 64 bits box


Hi, I am fiddling around with a new Dell Precision 670 which came with a preinstalled RedHat on it. I'm not very happy with this installation, but for lack of time, I am stuck with it for the moment.

The installation is quite confusing as everything with lib in it comes in pairs: lib and lib64. It seems also that a lot of the code is 32 bits (for example the X system seems to be running the old 32 bit libraries).

On the other hand I compiled code with the lib64 and it seems to be running smoothly, albeit I can't debug it.

This is what gdb replies to me:

This GDB was configured as "i386-redhat-linux-gnu"..."/home/omar/FEMA/1d/heat_semilin": not in executable format: File format not recognized

So most likely, I need to reconfigure gdb for it recognize the 64 bit executables. I would need something like "x86-64" instead of "i386" in the above line...

Any idea? (Please email me, I'm not very often here.)

Regards, OL
