How to debug a 64bits application?

How to debug a 64bits application?

[Miroslav Novy]

I used gcc 3.2.1 (downloaded as a package from Sun freeware) with parameter -m64 (generated
code for 64-bit environment) on OS Solaris 2.8 on UltraSPARC-IIe cpu (SunBlade 150) and I can't
debug it.

Example:

#include <stdio.h>

int main (int argc, char *argv[])
{
   printf ("program: %s\n", argv[0]);

   return 1;
}

bash-2.03$ gcc -g -m64 -Wall foo.c -o foo

bash-2.03$ ./foo
program: ./foo

bash-2.03$ gdb foo

Are you using a gdb that was built using the -m64 switch?

Prior to that, you might need for example ncurses built as 64 bit...

BTW, no-one to hint me on the sparc64-linux issue I have with building
gdb? See http://sources.redhat.com/ml/gdb/2003-02/msg00042.html

Your gdb is too old.  Please upgrade.
