Dan thanks for the info. I did manage to get a build of gdb (I can live
without floating point). Setting breakpoints does work, however
when I execute the code, it terminates saying that
the application received a SIGILL (Illegal instruction). If I remember
correctly, gdb and other debuggers insert an illegal instruction at
the breakpoint address to cause a trap, or am I totally off?
Does your gdb work with breakpoints correctly?
The sample code was simple:
int main ()
x = 0;
