Failed to read a valid object file image from memory (PLEASE HELP)

Failed to read a valid object file image from memory (PLEASE HELP)

[Lenny K]

Hi all,

I've cross-compiled gdb version 6.8 to powerpc-linux-gnu.
After installing it on my ppc embedded based machine - I ran it on
this simple C program:

#include <stdio.h>

int main()
{
      printf("Hello World\n");
      return 0;
}

And I got the following error:
gdb hello

Please help...

Thanks!

When you say "cross-compiled" -- what exactly do you mean?
You used some other machine architecture to build a *native*
ppc-linux-gnu gdb?  And then you're running the gdb on the
ppc-linux-gnu machine?
