gdb problem

Hello everyone,

I have QNX 6.2.0 installed. I’m trying to use gdb, but It doesn’t work at all. Example:

$ gcc -g xmpl.c -o xmpl
$ gdb xmpl
GNU gdb 5.0 (UI_OUT)

This GDB was configured as “–host=x86-pc-nto-qnx --target=ntox86”…
(gdb) l
1 #include <stdio.h>
2 #include <stdlib.h>
4 int main (int argc, char **argv)
5 {
6 int j;
7 j=argc+1;
8 printf("%d, %d\n",argc,j);
9 puts(argv[0]);
10 }(gdb) b 8
Breakpoint 1 at 0x8048421: file xmpl.c, line 8.
(gdb) run hello
Starting program: /home/grillo/varias/xmpl hello
(gdb) print argc
No symbol “argc” in current context.

Why doen’t it stop at the breakpoint? What can I do? Is there any other gbd version for QNX? (I tried to install gbd 6.3, but i couldn’t).

Thank you.

The QNX version of gdb doesn’t actually continue the program - use the ‘continue’ command

I’ve used it. And it does work. Thank you! :- >>
