Hi,

I can't load dynamic libraries with gdb. Below are some commnad lines:

Any hint?

Thanks in advance,

Gdb does not load shared libraries until you actually *run*
the executable. Your output doesn't necessarily indicate anything
is wrong. For example:

$ cat junk.c
int main() { return 0; }
$ cc -g junk.c
$ gdb -q ./a.out
(gdb) inf shared
No shared libraries loaded at this time.
(gdb) b main
Breakpoint 1 at 0x2588: file junk.c, line 1 from /home/paul/a.out.
(gdb) run

Breakpoint 1, main () at junk.c:1
1       int main() { return 0; }
(gdb) inf shared

Why doesn't it load the "/usr/lib/*" libs ?

Wow! You are using an ancient gdb. Please download the latest HP gdb 5.3
from www.hp.com/go/wdb and let us know if you still see the problem.
