Hi,
I want to set breakpoints in shared lib sources while executing another
program.But the symbol is being overridden whenever I use
file test.so
Please let me know if there is a way to set breakpoints in shared library
sources while debugging an application which uses this.
--------------------------------------------------------------------
warning: shared library handler failed to enable breakpoint
is the warning I got!

Don't use file. It needs to be automatic or it won't work at all.

This is the problem. You didn't say what platform you're debugging,
how you're running GDB, or anything else - one of those is to blame.

Sorry!
gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-20)
This GDB was configured as "i386-redhat-linux-gnu".

What system are you running GDB on?
How are you running GDB?
Please send a transcript of a session which demonstrates the warning.

Here is the sequence :
------------------------------------------------------------
(gdb) b child.cc:4
No symbol table is loaded. Use the "file" command.
(gdb) file libmem.so
Reading symbols from libmem.so...done.
Using host libthread_db library "/lib/tls/libthread_db.so.1".
(gdb) b child.cc:4
Breakpoint 1 at 0xdf8: file child.cc, line 4.
(gdb) run
Starting program:
/root/libmem.so
Breakpoint 1 at 0x80000df8: file child.cc, line 4.
warning: shared library handler failed to enable breakpoint
-----------------------------------------------------------------
Actually my requirement is to make breakpoints work in a shared library
while debugging another application which uses the above shared library.
The child.cc is the source file for libmem.so
(g++ -g -shared -o libmem.so child.cc)
Please let me know how can i do this.

You should not have to do anything. Don't mention the shared library
explicitly to GDB - it doesn't need that. Just load the real
application that you want to debug and run it. You should be able to
set a breakpoint in the shared library.
If you are using an old version of GDB, upgrade to the latest release.
