Remote debugging: setting breakpoints in shared libraries

[Klaus Zeitler <Klaus dot Zeitler at alcatel-lucent dot com>]

Hello,
I'm trying to figure out how to debug shared libraries remotely with
gdbserver. My first try was on the same host:

[]$ gdbserver localhost:7777 test
and then in gdb:
(gdb) target remote localhost:7777
(gdb) b function_in_shared_lib
Function "function_in_shared_lib" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
(gdb) c
this works beautifully, i.e. the test program stops at the breakpoint.

Now when I try running the same sequence with gdbserver on a remote host
(and localhost replaced accordingly), gdb doesn't stop at the
breakpoint. My test program doesn't stop.

I found some cumbersome workaround. Put a breakpoint in test program
right after the shared library (dlopen) is loaded, then I manually do:
(gdb) add-symbol-file shared-lib.so <address>


Am I missing something or is this behavior to be expected?

I'm using:
GNU gdb (GDB) Red Hat Enterprise Linux (7.0.1-37.el5_7.1)

Thanks

Klaus
