Help with GDB debugging shared libs from an attached process

[steveo622]

Hello,

I am trying to debug one of my shared libraries that gets called from a java application through JNI to C++.

I enter the gdb environment and attach to the running java process. I set my dir to where the necessary source code is and then set my breakpoint. Here is a listing of the output from gdb...

(gdb) b /home2/scolbert/MMAXWeb5.2/PlanningServer/PlanningEngine/SubcubeDataMgr.cpp:228
Breakpoint 2 at 0xc20c2a0c: file SubcubeDataMgr.cpp, line 228.
(gdb) cont
Continuing.
warning: reading `flags' register: Protocol error
warning: reading `r31' register: Protocol error
warning: Cannot insert breakpoint 2:
warning: Temporarily disabling shared library breakpoints:
warning: breakpoint #2
warning: reading `flags' register: Protocol error
warning: reading `r31' register: Protocol error


Notice that my breakpoint gets disabled. WHy is that happening? How can I get past this issue?

Thanks,


Steve Colbert
