I have a coredump generated on other device for my C code. I am trying to debug that core on my system, considering memory corruption as probable cause.
Please provide steps to install & use 'gdb-heap' on my system. Please help me.

/home/user1$ cat gdb-heap-commands
python
import sys
sys.path.insert(0, "/usr/share/glib-2.0/gdb")
sys.path.append("/usr/share/glib-2.0/gdb")
sys.path.append("/home/user1/gdb-heap")
import gdbheap
end

/home/user1$ gdb -x gdb-heap-commands

You may need to revise /home/user1/gdb-heap to be /home/user1/gdb-heap/heap

rogerhu commented

Scratch that...confirm that you have gdbheap in /home/user1/gdb-heap.

aniket1729 commented

No I don't have 'gdbheap' within '/home/user1/gdb-heap'

~$ ls gdb-heap
gdbheap.py LICENSE-lgpl-2.1.txt LICENSE.txt object-sizes.py run-gdb-heap
heap LICENSE-python.txt make-release.sh resultparser.py selftest.py

I verified with both https://github.com/rogerhu/gdb-heap & https://fedorahosted.org/gdb-heap/

rogerhu commented

Yeah gdbheap.py I mean.

Please help me to proceed further and resolve error.

rogerhu commented

My guess is that init.py needs to be added. Please create a blank file and see if it works.

aniket1729 commented

Still getting same error.

rogerhu commented

Works fine for me:

cd /tmp
sudo apt-get install libc6-dev libc6-dbg python-gi libglib2.0-dev python-ply
git clone git@github.com:rogerhu/gdb-heap.git
cd /tmp/gdb-heap
(gdb) python
import sys
sys.path.insert(0, "/usr/share/glib-2.0/gdb")
sys.path.append("/usr/share/glib-2.0/gdb")
sys.path.append("/tmp/gdb-heap")
import gdbheap
end

I think this is a non-issue. Feel free to comment but I think your dir structure is probably at issue.
