How to use gdb python debugging extension inside virtualenv

Question

I\'m running ubuntu, and installed the python-dbg package. When trying to use the installed version directly everything works great:

$ gdb python2.7-dbg
GNU          


        

Answer 1

@itai's answer only partially worked for me on Ubuntu Trusty (14.04). I found a couple of other things worked better:

sudo apt-get install python2.7-dbg

then, in the virtualenv:

. bin/activate
mkdir bin/.debug
ln -s /usr/lib/debug/usr/bin/python2.7-gdb.py bin/.debug/python-gdb.py
ln -s /usr/lib/debug/usr/bin/python2.7 bin/.debug/

gdb --args bin/python2.7 ...

This helped gdb find the python debugging symbols as well as the py-bt etc commands.
