I have debugged C++ codes using gdb in Ubuntu 14.04. When I pass a stl container to the print command, it used to print the contents of the container. But then I upgraded to Ubuntu 16.04 LTS a week back. Now those pretty printers are not working. When I print them I get those raw container output you get when you don't have python printers installed.

This guy also has the same problem.

I have libstdcxx/v6/python.pyon my system. I also have libstdc++.so.6.0.21-gdb.py in the auto-load folder. When I print info pretty-printer in gdb, I get a list of stl printers, so I know they are registered. However, my gdb doesn't print stl::list variable. i have enabled pretty-printer, set print pretty on.

My gcc version is 5.4 and gdb version is 7.11.1.Both were installed along with Ubuntu 16.04. I haven't built them manually. So anything obvious I am missing?

In my case, the ~/.gdbinit file had a line:

sys.path.insert(0, '/usr/share/gcc-4.8/python/')

It turned out that changing it into: (4.8->5)

sys.path.insert(0, '/usr/share/gcc-5/python/')

helped.
