gdb pretty printing is not working

Question

I am trying to view the contents of C++ STL Containers. I read here that the recent versions of gcc and gdb support pretty printing by default but when I tried to display a map I got the following:

Then, I tried to set up pretty printing according to this answer but still it shows the same output. Can someone please help me out? Thanks.

I am using Ubuntu 16.04, g++ 5.4.1, GDB 7.11.1 and python 2.7.12 (installed from their official sources).

Mark was correct. I built my own version of gdb 8.0 with --with-python option but still I was not able to see container contents. gdb was showing all complex structure. So I followed Mark's suggestion.

You need to create a soft link (auto-load) in your gdb install directory. If your gdb install directory is $HOME/gdb_install then

cd $HOME/gdb_install/share/gdb

ln -s /usr/share/gdb/auto-load auto-load

/usr/share/gdb/auto-load already exists on my Ubuntu installation. It's the gdb version 7.11.1.

After that gdb is showing container contents. Thanks Mark.
