Public bug reported:
libstdc++6-4.8-dbg on installs /usr/lib/debug/usr/lib/x86_64-linux-
gnu/libstdc++.so.6.0.18-gdb.py. This is supposed to autoload the pretty-
printers for libstdc++ into gdb when a program is started. However, its
logic for determining the path to set seems to be broken, because it
leads to this error in gdb:
Traceback (most recent call last):
File "/usr/lib/debug/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.18-gdb.py",
line 60, in <module>
from libstdcxx.v6.printers import register_libstdcxx_printers
ImportError: No module named 'libstdcxx'
DIR = /usr/lib/x86_64-linux-gnu/../share/gcc-4.8/python
Traceback (most recent call last):
File "/usr/lib/debug/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.18-gdb.py",
line 60, in <module>
from libstdcxx.v6.printers import register_libstdcxx_printers
ImportError: No module named 'libstdcxx'
And STL containers are not pretty-printed. Manually adding
/usr/share/gcc-4.8/python to the PYTHONPATH (e.g. by writing Python code
in .gdbinit) fixes the problem.
I am running Ubuntu 13.10 on x86_64. I've also noticed the problem on
13.04 with libstdc++6-4.7-dbg.
