People will tell me to ask on matplotlib list but I believe this a more
generic GNU C++ question.
I have been trying to run matplotlib that I built from source on my
linux from scratch like box.
When I try to run an example I get:
bash-4.2$ python2.6 matplotlib-ex1.py
Traceback (most recent call last):
File "matplotlib-ex1.py", line 13, in <module>
import matplotlib.pyplot as plt

undefined symbol:
_ZSt16__ostream_insertIcSt11char_traitsIcEERSt13basic_ostreamIT_T0_ES6_PKS3_i
I see this symbol is in 32 bits libstdc++ library, but does not seem to
appear in 64 bits versions.
bash-4.2$ ldd /usr/lib/python2.6/site-packages/matplotlib/_path.so

libstdc++ is not shown as being linked with _path.so
Any thoughts?
