Hi Domenico,
Yes, the problem was resolved and it all works great now. I can't
tell you exactly what fixed it because I am no an expert on library
files, compiling stuff, etc. However, here is what I thought: I
thought that the libstdc++.so was not finding the correct library
files for the compiler or that there was a difference between the
version of gcc compiler used to make the libstdc++.so file and the gcc
compiler that I used to build other python related dependencies like
numpy. So here is what I did: (I'm sorry but I do not know how to do
this in wondows. I only know what I did linux)
1) Installed a brand new version on the gcc suite of compilers on my
computer. (I took a long time to do this, but I wanted to make sure
that all the library files and the compilers that I used matched up
and worked well.) I seem to recall that there was one flag which was
important: I think it was --with-gnu-ld, which tells gcc to use the
gnu ld program for linking library files. Please also be sure to set
the LD_LIBRARY_PATH variable to find all the appropriate library
files.
2) I rebuilt LAPACK and ATLAS (because I was having trouble with them
too and I knew that numpy depended on the lapack routines.
3) I rebuilt numpy.
4) I installed matplotlib.
I know this probably seems like overkill, but it is what I had to do
to get my machine working.
Sorry I can't be of more help, these issues are pretty specific to the
individual computer.
Best of luck,
Frank

Hi,
I am sorry to bug you all with an installation problem, but I need
some additional help to get this figured out.I previously had a matplotlib installed and working fine, but it was
necessary for me to redo some other installations like numpy when I
needed a complete lapack library. This also led to me installing
another version of g77, because numpy needed a specific library that
was only provide by the g77 version of fortran for some reason.
Anyways, numpy works great but I went back to install matplotlib and I
ran into trouble. After the installation process, if I try to import
matplotlib.pylab I get the following errors:from matplotlib._path import affine_transform
ImportError: /ronaldo/pkg/dfranci/gcc-g77-3.4.6/lib64/libgcc_s.so.1:
version `GCC_4.2.0' not found (required by /usr/lib64/libstdc++.so.6)Is this a problem that I can fix in the matplotlib installation or do
I need to go back up to the numpy installation?I should note that I do not have gcc-4.2.0 on my system.
Thanks in advance,
