Do you have received any answer? Thanks Domenico 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.

[Matplotlib-users] Installation problem
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.

That means, if an underlying dependency changes, it often doesn't rebuild enough to keep things in sync. You may want to try rebuilding everything after first completely removing the build directory to force a complete rebuild. Do numpy first then matplotlib. ...but maybe you've tried that already, in which case, I don't know off hand...

Yes, I learned the hard way a long time ago about having to rm -rf build/ when rebuilding python packages. I have tried this here, but I still have an issue. I am currently trying to rebuild with a different compiler and playing with environment variables. I would love any other suggestions.

Hi Darren, Yes, unfrotunately I tried this as well to no avail.
