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.
