Hi folks, I downloaded, compiled and installed GiNaC using the following version of gcc: gcc -v Using built-in specs. Target: i686-pc-linux-gnu Configured with: ../configure Thread model: posix gcc version 4.0.2 I now appear to have a working setup. E.g. I can run "ginsh": ginsh - GiNaC Interactive Shell (ginac V1.3.5) __, _______ Copyright (C) 1999-2006 Johannes Gutenberg University Mainz, (__) * | Germany.

When I compile and run my test program, however, I get the following error message: /usr/lib/libstdc++.so.6: version `CXXABI_1.3.1' not found \ (required by /usr/local/lib/libginac-1.3.so.2) Am I perhaps missing some environment variables or compiler switches here? I have the following files: /usr/include/c++/3.3/cxxabi.h /usr/local/include/c++/4.0.2/i686-pc-linux-gnu/bits/cxxabi_tweaks.h /usr/local/include/c++/4.0.2/cxxabi.h I compiled my program with the following command: c++ -g complete41.cpp -o complete41 -I/usr/local/include -lcln -lginac Any help would be appreciated.
