> Warmly > Akshay Pande Did you download a binary for Sage, or did you download the source code and build Sage from source? I suspect you downloaded the binary, but I may be wrong. Your system either lacks libstdc++.so.6, or its in a place which can't be found. This is the C++ library that is used as part of gcc. I've proposed before that this be included in the Sage distribution, though whether it actually is done so I don't know. What is the output of $ g++ -v $ which g++ If g++ is not installed on your system (unlikely but possible), then you will need to install that. I'd have a hunt around your system, and see if you can find a file which at least starts with libstdc++. If you can find libstdc++.so, then copy it to $SAGE_ROOT/local/lib. I would not advise putting it in /usr/lib, despite the error message.
