xitix5r: You need to follow the compilation instructions properly. If they start with
sudo apt-get install libgtkglext1-dev libfftw3-dev either run the command as written – or at least ensure by other means you have the two packages (and their dependencis) installed. Obviously, you do not because fftw3 is found missing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1882441 Title: Gwyddion Modules not loading: undefined math symbols To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gwyddion/+bug/1882441/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
