How to install this file with Python?

I want to install this file: cvxopt in my Ubuntu 13.04. But I got the following error message:

running install

Any help or suggestions will be appreciated!

    So you don't have lapack and blas libraries. You should be able to install them like

    sudo apt-get install libblas-dev
sudo apt-get install liblapack-dev

    When I tried the compilation it ended the same as for you, after installing the two libraries it finished successfully.

  2. What ended up working for me was installing libncurses-dev

    sudo apt-get -y install libncurses-dev

  3. You need gcc to do that. It resides in a package with the same name.
