  • A recent version of Python (2.7) with the numpy module
  • A Fortran compiler
  • A C/C++ compiler

Please read the README file before the installation, then

python setup.py install --prefix=/opt/aster.

We advise you to use Intel compilers if they are available for Code_Aster, and Mumps and use GNU compilers for the other embedded software.
