pNbody is fully based on standards tools. Most of them are installed by default on a linux system.

The basic module of pNbody needs :

3. a C compiler like gcc:

   http://gcc.gnu.org/

4. the Gnu Scientific Library (GSL):

pNbody uses the following python modules (if missing, those modules will be automatically installed). It is however recommended to have at least numpy installed first (pip install 'numpy<2.0').

5. numpy-1.0.4 or higher, but smaller than 2.0.0:

6. Pillow 8.4.0 or higher:
