How To Install python3-dijitso on Ubuntu 18.04
Introduction
In this tutorial we learn how to install python3-dijitso on Ubuntu 18.04.
What is python3-dijitso
python3-dijitso is:
Dijitso was written to improve a core component of the FEniCS framework, namely the just in time compilation of C++ code that is generated from Python modules, but is only called from within a C++ library, and thus do not need wrapping in a nice Python interface.
The main approach of dijitso is to use ctypes to import the dynamic shared library directly with no attempt at wrapping it in a Python interface.
As long as the compiled code can provide a simple factory function to a class implementing a predefined C++ interface, there is no limit to the complexity of that interface as long as it is only called from C++ code, If you want a Python interface to your generated code, dijitso is probably not the answer.
Although dijitso serves a very specific role within the FEniCS project, it does not depend on other FEniCS components.
The parallel support depends on the mpi4py interface, although mpi4py is not actually imported within the dijitso module so it would be possible to mock the communicator object with a similar interface.
This package installs the library for Python 3.
