Get Feel++ Programming Environment

Difficulty: difficulty advanced advanced!

We present here the Feel++ toolchain with both required and suggested tools to either compile Feel++ or use with Feel++.

1. Compilers

Feel++ uses C++14 compilers such as GCC8 and Clang (\(\geq 4\)).

It is mandatory not only to have a C++14 compiler but also C++14 stantard library.

Clang++ is the preferred compiler by far for Feel++, it compiles much faster and use far less memory than G++

A few applications are not built with GCC, GCC ICEs (Internal Compiler Error) on them.

pure traction elasticity applications in feelpp/quickstart

feelpp_toolbox_hdg_*

all toolbox HDG applications are disabled with GCC.

2. Required tools and libraries

Other than C++14 compilers, Feel++ requires only a few tools and libraries, namely CMake, Boost C++ libraries and an MPI implementation such as open-mpi or mpich. The table below provides information regarding the minimum and maximum version supported. A — means it has not necessarily been tested with the latest version but we do not expect any issues. Note that for MPI, an implementation with MPI-IO support would be best.
