This variable could be set in your shell configuration (e.g. in .bashrc) or by using a separate OpenIFS platform configuration script which could be loaded prior to using OpenIFS. We describe the set up of the platform configuration script in a later section on this page. 

 Build OpenIFS

In the next step the model binary executable (and other helper programs) will be built.

Requirements

The following software is required to build OpenIFS:

• Either Intel or GNU compilers are supported
• MPI, either MPICH or openmpi
• netCDF
• any others?

In contrast to earlier model versions, the building of OpenIFS 48r1 is no longer based on the FCM configuration manager, but uses from now on the ecbuild ECMWF build system that is also used for the ECMWF IFS model, and which uses CMake at its core.

Build process

The  $OIFS_HOME/bin/openifs-test.sh  script can be used to build the model and run initial tests.
