To build everything (with Fortran HLI, but try to be reasonable with the number of parallel threads 
, and do understand that the fortran HLI might be not fully working as I have a few commits to be pushed and DD is being updated/fixed, even if I usually don't ):
make -j16 install
Through the installer
Set the following environment before calling make (not tested recentlyplease adapt IMAS_HOME and SITEHOSTCONFIG to your local need):
export IMAS_HOME=/home/ITER/hoeneno/test-install
export IMAS_VERSION=improvement/new_low_level_rebased_3.1618.0_structure_gen
export UAL_VERSION=improvement/develop_new_low_level
export IMAS_CPPMAJOR=no3
export IMAS_PYTHONSITEHOSTCONFIG=./site-config/Makefile.ITER.HPC.CentOS-5.5
export IMAS_CPP=no
export IMAS_JAVA=no
export IMAS_MATLAB=no
export IMAS_G95=no
export IMAS_IFORT=no
export IMAS_PYTHON=no
export IMAS_PYTHON2=no
export IMAS_PYTHON3=no
export JAVA=no
And on the Gateway (UDA deployment is still work-in-progress at ITER) you need to load proper MDSplus and UDA versions:
module switch mdsplus/alpha
module use /afs/eufus.eu/user/g/g2jhollo/privatemodules
module load uda/develop
Building the tests
We have hand-made Fortran test programs
