This script install_openfoam_6_impi2018_gcc82.sh needs more setup before being called, or need to setup GCC path to be used. Following the tutorial of OpenFoam, it appears that running this command "azhpc-run -u hpcuser apps/openfoam_org/install_openfoam_6_impi2018_gcc82.sh" will generate error

make: gcc: Command not found
