Yes. Those libraries generally are not CMAQ-version dependent, except insofar as CMAQ distributed I/O requires I/O API 3.2. ---

You’ve got directory problems in your setup, possibly caused by missing/un-set _make_-variables… Your I/O API build-directory is showing up as `/3LIB/ioapi_3.1/Linux21_x86_64_gfort442` – is this correct (actually directory “/`3LIB`” directly under your filesystem root “/”? On the other hand, your netCDF include directory is showing up as “3LIB/netcdf/include” under your source directory “`/home/creator/CMAQv5.0.2/scripts/mcip/src`”, which also sounds improbable. Then when _gfortran_ can’t find these directories, it has troubles… ---
