Hi, All. An error, " Can’t find an intrinsic module named ‘ieee_arithmetic’",appeared during compiling CCTM with CMAQv5.5. And the gfortran version I used is 4.8.5. What could be the reason? The log file is attached below:
build_cctm_ddm.log.txt (419.2 KB)
Based on this stackoverflow thread and its link to gfortran documentation, the ieee_arithmetic module is available for gfortran version 5 or higher.
Hi, Christian. You are right, and thank you so much for your suggestion. I have used an older version that include bugfixes for CMAQ DDM-3D. But I have a question: if I update gfortran, will I need to reinstall netcdf and ioapi which are based on version 4.8.5?
Yes. If you update your compiler version, you will have to reinstall the netcdf and ioapi libraries before recompiling CMAQ.
