Hi Maria, It may be something as simple of adding -lmpi to your config\_cmaq.csh config\_cmaq.csh: setenv mpi\_lib “-lmpi” If this doesn’t work, please send the following information: If you are using modules on a compute server, please use the module list command to see what compiler is loaded: ```auto module list ``` If not, use the command `which mpiifort` to reveal what compiler you are using: ```auto which mpiifort ``` ---

Thank you for your reply. I applied the change that you suggested in my config\_cmaq.csh, but it didn’t work. When I typed “which mpiifort” the result is: /media/maria/Backup/intel/compilers\_and\_libraries\_2019.3.199/linux/mpi/intel64/bin/mpiifort Then, I decided to change the path in: config\_cmaq.csh: setenv MPI\_LIB\_DIR But a new error comes up: distr\_env.c:(.text+0x156): undefined reference to `ompi\_mpi\_int’ So, I suppose that the change is not in the correct environment variable. Do I have to change the path in other place? Maria ---

Hi Maria, Please try adding the following environment variable to your config\_cmaq.csh under the section case intel: ```auto setenv myLINK_FLAG "-qopenmp" ``` Liz ---

Thanks for your response. But the problems still persist after installing netcdf-c-4.6.3 and netcdf-fortran-4.4.4 following your instructions.

You have an error with specifying the MPI libraries in the link-line. Note that what is required is dependent upon which MPI implementation you are using – the MPICH implementation of MPI uses different libraries than OPENMPI (and further note that it is also dependent upon the vendor of the underlying C and Fortran libraries… ---

What’s your underlying compiler for OpenMPI? Since the I/O API is openmp-enabled (with various other programs using omp shared-memory parallelism), you need to include the appropriate OpenMP flag in your link step (-qopenmp for Intel, -fopenmp for GNU, -mp for PGI, …) ---

I have been able to successfully compile CCTM after so many manipulations of my scripts. Thanks so much for your guide. I’m available to help those facing the challenges I have faced in the course of compiling CMAQ and its related models. Cheers.
