Hello! I have been trying to install MPAS-CMAQ recently, and the guide recommends using MPAS7.0. However, I encountered some obstacles during the library installation process. I have already installed the following:
I tried switching to pnetcdf version 1.9.0 and PIO version 2.6.2, but encountered the same error. I look forward to your answer!

- zlib 1.2.11
- szip 2.1
- hdf5 1.10.1 (note: you mentioned 10.1 but the standard versioning for HDF5 usually includes a leading '1.', so I assume it's 1.10.1)
- pnetcdf 1.8.1
- netcdf-c 4.7.4
- netcdf-fortran 4.4.4
I tried switching to pnetcdf version 1.9.0 and PIO version 2.6.2, but encountered the same error. I look forward to your answer!
