Hello users,

I am new to compiling programs so sorry if some questions might seem too basic to some of you.

I looked into MPAS manual and user guide and read through the instructions provided there but some matters regarding building the prerequisites libraries are not still clear for me:

1) When building HDF5, do I need to enable it to be parallel?

2) Do I need to do the same for NetCDF?

3) Should I install PnetCDF before NetCDF and then use the --enable-pnetcdf during the configuration process? Or just build NetCDF "normally" and build Pnetcdf afterwards?

4) Do I need to use the same compilers for installing all libraries? I mean, for example, can I install Zlib with gcc and then pnetcdf with Mpicc?


Thanks for your attention!
 
All good questions. If you take a look at slide number 15 from this PDF Slide deck from the MAPS Tutorial page (Downloading and Compiling MPAS).

Notably the iolib_installation.sh script located at http://www2.mmm.ucar.edu/people/duda/files/mpas/sources/. It walks through how we install PIO 2.x with HDF5 support (and all the flags needed for each library). I normally use it as a guide, rather than running it.

Hope that helps, and let me know if you have any questions with it!
 
I was able to install all libraries. I am currently facing some issues for installing the MPAS regarding the PIO library, but it is been addressed on another user's post: https://forum.mmm.ucar.edu/phpBB3/viewtopic.php?f=10&t=10115

Thank you!
