pio build fail

[robert_letscher@unh_edu]

I'm attempting to port CESM 2.1.3 to my local linux cluster and receive an error during the pio build phase related to "can't open module file 'netcdf.mod' for reading at (1): no such file or directory".

pio.bldlog file is attached.

I see that it found libnetcdff.so in /usr/lib64/libnetcdff.so
it can't find file netcdf.mod - where is it on your system?
Try setting env variable NetCDF_Fortran_INCLUDE_DIR to that location.

I've located the path to netcdf.mod on my system. However I am unsure where/how to add the env variable for netcdf fortran to that directory.

I have added a line under environment_variables in my config_machines.xml file pointing to the directory containing netcdf.mod using the case sensitive 'NetCDF_Fortran...' that you mentioned as well as in all caps (to match the formatting of 'NETCDF_PATH' there). Both cause ./create_newcase to fail with an error message that states that there is a not well-formed (invalid token) at the line in config_machines.xml where I've entered to path to netcdf.mod.

See below, copied from my machine info within config_machines.xml:


<environment_variables>
<env name="OMP_STACKSIZE">256M</env>
<env name="MPI_TYPE_DEPTH">16</env>
<env name="NETCDF_PATH">/cm/shared/modulefiles/netcdf/gcc/64</env>
<env name="NetCDF_Fortran_INCLUDE_DIR">/usr/lib64/gfortran/modules</env>
</environment_variables>
<resource_limits>
<resource name="RLIMIT_STACK">-1</resource>
</resource_limits>
</machine>

I don't see any problem with what you've posted here. Please try adding the --debug flag to your create_newcase command and post the resulting error.

Thank you. I edited my config_machines.xml again for NetCDF_Fortran_INCLUDE_DIR and ran create_newcase under debug mode. This time create_newcase completed fine. BUT the pio build failed again under case.build. bldlog attached as is my config_machines.xml file. My machine is called 'marvin' and is the last machine listed in config_machines. It looks like the pio build still can't find NetCDF Fortran. On my system, there is only one netcdf installed at /netcdf/gcc/64/4.6.1. Perhaps this is netcdf_c and I also need to install netcdf_fortran?

issue was resolved after installation and build outs of netcdf-c and netcdf-fortran v4.8 on my system.
