PNETCDF not working with real.exe when using configure_new (io_form = 11)

[William.Hatheway]

I have built WRF-4.7.1 using configure_new to test out the pnetcdf io integration.

I built it using this command

    ./configure_new -x -p "oneAPI LLVM" -- -DWRF_CORE=ARW -DWRF_NESTING=BASIC -DWRF_CASE=EM_REAL -DUSE_MPI=ON -DUSE_HDF5=${HDF5_ROOT} -DUSE_JASPER=${Jasper_ROOT} 2>&1 | tee wrf_configure_new.log

when using a namelist (attached) that works with the old configuration method, that includes pnetcdf support, it cannot find the io form 11 option in real.exe which causes wrf.exe to fail.

When I change io_form to the default =2 the namelist attached works.

Is there a -DUSE command that needs to be enabled to enable pnetcdf?

Ran a test with these steps, please make sure I did it correctly

1. Install all the library files
2. clone the current github
3. gh pr checkout 2145
4. configure and compile WRF

then ran wps and real.exe and got these errors
