  • Subject: [netCDF #HGO-285844]: fortran library fails to compile with "cannot compute sizeof (off_t)"
  • Date: Mon, 29 Jul 2024 15:55:56 -0600
From the following, it appears that the error is related to the linker not 
being able to find libnetcdf.so.19 at runtime.  This can be controlled by 
setting the `LD_LIBRARY_PATH` environmental variable to the location of 
`libnetcdf.so.19`.  From the information proviced, I believe this is likely 
`/work2/noaa/co2/sbasu/packages/netcdf-c/4.9.2/lib`, but you may need to 
double-check that the library file in-fact exists in this location.

I hope this helps, have a good day,
