[netCDF #JRL-687884]: Netcdf-fortran error while compiling. "configure: error: cannot compute sizeof (off_t)"

Hello,

Thank you for reaching out, and for providing the config.log files.  From the 
contents of the netCDF-Fortran config file, I suspect that the linker is not 
able to locate libnetcdf at runtime, when trying to compile the tests it uses 
to determine other aspects of the environment.  You may be able to fix this by 
specifying the LD_LIBRARY_PATH when configuring netCDF-Fortran, thusly:

    $ LD_LIBRARY_PATH='/home/raj/gcc/netcdf-c-4.7.4/codes/lib' 
CPPFLAGS='-I/home/raj/gcc/netcdf-c-4.7.4/codes/include' 
LDFLAGS='-L/home/raj/gcc/netcdf-c-4.7.4/codes/lib' ./configure 
--prefix=/home/raj/gcc/netcdf-c-4.7.4/codes

If this works, you may need to set this as a persistent environmental variable, 
in order to avoid 'missing library' errors any time you run a program which is 
linked against libnetcdf.

I hope this helps!
