[ncl-talk] Using NetCDF with WRAPIT

[Rick Brownrigg]

Hi Harry,

I don't know for certain. It really looks like the compiler is not finding
the netcdf header, and needs the equivalent of a -I/usr/local/include
option. As you point out, WRAPIT doesn't accept that (seems like an
oversight to me).

I presume you are using gfortran?  It manual states: "The gfortran compiler
currently does not make use of any environment variables to control its
operation above and beyond those that affect the operation of gcc"

With that, you might try setting CPATH:

export CPATH=/usr/local/include

Other than that, you might try running WRAPIT with the -d switch. This will
show the build commands and not delete temporary outputs. From there you
might be able to manually fix-up and run the appropriate build commands.

Wish I had a better answer...
Rick
