Re: can not import Ngl

Hi Saulo,

It looks like the gfortran library didn't get pulled in when it did the build.

Did you set the F2CLIBS (and possibly the F2CLIBS_PREFIX) environment variable?

setenv F2CLIBS gfortran

or

export F2CLIBS=gfortran

Also, if this is in a non-standard location, you may need F2CLIBS_PREFIX to point to the location of libgfortran.so.

For more information, please see:
