Re: [ferret_users] Ferret: accessing external functions

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Pascale,
The external functions are included in the "Ferret Executables" tar 
file,  ftp://www.ferret.noaa.gov/pub/linux_rh9/fer_executables.tar.Z, or 
the equivalent one for linux RedHat 7.

They are installed by the Finstall script, and the environment variable 
FER_EXTERNAL_FUNCTIONS is described in the installation guide, at 
http://ferret.pmel.noaa.gov/Ferret/Downloads/ferret_installation_and_update_guide_v550.html#Special_Environment_Variables

Please take a look at this and let us know if there still seems to be 
any problem.
