How to setup ncgen?

[duckweed]

hi,
when i run ncgen,the error:
ncgen: Command not found.

when i run :
which ncdump
ncdump: Command not found.
which ncgen
ncgen: Command not found.

however my linux server has an netcdf library,and it has ncdump and ncgen files
how to solve it?
thanks a lot!

Code: Select all

PATH=$PATH:home/thingumajig/netcdf_dir/bin         
export PATH

home/thingumajig/netcdf_dir/bin is the dir where your ncdump/ncgen are, so modify the name according to where you put netcdf.
Add these lines to your:

Code: Select all

$HOME/.profile

if you are a ksh or sh user

Code: Select all

$HOME/.bashrc

if you are a bash user
export PATH is probably already in there. In that case, just add the first line.
then from the command line

Code: Select all

source .profile (or .bashrc)

and try again with ncdump

ncdump and ncgen are programs from the NetCDF library and not ROMS You need to find out where are those programs installed in you computer. There is plenty information in the wiki and in this forum about the NetCDF library.

You need to do some reading. You need to understand NetCDF pretty well before attempting to runs ROMS.
