[ncl-install] NCL Ubuntu

But did you 'sudo apt-get remove ncl-ncarg'?  That should rid you of your 6.1.2 install.  Then install by your method of choice.  I guarantee if you go through the conda install process as documented, then source activate the environment, it won't conflict with 6.1.2 if you still really need it.  Be aware that anaconda or preferably miniconda will install a python environment in your home dir, so you will have to export that python environment to your path.  I do this on a per terminal basis using an alias, then source activate the ncl environment.  That way, miniconda python doesn't hijack my python environment.  Anaconda/minconda will offer you the option to let it prepend itself to your path.  I just say no here, because I have another python environment I choose to use for the time being by default.

Hi all, 
I think you might have misunderstood me since the export NCARG_ROOT did nothing at all to fix the problem and I had tried removing and re-installing but every time I do it still is giving me the 6.1.2.

I just installed the Ubuntu ncl-ncarg package on my Ubuntu laptop to see what would happen.  Surprisingly, this turned out to be a recent-ish6.3 install (on 16.10, yakkety).  It set no NCL related variables that I could find, but it did lead me to the more obvious "where in your path list does ncl show up?"  You would want the location of your 6.3 to be listed before the location of 6.1.2.  Ubuntu installed it in /usr/bin, so if you installed your 6.3.0 in /opt or /usr/local/bin, make sure that path comes before /usr/bin in your path list.

The Ubuntu install did not affect either my conda-installed ncl_stable or ncl_test that I noticed.

If you don't need 6.1.2, then I'd suggest 'sudo apt-get remove ncl" it.  If you really need both versions then you need to de-conflict the two installations.  If you use the commands that Mary gave you, you will see that your Ubuntu is trying to use the 6.1.2 version.  I have successfully used the Ubuntu installed version and a newer version in the past but I forget the mojo.    It does matter where and when you set your NCARG_ROOT.  One possible error:  assuming bash, you set it in your .bash_profile, not your .bashrc.  In this situation your login shell knows NCARG_ROOT, but no other terminal you open will.  So either don't set it in .bash_profile or have bash_profile source .bashrc as the last act in your .bash_profile.

I think also if you do the 'env' command below, I think you will find that the Ubuntu package sets some other environment variables that are similar to, but different than 'NCARG_ROOT'.  You will need to figure out how to unset those.  Easiest way is to remove 6.1.2, which I highly recommend.

Hi Mary,
I set my 
NCARG_ROOT=/usr/local/lib/NCL6.3/
but my ncl is at /usr/bin/ncl and version 6.1.2

JP,

How exactly and where are you setting NCARG_ROOT?

If you type the following at the UNIX prompt from a Terminal window, what does it report?

env | grep NCARG
which  ncl
ncl -V

If you are setting anything other than NCARG_ROOT, then uncomment these from whatever .* file in your home directory is setting them.

    Hi there,
    I am having trouble setting my NCL on my Ubuntu WSL. I keep trying export NCARG_ROOT= wherever my NCL6.3 is but it keeps thinking the NCARG_ROOT is the ncl that I sudo apt-get installed. How can I fix this?

    Thanks,

    JP Kalb
