I think that PyNGL should build fairly well on a Linux system if you already have NCL installed. If you have "libX11.so", that is probably enough.
Here are the bare minimum instructions that I think you need to build PyNGL on your system:
1. Install NCL
You already have NCL installed, so make sure it is working. First make sure NCARG_ROOT is set:
printenv NCARG_ROOT
and then try typing:
ncl -V
This should report "5.2.1".
To further test NCL and see if NCL and X11 are working, type:
ng4ex xy01n -clean
This should pop up an X11 window with an XY plot. Click on this with your left-mouse button and it will go away.
2. Download the PyNGL-1.3.1 source code.
3. Set environment variables.
Before you try building PyNGL, make sure you do NOT have the HAS_CAIRO environment variable set. This will make PyNGL think you want to add cairo support, which requires a bunch of additional libraries.
Since NCL was likely built with gfortran, you will need to help the PyNGL installation find your gfortran library. To do this, set these two environment variables:
setenv F2CLIBS gfortran
setenv F2CLIBS_PREFIX /path/to/gfortran/libraries
On one of my LINUX boxes, I had to set F2CLIBS_PREFIX as follows:
setenv F2CLIBS_PREFIX /usr/lib/gcc/i386-redhat-linux/4.1.1
4. Build PyNGL
Try building PyNGL with:
python setup.py install
To test, cd somewhere away from the PyNGL-1.3.1 directory and type:
python
import Ngl
If any of this gives you problems, it helps if you can send me the output from the commands.
Thanks, and good luck,
