[ncl-install] Fw: help on NCL Installation

[David Brown]

It seems a bit weird that you found libx11.so in /usr/X11R6 instead of /usr/X11R6/lib. That would imply using -L/usr/X11R6 instead of -L/usr/X11R6/lib. Since you are running on a 32bit system you could make sure that the X11 library is compatible by doing:

file /usr/X11R6/libx11.so

or 

file /usr/lib/libx11.so.6.2.0

You may find that the .so versions are symbolic links to the "real" file: /usr/lib/libx11.so.6.2.0.

One thing you could try is to explicitly name the library in your link line: e.g.:

gfortran -fPIC -fnosecond-underscore -fno-range-check -O -L/usr/lib name.f -L/usr/local/ncl-5.2.1/lib -L/usr/X11R6/lib -lncarg -lncarg_gks -lncarg_c /usr/lib//libx11.so.6.2.0
