[ncl-install] Problems with NCARG

Mon Apr 6 09:55:45 MDT 2009

Mateus,

I will include mention of the PNG in the below FAQ. Thanks for pointing
this out.

As for your "_gfortran" symbol problem, this has to do with you using
a different version of gfortran than what NCAR Graphics was compiled
with. You appear to be using 4.3, and the largest version we have is
4.2 on some systems, and 4.1 on others.

I've included a "libgfortran.412.a" which is the "libgfortran.a"
file that is included with gfortran 4.1.2. I renamed it to avoid
clashing with your own libgfortran.

Try linking this file in when you do the final link of
your program:

   gfortran .... -lpng -lz ... libgfortran.412.a

or better:

   gfortran .... -lpng -lz -L/path/to/libgfortran.412.a -lgfortran.412
