Re: Problems with NCARG

Hi David,

I friend of my told me about an answer in NCL's FAQ section, more
specifically:

http://www.ncl.ucar.edu/FAQ/#misc_003

At home, on my Fedora 8 installation, the suggestions given in this link
works perfectly. I could compile MM5's TERRAIN program without problem. But,
there is a issue not covered by this answer: the problem with PNG library.
This problem was solved when I included -lpng in the list of libraries used
in compilation (in fact, I saw something related with PNG library on site
about building NCL from source). I suggest include a tip about -lpng in this
same answer to make it more complete.

At work, the same didn't happen. I'm using Fedora 10 and even including
-lgfortran it continues giving undefined references related with
'_gfortran.....'. The problem with PNG library didn't happen because -lpng
did work.

It appears that newer libraries provided by Fedora 10 aren't compatible with
NCL/NCARG precompiled version.

I think that I'll have to compile NCARG with intel compiler in order to
compile successfully.

Best regards,

Mateus
