Hi Mary,<br><br>With this file the MM5's TERRAIN program works perfectly, compiling it with intel compiler.<br><br>Mary, if I compile only NCARG and installing it in the same directory where NCL/NCARG pre-compiled files were installed, NCL functioning will be prejudiced?<br>
<br>I ask it because when I compile NCARG only (I made it with intel compiler) and link a compilation line to this new NCARG (put into a different directory), I haven't any error messages.<br><br>Best regards,<br><br>

Mateus,<br>
<br>
I will include mention of the PNG in the below FAQ. Thanks for pointing<br>
this out.<br>
<br>
As for your "_gfortran" symbol problem, this has to do with you using<br>
a different version of gfortran than what NCAR Graphics was compiled<br>
with. You appear to be using 4.3, and the largest version we have is<br>
4.2 on some systems, and 4.1 on others.<br>
<br>
I've included a "libgfortran.412.a" which is the "libgfortran.a"<br>
file that is included with gfortran 4.1.2. I renamed it to avoid<br>
clashing with your own libgfortran.<br>
<br>
Try linking this file in when you do the final link of<br>
your program:<br>
<br>
gfortran .... -lpng -lz ... libgfortran.412.a<br>
<br>
or better:<br>
<br>
gfortran .... -lpng -lz -L/path/to/libgfortran.412.a -lgfortran.412<br><font color="#888888">

Hi David,<br>
<br>
I friend of my told me about an answer in NCL's FAQ section, more<br>
specifically:<br>
<br>
<a href="http://www.ncl.ucar.edu/FAQ/#misc_003" target="_blank">http://www.ncl.ucar.edu/FAQ/#misc_003</a><br>
<br>
At home, on my Fedora 8 installation, the suggestions given in this link<br>
works perfectly. I could compile MM5's TERRAIN program without problem. But,<br>
there is a issue not covered by this answer: the problem with PNG library.<br>
This problem was solved when I included -lpng in the list of libraries used<br>
in compilation (in fact, I saw something related with PNG library on site<br>
about building NCL from source). I suggest include a tip about -lpng in this<br>
same answer to make it more complete.<br>
<br>
At work, the same didn't happen. I'm using Fedora 10 and even including<br>
-lgfortran it continues giving undefined references related with<br>
'_gfortran.....'. The problem with PNG library didn't happen because -lpng<br>
did work.<br>
<br>
It appears that newer libraries provided by Fedora 10 aren't compatible with<br>
NCL/NCARG precompiled version.<br>
<br>
I think that I'll have to compile NCARG with intel compiler in order to<br>
compile successfully.<br>
<br>
Best regards,<br>
<br>
Mateus<br>

Hi Mateus,<br>
<br>
Mary Haley is really the expert on compiling using other compilers such as<br>
the Intel compilers on Linux. She is on vacation for the next week.<br>
<br>
I don't really know the answers to your questions, but one question have is<br>
do you get any of these linking errors if you try to compile a<br>
a simple C or Fortran example program just using the system compilers.<br>

I'm trying to compile MM5 model with NCARG using NCL/NCARG binaries, but<br>
I'm getting the following errors when I compile MM5's TERRAIN program:<br>
<br>
a lot of undefined references to '_gfortran.....<br>
<br>
please see below:<br>
<br>

<br>
and problems with libpng<br>

<br>
I have installed the following package in fedora 10:<br>
libpng.1.2.35-1.fc10<br>
<br>
It seems that because I'm using intel compiler with MM5, it isn't working<br>
with libraries compiled with other compilers. My questions are:<br>
<br>
1) Can I compile NCAR Graphics with intel compiler and install it above<br>
the files provided with NCL/NCARG binaries download from Earth System Grid<br>
site? Could this procedure affect the functioning of NCL?<br>
<br>
2) In the case of png libraries, can this error be associated with the<br>
compilation with other compiler instead of intel's?<br>
<br>
<br>
Best regards,<br>
