[Met_help] help with METv1.1 gmake on Linux system

[John Halley Gotway]

ZhenCai,

Thanks for sending the compilation log.  It makes it much easier to
diagnose the problem.

It looks like the linker doesn't like your version of NetCDF for some
reason.  Since MET is written primarily in C++, it links to the C++
interface for NetCDF.  It's looking in the directory
"/disk2/hg/dzc/netcdf/lib" for two files: libnetcdf.a and libnetcdf_c++.a

First, please verify that those two files exist in that directory.

Second, it may be the case that you built NetCDF with the GNU compilers
and are building MET with the PGI compilers.  You'll need to build them
both with the same family of compilers.

Please take a look at the following excerpt from the MET Online Tutorial:
http://www.dtcenter.org/met/users/support/online_tutorial/compilation/req_libs.php

In the section, "Compiling NetCDF", it lists out which environment
variables to set to tell the NetCDF configure script which compilers to
use.  I think the following settings would work for you to build NetCDF
with the PGI compilers:

cd "directory containing NetCDF"
make clean
setenv CC  /disk2/hg/dzc/pgi716/linux86-64/7.1-6/bin/pgcc
setenv CXX /disk2/hg/dzc/pgi716/linux86-64/7.1-6/bin/pgCC
setenv FC  /disk2/hg/dzc/pgi716/linux86-64/7.1-6/bin/pgf90 or "" to
disable Fortran interface that MET doesn't use
setenv F90 /disk2/hg/dzc/pgi716/linux86-64/7.1-6/bin/pgf90 or "" to
disable Fortran interface that MET doesn't use
./configure --prefix=/disk2/hg/dzc/netcdf
make
make install

Try working on your NetCDF build, and then try rebuilding MET.

If you haven't already done so, you should probably download the latest
set of bug fixes for METv1.1.  The single tar file named
"METv1.1_patches_20090212.tar.gz" contains all of them:
http://www.dtcenter.org/met/users/support/known_issues/METv1.1/index.php

Also, since you're building on a 64-bit machines, you will likely have
trouble using BUFRLIB and PB2NC.  Here's a discussion about problems on
64-bit machines:
http://www.dtcenter.org/met/users/support/known_issues/METv1.0/met_64_bit.php

And lastly, just to let you know, METv2.0 is due to be released in the
next couple of months.  We'll send an email when it's available.

Good luck,
John Halley Gotway
