Hi Robb,

Thanks for your help. I am still puzzled about why it was not working
earlier, but I re-compiled netcdf, udunits and ldm packages and it worked.
Thanks again,

Enils

Enils,

Here's a solution to your problem. Steve was correct about the different
versions of the compiler. I believe that there is a problem with the
decoders package using the wrong libraries that caused the problem. The
solution is to make the decoders package use the correct libraries.

Here's the steps:

The latest netCDF package builds OK on our Red Hat 9 system:

    $ make distclean
    $ uname -a
    Linux rodney.unidata.ucar.edu 2.4.20-13.7-athlon-smp #3 SMP Tue Jun 3
10:36:25 MDT 2003 i686 athlon i386 GNU/Linux
    $ cat VERSION
    3.5.1-beta13
    $ CC=/usr/bin/gcc CPPFLAGS='-DNDEBUG -Df2cFortran' CFLAGS=-O
FC=/usr/bin/g77 FFLAGS='-O -Wno-globals' CXX=/usr/bin/g++ ./configure
&>configure.log
    $ make &>make.log
    $ make test &>test.log
    $ make install
    $ less test.log # it looks OK

The UDUNITS package (minus the Perl extension) builds OK on the same system:

    $ make distclean
    $ cat VERSION
    1.12.1
    $ CPPFLAGS=-Df2cFortran CC=/usr/bin/gcc PERL= ./configure
&>configure.log
    $ make &>make.log
    $ make test &>test.log
    $ make install
    $ less test.log # it looks OK

The decoders package

    $ make distclean
    $ CPP_NETCDF=-I/home/rkambic/netcdf/netcdf-3.5.0/include
    $ LD_NETCDF="-L/home/rkambic/netcdf/netcdf-3.5.0/lib -lnetcdf"
    $ CPP_UDUNITS=-I/home/rkambic/udunits/udunits-1.12.1/include
    $ LD_UDUNITS "-L/home/rkambic/udunits/udunits-1.12.1/lib -ludunits
-ludport"

Note:
The above paths need to be corrected for you build trees. I would test the
dirs with the ls command.

    $ CC=/usr/bin/gcc ./configure &>configure.log
    $ make &>make.log
    $ make test &>test.log
    $ make install
    $ less test.log # it looks OK

If the decoders can't find the netcdf/udunits includes/libraries then look
at the configure.log to make sure that the configuration is correct.

If you still have a problem, it's possible that your PATH or
LD_LIBRARY_PATH might have to be changed.  I don't think that's the
problem though.


The compiler versions are:

    $ /usr/bin/gcc --version
    gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
    ...
    $ /usr/bin/g77 --version
    GNU Fortran (GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-5)) 3.2.2 20030222
(Red Hat Linux 3.2.2-5)
    ...
