[SupportPlaza #PDS-980326]: broken link on ldm-mcidas pages

Hi Susan,

Yea, the McIDAS/ldm-mcidas support for MacOS-X was marginal in 2004.

Good thought!  But, it wouldn't have mattered.

Also a good thought.  Dave Dempsey of SFSU is a great guy and very
approachable for things like this.  Dave used to be a member of
the Unidata Users Committee.

There is nothing wrong with using binaries especially for packages like
GEMPAK since it requires that one have Motif installed for linking

Interesting.  Have you sent in an inquiry regarding this problem?  If
not, you should:  address@hidden

This is not needed for the partial build of ldm-mcidas.  Here is what
I did:

1) download the 3.6.1 version of netCDF:

<as 'ldm'>
setenv CC gcc
setenv CFLAGS -O
setenv CPPFLAGS '-DNDEBUG -Df2cFortran'
setenv CPP_LDM -I/Users/ldm/include
setenv LD_LDM '-L/Users/ldm/lib -lldm'
setenv CPP_MCIDAS /Users/mcidas/inc
setenv LD_MCIDAS '-L/Users/mcidas/lib -lmcidas'
setenv CPP_NETCDF=/Users/ldm/netcdf/include
setenv LD_NETCDF '-L/Users/ldm/netcdf/lib -lnetcdf'
setenv LD_X11 '-L/usr/X11R6/lib -lX11'
setenv FC /usr/bin/g77

Note that the definitions for CPP_MCIDAS, LD_MCIDAS, and FC point to
non-existent things.

cd ~
mkdir netcdf
cd netcdf
ftp ftp.unidata.ucar.edu
  <user> anonymous
  <pass> address@hidden
  cd pub/netcdf
  get netcdf-3.6.1.tar.gz

tar xvzf netcdf-3.6.1.tar.gz

cd netcdf-3.6.1/src
make install
cd ~/netcdf
ln -s netcdf3.6.1 runtime
ln -s runtime/* .

cd ~/ldm-mcidas/ldm-mcidas-2004/src
-- failure, but not to worry

cd decode
make pnga2area
./pnga2area        <- just to make sure that it runs

cp pnga2area ~/decoders

So, you now have a 'pnga2area' decoder in your /Users/ldm/decoders
directory.  You should be able to quickly determine if this executable
works for you... just setup your LDM to ingest any/all of the
UNIWISC (aka MCIDAS), FNEXRAD, or NIMAGE feeds; use the pqact.gempak_xxxxx
pattern-action files that specify decoding of the imagery using
pnga2area; and stop/restart your LDM

Please let me know if the decoder is working for you now.
