Jim,

Nuts!

/export/home/mcidas/mcidas7.7/bin?  A couple of things here:

o McIDAS gets installed so that ~mcidas/bin is where the executables get
  installed

o everything gets built in the ~/mcidasN.M/src directory (N.M -> 7.7,. 7.8,
  etc)

o you should be installing McIDAS 7.8 now

If you are installing so that the McIDAS executables are being put in
~/mcidasN.M/bin, please change to a standard install.  The standard
installation process handles everything based on the definition of the
Unix envoronment variable McINST_ROOT which should, in your case given
that the HOME directory for 'mcidas' appears to be /export/home/mcidas,
be:

McINST_ROOT=/export/home/mcidas

>setenv LD_LIBRARY_PATH 
>/usr/local/lib:/usr/openwin/lib:/usr/local/SUNWspro/lib:/usr/ccs/lib:/lib:/usr
> /lib/:/opt/SUNWmotif/lib

Do you have Sun compilers?  I thought not.  If not, then you do not need
the SUNWspro/lib directory in your LD_LIBRARY_PATH.  If yes, then why
are you trying to build with gcc/f2c?

>setenv CXX

OK, this is good if gcc is in /usr/local/bin.  NOTE, however that you do
not have /usr/local/bin in your PATH:

>set path=(/bin /usr/bin /usr/openwin/bin /opt/local/bin 
>/opt/SUNWspro/bin /usr/ccs/bin  /usr/ucb /usr/sbin /etc 
>/opt/local/tex/bin /export/home/mcidas/mcidas7.7/bin .)

So, either your PATH (path) is wrong, or you do have Sun compilers and
should use them.  Which is the case?

># MCHOME and McINST_ROOT
>setenv MCHOME $HOME
>setenv McINST_ROOT $MCHOME

This is correct as I noted above.

I changed the conditional PATH clause above effective for 7.8.  It should
now read:

# NOTE: conditional definition is only needed for C-shell users
if ( ! ${?MCPATH} ) then
  setenv MCDATA $MCHOME/workdata
  setenv MCPATH ${MCDATA}:$MCHOME/data:$MCHOME/help
  setenv MCGUI  $MCHOME/bin
  setenv MCTABLE_READ "${MCDATA}/MCTABLE.TXT;$MCHOME/data/ADDESITE.TXT"
  setenv MCTABLE_WRITE "$MCHOME/data/ADDESITE.TXT"
  setenv XCD_disp_file $MCDATA/DECOSTAT.DAT
  if ( ! ${?path} ) then
    set path=${MCGUI}
  else
    set path=(${MCGUI} $path)
  endif
endif

This was not necessary.  The distribution compressed tar file always
has all of the latest bugfixes and additions. The bugfix compressed
tar file, mcupdate.tar.Z, is made available to users who have an
existing installation and want to bring it up to current revision.

Notice how the netCDF build is trying to use c89, not gcc.  This tells me
one or both of two things:

o your PATH does not include the directory containing gcc (and f2c?)

o you had not made the environment variables active (source .cshrc)
  before starting the build

Thewse are just warnings.

OK, so this says that gcc can be found.  This is somewhat confusing given
the PATH you listed above.

c89 is a standard C compiler.  The configure process for the netCDF
portion of the build defaults to use of c89 unless you override it by
defining CC _before_ configure is run.

I am guessing that you may have added the CC CPPFLAGS, etc envirronment
definitions to your .cshrc file, but you did not make them active in
your Unix session before starting to build McIDAS.

No, it is bulndled with McIDAS.

The absolute easiest thing to do is:

1) logoff

2) log back on

3) verify that CC, CPPFLAGS, etc are set in your environment:

   env | grep CC
   env | grep CPPFLAGS
   etc.

4) if 3) is OK, then do the following:

   cd mcidas7.8/src
   make clobber
   make all

The 'make clobber' step will remove all things made with previous make
attempts.  Puts you back at a known state.

McIDAS-XCD is the component of Unidata McIDAS that contains decoders
for all of the data you can receive through the IDD.  If you want
to decode the realtime NOAAPORT data in the IDD, then you will have
to build, install, and configure McIDAS-XCD.  For reference, XCD
stands for X Conventional Decoders.

Right.  I build from home all of the time.  In fact, I am writing this email
from home.

No worries.  If you get a good, error free build and install, both of our
jobs will be easier in the future.
