The build on SuSe 9.0 is interesting since I received an inquiry about
whether this would work from a user in Europe.

gcc/g77 is my preferred combination of compilers anymore.

This looks fine.

All of these entry points _should_ be in libsdi.a.  Was this library
created before this point?  Were all of the entry points that are
supposed to be included in libsdi.a in fact put there?  The reason I
ask is that your problem looks the same as the one Lyndon State run
into when trying to build on Slackware 9.0.  The Unidata McIDAS inquiry
tracking system can be used to see the exchanges I had with Mark Tucker
of Lyndon about their problem:

http://www.unidata.ucar.edu/glimpsedocs/ghmcidas.html

Use lsc.vsc as the search key.

Here is the jist of what I found when allowed onto Mark's Slackware
9.0 system:

  ...

  The problem was that not all modules that are supposed to be added to
  libsdi.a were actually getting added.  The one that tripped you up was
  servutil.o.  I see no reason in the McIDAS makefile for this to happen,
  so I am stumped.
  
  In order to get things working after logging on, I did the following:
  
  cd mcidas2003/src
  touch BitUtil.o Bk11Data.o crc16.o GVAR.o m0tenoff.o MSAT.o NCDF.o nexrutil.o 
POES.o SDIConv.o SDIUtil.o TIP.o servutil.o
  make libsdi.a
  
  After remaking libsdi.a, the build proceeded normally:
  
  make mcx

  ...


>Now I've noticed that files related to functions like GetConfigInfo are
>compiled. For example GetConfigInfo is in servutil.c and serutil.o is there.
>
> mcidas2003/src> ls servutil*
>servutil.c  servutil.h  servutil.o

Right.  The problem appears to be that all of the modules that are
supposed to be added to libsdi.a are not being added.  I never figured
out why this was the case on Mark's system.

>and the one that comes with suse 9.0) 

I would stick with the gcc/g77 combination.  The problem you are seeing
is not a g77 one, but probably something with 'make'.

I strongly recommend sticking with gcc/g77.

Fedora is being updated vigorously and for free.  RedHat's enterprise
versions now cost.  We are using Fedora here at Unidata with varying
success.  McIDAS, the LDM, GEMPAK, and IDV all run fine under Fedora
Core 1.  What we have had problems with, however, is the automounter,
and the SMP kernel in some particular instances.

I think you are very close to having the SuSe build work.  If you can
figure out why all of the modules that are supposed to be put into
libsdi.a are not being put there, we will all benefit.

>Thanks for any help that anyone can provide.

No worries.
