Mark,

What was missing from this was the fact that you are using the Slackware
not RedHat.  This turns out to be the problem.

>> gcc --version
>gcc (GCC) 3.2.2
 ...

This is the same as our RedHat 9.0 version.

>> g77 --version

Ditto on g77.

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

If you check the makelog file you will see that I first ran 'make
all'.  I killed that after remember ing that you were only trying to
build McIDAS-X and not both McIDAS-X and -XCD.

I did not do a 'make install' since I thought you might like to poke
around for a bit before proceeding.

This is the mystery.  For some unknown reason, libsdi.a was not getting
fully populated by modules that are sepecifically set to be included in
it by the makefile.  I will have to chalk this one up to something
strange with Slackware since I have built on RedHat 7.3, 8.0, and 9.0
with absolutely no problems.

I was incorrect in my original thoughts.  The library that was not
getting fully updated was libsdi.a.

That should go smoothly.  I just built on a brand new FreeBSD 4.8
machine an the Universidad Federal do Rio de Janeiro last night.  That
machine set a new speed record for a full McIDAS build: 5 minutes and
34 seconds.

Cheers,

Tom

I jumped to the details without stating the obvious (from this end).  Sorry
about that.

I could not see any reason for it as well.

I appreciate that.

Very strange.  I've always had better success building software from source on
Slackware than any version of RedHat.  It looks like RedHat uses make version
3.79 where Slackware is using 3.80.  I'm not sure if that is actually the
problem but it seems to be a likely source.

I'll see what our dual 1.4ghz PIII can do.

Thanks for your help with this.
