Tom,

Please let me know when port 503 is opened so I can give remote
access a try.  Also, if you decided to transfer the GINI images
to the server/LDM machine, the setup for ADDE access to the
images will need to be updated.

Which Linux (RedHat, Debian, Mandrake, SuSe, etc.)?  Which version?

If your version of Linux is "modern" (like RedHat 6.x), tclconfig
should not have to be run.

The correct order is:

o make sure CC is correctly defined if it is defined at all as an
  environment variable

o make all

If you have any portion of a previous build attempt (like you do now),
then do:

cd mcidas7.6/src
make clobber
make all

>I went back and ran tclcomp again, make all. It said there

tclcomp is run by make from the McIDAS makefile.  In older versions
of Linux (RedHat and Debian), one had to run tclconfig first.  The
need for this went away in RedHat Linux with version 5.2, and it
is definitely gone with 6.x (I have done this on 6.0, 6.1, and 6.2
on my machine at home).

Hmm...  I always put the static f2c library in the /usr/local/lib and
then set my LD_LIBRARY_PATH with /usr/local/lib as the first library
directory to be searched.  The reason for this is that the shared f2c
library does not contain the MAIN__ entry point.  If you only have the
static f2c library in /usr/lib, then there is no reason to even have a
/usr/local/lib or to define LD_LIBRARY_PATH.

One thing that may be going on here is the possibility of you not having
a correct version of f2c, f2c.h, and libf2c.a.  If you are running on
a version of Linux that uses the latest version of libc, then older
versions of f2c, etc. will not work.  They don't core dump or anything;
they just produce 0-length object modules.  When it comes time to start
linking applications, the link fails.  I make the correct versions
of f2c available in the unix/760/fortran/RedHat6.x directory.  Were you
using these?  If so (again) what version of Linux are you using?

No problem.

re: on RedHat 6.x, tclconfig should not have to be run.
