Jimmy,

Fine, and you?

Sounds like you have made a lot of progress.  I am curious; what are
the major differences that you found between CIRA's McIDAS (RAMSDIS)
and ours?

First off, why are you running two different versions of Linux?  It seems
to me that running a single version of an operating system would be easier
for you to support.  The error report below reinforces this.

All of your problems at this point relate to 'decoder.c'.  This routine
is only used on systems that are running the SSEC satellite ingest
software (direct GOES ingest; requires special hardware, a large dish,
etc.).  Since you are not running this system, the simplest thing for
you to do is to create the 'decoder' executable so your build can continue.

>I do not know what that mean :(, so, In this way I depend enterly from

I logged onto a user's system that is running Slackware to troubleshoot
this problem, but I could not come up with a fix.  My recommendation
for you is:

<login as 'mcidas'>
cd mcidas7.5/src
touch decoder
chmod +x decoder
make mcx

This should get the build going again.  Again, since 'decoder' will not be
used, having an empty executable should do no harm.

You are welcome.
