I found this problem just recently and fixed the code causing it, but
it is not yet available in an addendum.

You can FTP the corrected script used in the McIDAS build, and get going
again as follows:

<login as 'mcidas'>
cd mcidas2003/src
ftp ftp.unidata.ucar.edu
  <user> anonymous
  <pass> address@hidden
  cd pub/mcidas/src
  binary
  get tclcomp.sh
  quit

Then restart your make:

make all VENDOR=-g77

The build should now proceed with no problems.

This is the file that is needed in the link process (library tk8.4 will
mean either libtk8.4.a or libtk8.4.so to the linker).  The problem was
that tclcomp.sh was not telling the linker to search the
~mcidas/mcidas2003/tk/unix directory for the library.

This is all correct.  The problem is in the routine tclcomp.sh, and the
version available in the pub/mcidas/src directory of anonymous FTP
contains the fix.

>Any help will be appreciated

Sorry for the problem.  I just cut a new full distribution and incremental
addendum with the tclcomp.sh fix.

Cheers,

Tom

Thanks for the prompt response and support.  Just tried it, and it worked like 
a champ.

Thanks again,
