No worries.

I'm cutting to the chase....

Oops, my bad.  I didn't notice that you had included the makelog.  My
apologies!

I just figured it out.  The problem is evidently that Fedora 16 is powered by a 
Linux 3.x kernel, not a 2.x kernel.  I should have realized this earlier, but I
actually have built on a Fedora 16 system, but I never ran any GUI, so I never
noticed that 'mcwish' would not find the needed shared Tk library.

Here is what you need to do to get things working; I will update the Unidata
McIDAS distribution to include the fix in an addendum:

<as 'mcidas'>
cd ~mcidas/mcidas2009/src

-- edit the file 'tclcomp.sh' (NB: NOT 'tclcomp') and jump to line 218

   Line 218 should look like:

"Linux 2."*) RUNTIME_PATH="-Wl,-rpath,$TCL_PREFIX/lib";;

   This says for 'uname -sr' listings that look like "Linux 2." set
   RUNTIME_PATH to include the link directive '-Wl,...'  Since your
   kernel is v3.x, this line does not match, and RUNTIME_PATH does
   not get set (doh!).

   To get things working I would simply change the line to read:

Linux*) RUNTIME_PATH="-Wl,-rpath,$TCL_PREFIX/lib";;

   So, the code would look like:

# <<<<< UPC mod 20051103 - change FreeBSD entry to match all versions >>>>>
# <<<<< UPC mod 20120401 - change Linux entry to match all versions >>>>>
#
RUNTIME_PATH=
case \`uname -sr\` in
"SunOS 5."*) RUNTIME_PATH="-R $TCL_PREFIX/lib";;
Linux*) RUNTIME_PATH="-Wl,-rpath,$TCL_PREFIX/lib";;
Darwin*) RUNTIME_PATH="-Wl,-search_paths_first";;
FreeBSD*) RUNTIME_PATH="-Wl,-rpath,$TCL_PREFIX/lib";;
OSF1*) RUNTIME_PATH="-Wl,-rpath,$TCL_PREFIX/lib";;
IRIX*) RUNTIME_PATH="-Wl,-rpath,$TCL_PREFIX/lib";;
HP-UX*) RUNTIME_PATH="-Wl,+b,$TCL_PREFIX/lib";;
esac

-- after making the editing change, clobber and remake McIDAS
   (NB: don't wipe out the directory and re-populate from the
   distribution file!!!!!):

make clobber
make
make install

After doing this, mcwish should find the McIDAS-installed Tk shared
library and, therefore, run!

The reason I have not run into this problem in my Fedora 14, Fedora 15
or CentOS VMs is that they are all still running a 2.x kernel.  Evidently
Fedora 16 has moved on to v3.x.  That's what life is like on the
bleeding edge!  Another reason to switch to CentOS!!

Cheers,

Tom
