===============================================================

I think you'll describing a problem other people have had...

I had sent the following email to mailing list last week but
have yet to see it appear.  (It is sort of a history of
the init.tcl problem with suggested solutions type of
thing.)

I hope this helps...

Deja vu...

(I was hunting thru the mailing list archive for a solution
to my own install problems and I happened upon you post...
Hmmmm.... I said to myself "Boy! I know I've seen another
post with this very same problem?"  And so I had...)

The following are excerpts from other swarm-support posts
that (to me) seemed related to your problem...  I hope they
help...

Hi, all

I have problem running program examples with the following
error messages:

Cannot find a usable init.tcl in the following directories:
/usr2/opt/apps/lib/tcl7.6 ...
this probably means that Tcl wasn't install properly

while executing
"error $msg"

This is because tcl can't find the libraries. Supposedly,
someone told Tcl, during compilation probably, that it 
would find its library files in /usr2/opt/apps/lib/tcl7.6 or
somesuch.

You can fix this by first finding those libraries (a 
find / -name init.tcl -print should do the trick), then
setting the environment variable TCL_LIBRARY equal to the
path where you found that file. The same should probably
be done for Tk.

Dear Peter,

I hade exactly the same problem (using swarm in a Linux box,
with bash shell).  You have to put .profile file in your
home directory (it will be excuted at login time).

The contents of the file are (useful only for the bash
shell):

TK_LIBRARY=/home/your_name/the_dir_where_you_have_swarm/lib
export TK_LIBRARY
TCL_LIBRARY=/home/your_name/the_dir_where_you_have_swarm/lib
export TCL_LIBRARY

In my liux box, this is

TK_LIBRARY=/home/terna/swarm/swarm/lib
export TK_LIBRARY
TCL_LIBRARY=/home/terna/swarm/swarm/lib
export TCL_LIBRARY

I hope this help will be useful. Pietro

Thanks Glen,

After I set TCL_LIBRARY and TK_LIBRARY paths, the examples
ran.

Thanks for other's responses as well.

Long suffering of Redhat 4.1 user with tcl7.6/tk4.2

[ Ken: This post is quite long so I didn't include it here,
however Mr. Johnson did encounter a similar while trying to
get Swarm up and going... ]

error: TkExtra (instance)
Can't find a usable init.tcl in the following directories: 
/usr/local/lib/tcl7.5 ./lib/tcl7.5 //tcl7.5/library
/swarmapps/library
This probably means that Tcl wasn't installed properly.

This I'm not sure about, but it does have something to do
with your tcl installation. If you've installed your own
tcl7.6 and tk4.2, the stuff will all be below /usr/local (If
you used the defaults). Problem is, you've probably still
got the original redhat installation in there, which goes in
/usr/lib/tcl* or /usr/lib/tk*. Try running the command 

locate init.tcl

and see how many you have and where they are. 

Hope this helps!

Hi,

I don't know if anyone got back to you on this already, but
I can probably comment on the binary install a little.

There are copies of the appropriate *.tcl and include files
included in $SWARMHOME/lib and $SWARMHOME/include that are
appropriate to the tcl/tk code that's baked into Swarm.x
(the mother of all executables). You need to set your
environment variables to point there as indicated in the
readme files or you'll get the sorts of runtime errors you
saw. (I don't have them handy, but I think it's TK_LIBRARY,
TCL_LIBRARY, and maybe BLT_LIBRARY?)

Since these values are appropriate for running the swarm
binaries that already have particular versions baked into
them, so they may need to be set different from values
you're currently using before launching Swarm... you might
want some sort of a shell that sets them specially, if you
have conflicts...

-Doug
