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

[Douglas Orr]

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...
