What error message do you get in this case?

Note that for kit executables you must generally link
against the stub library *in addition* to the main library,
not instead of it.

Also the order is important: the tcl stub library must be listed
after any extension libraries that use Tcl (including Tk!) if they
were compiled with -DUSE_TCL_STUBS.

libtk will depend either on libtclstub or libtcl, depending
on how it was compiled.  libtkstub depends on libtclstub.
libtcl depends only on system libraries.

If you put libtk, libtkstub, libtcl, and libtclstub towards the
end of the link line -- after extension libraries but before
system libraries like libm, libdl, libX11, etc. -- in that order,
it should link correctly no matter how things were compiled.
