Well, OpenMotif is free to use with systems with Licenses similar
to Linux. I`m not sure how "True Unix" is licensed.

Anyway, the answer is yes and no. Like that?

Zero first why not run linux on another computer with linux on
it and run motif off of it ? No doubt you thank yourself for
having a linux box later!

IE X -indirect linuxhost

would even offer a GDM (gnome) icon dispay of all X hosts
offering dipslays on your network

Personally, I like system like you have, but am hoping they
become a little more linux friendly.

BUT - there is an easier way !

-------------------------------------------------------

First. Installing shared libraries isn`t a terrible task. However you will likely run into the problem that the shared libs
are linked against a libc you don`t have.

WAIIT. But remember what chroot is FOR!

In other words, you can run two libc. Not great for a distributed solution.

So, in that way, you don`t even start thinking about putting
new files in with old files.

Elsewise,

It might be allot of work, but you can "somehow" do it, if it is
somehting you need done.

Often code is marked up to link with a library it doesn`t strictly need. You can change the "libXsomthing" to your
version and see if any functions pop up as missing when you
compile. If there are, but not too many, you might have a
workaround there.

see docs.sun.com
for a good explination of what library versioning is
"supposed to" mean. You see if you read it that linux
far too often makes new incompatible libs.

OpenMotif is offered as CVS. If you have both branches there are
cvs tools that can merge branches. That may be helpfull.
