I get the same thing.  I've found a way to keep it from core-dumping,
however.  I think you'll find that it core-dumps whenever you leave the
cursor on top of one of the menu bar buttons (i.e. the "new" button, the
"save" button, the "render" button, etc).  I think that the fault must
be caused whenever the program tries to generate little help-windows on
those buttons. (you know, the way netscape and many other programs do if
you hold the cursor over a button for a second or two?)

The solution is:  don't leave the cursor hanging about the buttons. :)

Greetings.

I'm William Hayden, the author of POV-Motif.  The problems you describe
below seem to be fairly common for certain versions of LINUX, and non
existant for others.  My Slackware distribution falls into the latter
category, so this is a tough problem for me to track down.  I do have a
workaround for it though.  Version 1.0.1 POV-Motif has a way to turn the
tool tips off.  The tool tips are little popup windows that tell what
the buttons do.  When these guys fail to load the font
schoolbook-bold-r-normal-*-12-*, they cause POV-Motif to bomb.  The
tooltips aren't something I wrote, they're a freeware library called
LiteClue that I downloaded.  I have corresponded with the author of the
package, and he and I are both puzzled as to why 1) the fonts fail to
load and 2) why a crash is the result when they fail to load.  It is
standard X code, known to work on Solaris, SunOs Hp/UX, IRIX,
AIX.......  Probably a LOT more than you wanted to know about the
problem.

To turn the tool tips off use the menu Options->Set POV-Motif
Configuration...

Set the tool tips toggle button to off.  There is no need to restart
POV-Motif, and the setting is persistant.  In a future version of
POV-Motif, with the tool tips off, I'll put help text in the status text
window at the bottom of the application.

You also mention that the buttons don't have the proper pixmaps unless
you run as root.  This is probably due to the resource file not being
where POV-Motif can find it.  Visit the POV-Motif home page again and
look at the FAQ section for help with setting this up properly.  Most
X/Motif applications have this issue during setup, so this is a failry
common problem.


thanks for your interest in POV-Motif.  Any comments/suggestions for
version 1.1 would be greatly appreciated.

Regards,

Thanx for releasing it as freeware, the big problem is that motif aint
free :/

IMHO, i'd prefer it if it used GTK, since i dont rather feel for paying
for a gui.

How about lesstif, it's free.  It's not quite done yet, it has a few
problems drawing windows properly.  But it's much better then paying the
100+ dollars for motif.

You don't have to since the precompiled binairies are statically linked
against motif!

Actually I think mr Hayden has tried with lesstif and unfortunately it didn't
work. Lesstif is nice but it still has a bit to go before it's finished.

Anyway, POV-motif is a nice front-end to POV and in some aspects it's even
better than the Win GUI it's modelled after, and then again in some aspects
it's not, I'd really like to see some auto-indentation of entered text, but
then again, you can't have everything.

Sincerely

Hans Wachtmeister

Hi.  This is William Hayden, author of POV-Motif.  Thank you for your
interest in the application.

Hans Wachtmeister responded to your post with exactly what I was going
to tell you.  POV-Motif is statically linked with the Motif libraries,
and Motif isn't required to be on your system for you to use POV-Motif. 
I urge you to give it a try!  I use it all the time in my POV-Ray work.

As for GTK, there are a number of X toolkits out there of varying
popularity and usefulness.  GTK isn't one that I'm familiar with (Gnu
Tcl/Tk I'm guessing??), but then I have mainly concentrated on
commercial X development.  That means Motif.  In addition, POV-Motif was
a LOT of code.  I only wrote about half of it.  An excellent GUI builder
tool call XDesigner wrote the lion's share of the Motif code.  Since I
could statically link in the Motif code, I didn't see that it was a
problem developing against Motif.

To address Andrew McDavid's point about Lesstif.  I tried.  I REALLY
tried to get it to work.  I too didn't want to spend $100 for Motif for
Linux.  After all, I use Solaris most of the time.  Lesstif just isn't
ready for applications of even rudimentary functionality, let alone
something like POV-Motif.  They got downright rude when I reported the
bugs I was seeing and sent them source code examples.  Go figure.  It
isn't that I object to freeware X toolkits.  Parts of the Free Widet
Foundation's library are in POV-Motif.  But I do insist that the toolkit
functions as advertised without any spurious core dumps.  Lesstif isn't
in that category, sad to say.

All this is probably way more than you wanted to know.  Again, give
POV-Motif a try.  Most people who use it don't have Motif on their
systems.  Aside from a font problem on some systems (and there is a
workaround for that) it seems to function well for most users.

I also invite you to make out a wish list for the next revision.  1.0.1
has been out for 5 months now.  I've been busy with other projects, but
I want to get a late summer release out of POV-Motif 1.1.

Once again, thanks for your interest in POV-Motif.

Regards,









William D. Hayden
