Oops, I hit tab key and it posted the message before I was finished.
Lets try again.
Cool! I found a sucker (er, um, I mean a beta tester).
My first guess is it's having trouble finding the LDRAW path. That'll give
you a white screen for sure. I think I included a grey cylinder dat file
that doesn't require any other files. If that works, it's the path for sure.
Some other questions:
Did you build it, or use the executable from the zip file?
What is the exact path to the parts files?
I have something like /usr/local/ldraw/parts/4746.dat
Did you try setting the LDRAWDIR environment variable?
If your path looks like mine you could set it to:
LDRAWDIR=/usr/local/ldraw
export LDRAWDIR
But you shouldn't have to. Hmmm, did you get a path like this?
/usr/local/ldraw/ldraw/parts/4746.dat
Meanwhile, I'll have to add an error message when it can't find the file.
I can't believe there wasn't one already in the ldlite source. Perhaps I
disabled it somehow...
Good luck,
Don
