Hi -- again to clarify: this program still doesn't act as
ImageMagick's "display" command or anything -- it is only a POC that
"one can easily display images output by MPLib using Qt". Just do
"./guitest" and you'll see a triangle stroked by a rotated elliptical
pen -- that's all. If you want to see some other picture displayed,
you'll have to alter the MP_COMMAND lines within the CPP.

Sorry if I raised too many expectations... :-( I really was just
excited that I could simply redirect the output of MPLib to Qt.

I still have some problem with getting my program to act like the
regular mpost. I'll work on that.

Sure -- the -L . tells the compiler to include the current directory
while searching for libraries to link against.

BTW @Taco/Hans: can I have some help on that shared lib front please?
