VMD-L Mailing List

I've linked current sources of VMD against Fltk 1.1.0.12b; it works fine,
you just have to have "-lfltk_forms -lfltk" in your link line. The fltk_forms
library will be built (and installed, with make install) in the same place
as the regular fltk library.

Maybe they're trying to get us to update our software? ;-)

Now, I already added the proper paths to the FLTK include and lib dirs in the Makefile, so I can't figure out what I'm doing wrong. Any idea or suggestion is welcome.
