but that's quit obvious or I wouldn't have got to the link stage at all. I installed fltk 2, tried that example and got the problem above. I uninstalled it, installed 1.3 tried the 1.3 example with the same problems. Well, I used the fltk2.config and fltk.config respectivly. By the way, I did it on two different maschines, one running SuSE 10.0, the other 10.3. I get allways the same results. I tried different oders of libraries and object file, different ways to specify the library (-lfltk vs. /usr/local/lib/libfltk.a). I get allways the same result. I think there must be something with the library. I have never seen ld mention it when using the -t option. But ld complains when I missspell the library or corrupt it.
