I have the same issue as in this already closed STR: #2805: png_set_longjmp_fn not found inmac lion (xcode 4)
The difference is, I am using NetBSD and the current 1.3.x r9382. So, the issue is not fixed by switching to the current libpng 1.5.10 and the error is not platform dependent. It compiles and links if I comment out the call to setjmp() in FlPNG_Image::load_png_() in Fl_PNG_Image.cxx. _______________________________________________ fltk-bugs mailing list fltk-bugs@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-bugs
