This sounds suspiciously like bug #1949 http://www.fltk.org/str.php?L1949 There's an issue in the configure script where it fails to set config.h so that it knows to handle the alpha channel in PNG images. The STR discusses the fix, but the quick'n'dirty fix is to edit the config.h in your fltk build and change the lines as follows: /* #undef HAVE_PNG_GET_VALID */ /* #undef HAVE_PNG_SET_TRNS_TO_ALPHA */ #define HAVE_PNG_GET_VALID 1 #define HAVE_PNG_SET_TRNS_TO_ALPHA 1 Then rebuild your fltk lib and the PNG's should all work nicely.
