[STR New] Link: http://www.fltk.org/str.php?L1949 Version: 1.3-current OK, I think there's something awry in configure. Or perhaps more likely I just don't get it... Anyway, the configure script tests for png_set_tRNS_to_alpha around line 8181, but having found it, it defines HAVE_LIBPNG 1 (which is tested and set again later.) This code should *probably* set HAVE_PNG_SET_TRNS_TO_ALPHA at this point as well, or perhaps instead... As far as I can see, we never ever test for or set HAVE_PNG_GET_VALID anywhere in configure, so this will always be broken in the code - we either have to modify Fl_PNG_Image.cxx not to depend on HAVE_PNG_GET_VALID, or we just always set it in config.h. Either works for me, but the current pattern does not... Also, if we have selected the local-png lib, either explicitly or as a fallback, then configure must set HAVE_PNG_SET_TRNS_TO_ALPHA etc. itself, since we know, without testing, that the built-in png lib does provide that capability.
