 Anyone have any ideas??


Yes: note that fltk3 is still alpha, and is intended for experiments only at 
this stage, so has a few rough edges.

What you are hitting is STR #2833 http://www.fltk.org/str.php?L2833

In summary, there is a bug in fltk3's configure mechanism such that it attempts 
to build fltk's built-in PNG lib version, even if there is a system wide one 
available. (The earlier fltk variants only compile the built-in PNG lib if 
there is no system-wide one found...)

However, when building the built-in PNG, the system PNG headers get found 
first, and they are *not* compatible (too old), and Bad Things ensue.

If you can be bothered, tweaking the paths in makeinclude so that the correct 
set of PNG headers are found when building the local built-in PNG lib will 
fix this.

Or, you could try configuring with --enable-local-png as I think that might 
help...

Or, you could update your system PNG to something recent, and that should help 
to!
