I figure we should put something in the README.cairo file
in the OSX section for this.
Not sure what to write though.
I've spent the last few hours just trying to get cairo
to build from source (instead of using Mac Ports),
and that seems to give better results for FLTK.
There are some nice Mac specific build instructions for
cairo here:
http://cairographics.org/end_to_end_build_for_mac_os_x/
..but these are a bit out of date and perhaps incomplete;
I found I had to change several things, and had to add
some extra environment settings not shown in those instructions
to get pkg-config to work right (a tool I know little about,
but appreciate its purpose)
I've gotten FLTK to build with cairo this way, as the cairo-quartz.h
file is now found OK.
It does get through building FLTK, but dies when it tries to link
the cairo test program:
Linking cairo_test...
Undefined symbols:
"_GetWindowPort", referenced from:
Fl::cairo_make_current(void*) in libfltk_cairo.a(Fl_Cairo.o)
ld: symbol(s) not found
Apparently this is because GetWindowPort is a deprecated Carbon
call that no longer exists.. at least not on my 10.6.8 build system.
Sniffing the web, found another app with a similar issue:
http://code.google.com/p/ogld/issues/detail?id=4
.. and they seem to say GetWindowPort has been removed, and that there's
no simple cocoa equivalent, so they are investigating retooling for
cocoa.
