Does GIAC use -lpng1x rather than -lpng?
Or should we patch?
during the spkg built my Makefile have this:
LIBS = -lrt -lpthread -ldl -lpng -lm -lmpfi -lmpfr -lgmp
LIBTERMCAP = -ltermcap
We probably should patch. But that's not an issue for this ticket.
Ok so let's already merge this.
Changed keywords from none to atelierpari2017
FYI, on OS X, configure finds the system libpng, looks for a main symbol in it which is not existent there, and just compiles without png support.

Up to now I think that it is not a problem to don't have png in giac from sage. giacpy or pynac are not using it.

For what it worth, for Sage Debian Live, i compile giac (from within Sage) with xcas support, by installing the system's fltk, remove the --disable flag and the nofltk-check.patch, so i guess for such a graphical use, png support could be useful.
What would be a correct patch (so that i can add it to SDL until it get fixed) ?
