Does GIAC use -lpng1x rather than -lpng? Or should we patch?

comment:5 Changed 6 years ago by frederichan

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.

comment:9 follow-up: Changed 6 years ago by jpflori

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.

Replying to jpflori:

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) ?
