For my $0.02, I don't believe that including graphics in libpari is an acceptable idea. I have just spent an entire afternoon trying and failing to build a program that links against libpari (at version 2.2.8) and doesn't use any graphics whatsoever. No matter what loader flags I pass, it fails with:
/usr/local/lib/libpari.so: undefined reference to `plot_outfile_set' /usr/local/lib/libpari.so: undefined reference to `set_pointsize' /usr/local/lib/libpari.so: undefined reference to `rectdraw0' /usr/local/lib/libpari.so: undefined reference to `term_set' /usr/local/lib/libpari.so: undefined reference to `PARI_get_plot' collect2: ld returned 1 exit statusIf I wanted graphics, I'd write the program to call a graphics library on its own. Why should I have to go through some torture related to portplot.o? Am I condemned not to be able to link non-graphical programs against libpari so some hypothetical developer who wants to use graphics but only knows the pari overlays - get real!
