Old neural pathways are starting to light up again. I question whether there should in fact be any "checking for Xpm" configuration test in groff for the Xpm library or for the SHAPE extension client library interface (which is in Xext). The reason is that the groff code doesn't use these interfaces or symbols. gxditview should link and run just fine on a libXpm-free system with no SHAPE extension support (client- _or_ server-side). It sounds like one of AIX's versions of the standard X11 libraries links to these (my money's on Xaw, a popular site for vendor extensions since its defaults are so minimalistic and ugly). I don't know anything about how linking on AIX works. I'm vaguely aware that, on many Unix systems historically, shared objects and dynamic linking _don't_ work all that well. I gather libtool is the GNU solution to this problem. But groff doesn't use libtool. Another solution, albeit one that is GNU/Linux-centric as far as I know, is pkg-config. That's handy and easy to use, but...not available on AIX? Unless you have an Automake-friendly suggestion for how to easily get AIX to report dependencies of its own X libraries, I propose to make this another caveat: on AIX, you must build "--without-x". Any advice? Regards, Branden
