Ok, but still, it should be more robust when things are not set up properly. >> It seems to me that the right thing in this case (no host-prefix >> tool is found) is simply to act as if pkg-config was not present at >> all, instead of using the non-host-prefixed version. > > Well, it does give you a warning... perhaps the warning should > default to being fatal, but it's basically the same situation as any > other missing cross-tool (e.g. if you had a cross gcc but no cross > ld). autoconf currently stumbles on regardless, in the hope that > your non-cross (build-arch) tool I dunno, pkg-config is different, I think -- unlike a missing compiler or linker, a missing pkg-config often simply means "you can't use any libraries for which pkg-config is required", and missing libraries [etc] is an issue which configure scripts are often prepared. So the "pkg-config missing" => "fatal error" decision is really something that should be left left to the configure script, not embedded in the pkg-config autoconf macros. However, the current state, where it pretends pkg-config is present, when it really isn't in a useful way, just fools the configure script into doing the wrong thing. [For very important libraries, I often write the library test twice, once with pkg-config, and once using traditional autoconf methods to handle the no-pkg-config case.] AFAICT, the easiest way to handle all this is just to make a missing cross-pkg-config look like a missing pkg-config to the configure script. Then whatever logic the script may have for detecting the "not pkg-config at all" case, will do the right thing for the cross case too.
