These macros are not part of automake, they're maintained by the pkg-config project, whose mailing list is pkg-config at lists.freedesktop.org. You might be confused because automake does provide aclocal which is a general purpose tool for bundling macros into aclocal.m4, but that doesn't mean automake or aclocal has anything to do with their content. > Of course, one can get around this by setting the PKG_CONFIG_LIBDIR > environment variable prior to running ./configure but I think that > most people won't know that it's necessary, and it seems redundant to > me, because of the --host flag. According to the pkg-config README, the way this is supposed to work when cross compiling is to name the pkg-config script in the sysroot as $host-pkg-config to differentiate it from the pkg-config of the build machine and it should figure out the rest automatically. Maybe you need to upgrade to a later version of pkg-config. Brian

Cross compiling with pkg.m4
pkg.m4 doesn't behave in a very rational way, when configured with --host=xyzzy All the PKG_CHECK_MODULES macros continue to find the local modules, not the ones for target xyzzy.Consequently, the build fails when the compiler/linker can't find the header/library for the necessary packages. Of course, one can get around this by setting the PKG_CONFIG_LIBDIR environment variable prior to running ./configure but I think that most people won't know that it's necessary, and it seems redundant to me, because of the --host flag. Shouldn't PKG_CONFIG_* find only packages pertaining to the target architecture?
