configure.ac patch

The configure script of pkg-config tries to use pkg-config to locate GLib. The problem is that it immediately tries "pkg-config"; it should first try "${host}-pkg-config", in case pkg-config is being cross-compiled, to pick up GLib in the sysroot and not the one in the build system.

Note: ${host}-pkg-config is normally set up by the distribution to wrap pkg-config via PKG_CONFIG_SYSROOT_DIR.
Comment 1 Dan Nicholson 2013-01-16 15:30:36 UTC
Good catch. I think the more appropriate autoconf way to handle this would be to change the check to:

AC_CHECK_TOOL([PKG_CONFIG], [pkg-config], [])

Can you try that out?
Comment 2 Ambroz Bizjak 2013-01-16 21:36:48 UTC
Yes, this one works too, I've tested both cross-compile and native.
Comment 3 Dan Nicholson 2013-01-17 13:40:55 UTC
Thanks. I ended up checking in something different, which was just to use PKG_CHECK_MODULES from the in-tree pkg.m4. That will allow our glib check to work exactly the same way as projects using pkg-config. This includes using AC_PATH_TOOL for pkg-config, which will check for $host-pkg-config if you pass --host to configure.

Fixed in 7867cbd. Please report if this doesn't work for you.
