When building webkitgtk-2.4.8 on a system which requires using a prefixed pkg-config (e.g. "x86_64-pc-linux-gnu-pkg-config"), there's a failure during configure: checking for LIBXML... yes checking for PANGO... yes checking for ENCHANT... yes checking for CAIRO... yes checking for GTK... yes checking for GTK_X11... no ./configure: line 18407: pkg-config: command not found configure: error: Package requirements (gtk+-x11-3.0 = ) were not met: Comparison operator but no version after package name 'gtk+-x11-3.0' in file '(command line arguments)' This is due to one place in Source/autotools/FindDependencies.m4 where "pkg-config" is used instead of "${PKG_CONFIG}". Trivial patch attached.
Created attachment 250946 [details] webkit-2.4.8-pkg-config-path.patch
The autotools build system no longer exists. (Actually, I'm pretty sure it was removed before you reported this bug!) Closing.
