Cairo's pkg-config not provides the -lXrender and -lX11 depends. Refer: https://bugzilla.flock.com/show_bug.cgi?id=7381 I don't know what's the problem, but when i compile the Flock with --enable-system-cairo, it will be failed with missing reference to -lX11 and -lXrender. The developer team of Flock says it's a missing -lXrender -lX11 references. Please fix it, or push it into upstream.
Yes it does. This is an issue with flock. pkg-config --libs cairo-xlib-xrender You'll see the proper output.
