use the cairo-xlib-xrender pkg-config file (1.93 KB, patch)

Description David King 2014-10-13 12:47:43 UTC 
The fix to bug 736817 introduced a dependency on cairo-xlib-xrender (and eventually, libXrender), but did not explicitly link with it. This causes problems with some linkers, such as gold, as the implicit linking to cairo via GTK+ is not sufficient to link against libXRender, and leads to linker errors:

  CCLD     libwnck-3.la
  CCLD     wnckprop
  CCLD     wnck-urgency-monitor
  CCLD     test-pager
  CCLD     test-wnck
./.libs/libwnck-3.so: error: undefined reference to 'XRenderFindStandardFormat'
collect2: error: ld returned 1 exit status
Makefile:746: recipe for target 'wnck-urgency-monitor' failed
make[2]: *** [wnck-urgency-monitor] Error 1
make[2]: *** Waiting for unfinished jobs....

It is more correct to use the cairo-xlib-xrender pkg-config file to ensure linking to the correct libraries.
