Comment 1 chnarius 2013-04-11 08:11:52 UTC 
Same issue on Centos 5.8.
Comment 2 Richard Purdie 2013-04-11 11:30:56 UTC 
This is wayland-native, right? Not wayland itself for the target?
Comment 3 Ross Burton 2013-04-11 13:55:26 UTC 
Presuming this is wayland-native we don't need to build all of it, just the scanner.  Changing the recipe to just build the scanner should speed the build and might fix the issue.
Comment 4 Ross Burton 2013-04-11 17:10:58 UTC 
I think I've got a fix:

http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/commit/?h=ross/wayland-native&id=350195f7c6ac5e3b9edc82f8e1f7fa0a8ba56346

Can you please test this, I don't have a centos machine to hand.
Comment 5 chnarius 2013-04-12 05:09:47 UTC 
That fixes the issue. Thanks.
Comment 6 Laurentiu Palcu 2013-04-12 06:49:49 UTC 
Fixed by Ross's commit. Closing.
Comment 7 Ross Burton 2013-04-12 07:41:02 UTC 
This hasn't landed in master yet, reopening.
