cairo: upgrade from 1.8.10 to 1.10.0 none

Description Ke Yu 2010-11-16 19:33:16 UTC 
When I upgrade cairo from 1.8.10 to 1.10.0, and doing poky-image-sato do_rootfs,  the zypper will report:

"

cairo 1.10.0 should actually meet the requirement of >=1.8.10, so looks zypper does not correctly compare the version.

if i rebuild those recipes, i.e. increase the PR of the recipes (screenshot, lttng-viewer...) , and build again, the error disappear. the rpm spec becomes:  
Requires: cairo >= 1.10.0

Reproduce step:
1. build poky-image-sato from scratch with poky 4.0
# git checkout laverne-4.0
# . poky-init-build-env
# bitbake poky-image-sato

2. apply the attached patch to upgrade cairo, and build poky-image-sato again
# patch -p1 < cairo.patch
# bitbake poky-image-sato

3. the error will show out.

cairo: upgrade from 1.8.10 to 1.10.0

add patch of upgrade cairo
Comment 2 Ke Yu 2010-12-08 22:43:28 UTC 
it is not caused by rpm, instead, it is due to cairo renaming from libcairo2 to cairo2 during the upgrade. so mark this bug as invalid.
