[Qemu-devel] [PATCH v2 0/2] fix building failure with pixman

[Hu Tao]

commit a93a3af9 introduces use of PIXMAN_TYPE_RGBA, but it's only available
in pixman >= 0.21.8. If pixman doesn't meet the version requirement, qemu
will fail to build with following message:

qemu/ui/qemu-pixman.c: In function ‘qemu_pixelformat_from_pixman’:
qemu/ui/qemu-pixman.c:42: error: ‘PIXMAN_TYPE_RGBA’ undeclared (first use in this function)
qemu/ui/qemu-pixman.c:42: error: (Each undeclared identifier is reported only once
qemu/ui/qemu-pixman.c:42: error: for each function it appears in.)

This series fixes this problem, also bumps pixman to pixman-0.32.6.

changes to v1:
  - bump pixman to pixman-0.32.6

Hu Tao (2):
  pixman: update internal copy to pixman-0.32.6
  configure: check for pixman-1 version

[Qemu-devel] [PATCH v2 1/2] pixman: update internal copy to pixman-0.32.6

[Hu Tao]

commit a93a3af9 introduces use of PIXMAN_TYPE_RGBA, but it's only available
in pixman >= 0.21.8. Although commit f27b2e1d bumped pixman to pixman-0.28.2,
but the change was reverted later by 7b1b5d19.

This patch updates internal copy of pixman to pixman-0.32.6 to fix the
problem.

Ah, so my memory wasn't totally wrong, the update got reverted
(apparently by mistake).  Thanks for the patches, I'll go prepare a pull
request.

qemu/ui/qemu-pixman.c:42: error: (Each undeclared identifier is reported only once

This patch fixes the problem by checking the pixman version.
