Patchwork [2/2] qemu: Make qemu buildable inside qemux86/qemuppc target

From: Zhai Edwin <edwin.zhai@intel.com>

It requires libx11 and libGL(if enabled GL) for building, which introduce extra
dependence in qemuppc target. Futhermore, qemu's GL code is x86-oriented, thus
some hacks needed for building in qemupcc. For simplicity, just make qemu GL's
code for native only, so that qemu building is okay in world build.

[YOCTO #1011] got fixed.

The patch is fine but could we change this to something like:

# Only use the GL passthrough patches for native/nativesdk versions
$QEMUGLPATCHES = "\
    file://qemu-git-qemugl-host.patch \
    file://fix-nogl.patch \
    file://qemugl-allow-glxcontext-release.patch \
    file://init-info.patch \
    file://enable-i386-linux-user.patch \
    file://qemugl-fix.patch \
    file://opengl-sdl-fix.patch \
    "

SRC_URI_append_virtclass-native = "\
    ${QEMUGLPATCHES} \
    "

SRC_URI_append_virtclass-nativesdk = "\
    ${QEMUGLPATCHES} \
    file://glflags.patch \
    "

which is just a little bit neater. Also, no need for the commented out
line.

Cheers,

Richard

RP,
Thanks for your comments. I have modified it. Pls. pull @ same branch:

git://git.pokylinux.org/poky-contrib gzhai/master2
http://git.pokylinux.org/cgit.cgi/poky-contrib/log/?h=gzhai/master2

BTW, I saw qemugl_git.bb is extended as "nativesdk", and was curious about it as 
qemugl is hacked libgl inside qemu guest, thus should not be related to "native" 
case. Any reason? Meet the dependency requirement?

Thanks,
Edwin

I've merged this, thanks.

We need the GL code in nativesdk since this ships as part of the SDK/ADT
toolchain and we want the GL pass through support there.

Cheers,

Richard
