Qemu-native requires alsa-libs-native

Qemu-native requires alsa-libs-native

[Koen Kooi]

Hi,

While attempting to build the qemuarm machine in oe-core I get this:

| + /OE/tentacle/build/tmp-angstrom_2010_x/work/x86_64-linux/qemu-native-0.13.0-r1/qemu-0.13.0/configure --prefix=/OE/tentacle/build/tmp-angstrom_2010_x/sysroots/x86_64-linux/usr --target-list=arm-linux-user,arm-softmmu,i386-linux-user,i386-softmmu,x86_64-linux-user,x86_64-softmmu,mips-linux-user,mips-softmmu,ppc-linux-user,ppc-softmmu,mipsel-linux-user --disable-werror --disable-vnc-tls --enable-kvm --audio-drv-list=oss,alsa --audio-card-list=ac97,es1370
| 
| Error: alsa check failed
| Make sure to have the alsa libs and headers installed.

But there's not alsa-libs-native in OE-core. Should we add such a recipe or disable also in qemu?

That's with:

OE Build Configuration:
BB_VERSION        = "1.13.0"
METADATA_BRANCH   = "master"
METADATA_REVISION = "f0afe5827570eff5442d2f9a9846b4098e5c3333"
TARGET_ARCH       = "arm"
TARGET_OS         = "linux-gnueabi"
MACHINE           = "qemuarm"
DISTRO            = "angstrom"
DISTRO_VERSION    = "v20110320-core"
TARGET_FPU        = "soft"


regards,

Koen

Koen,
We enabled alsa in configure for the feature of receiving sound from 
guest. It is assumed that audio system on host is already enabled.

I'm not sure if we need add alsa native, given that they are host 
specific. Besides alsa, we also need sound card driver on host, which is 
beyond the scope of our build system.
Maybe, we can check alsa lib first, and enabled "--audio-drv-list=alsa" 
after finding it. Or we can document alsa as build prerequisite?

I see following purposes of qemu-native:
(1) automated runtime images testing
(2) manual images testing/using

(1) should be used against small subset of compatible targets. For
oe-core this is set of qemu machines only. For automated testing
purposes qemu wav driver may be more suitable than alsa imho. As well
as vnc instead of sdl. This happens on build (testing?) host, which
may be node in large build farm. I would prefer to have minimal
dependencies on such nodes.

(2) is different. Here we need alsa and sdl. But this should happens
not on build host in ideal case. In common case user already have X11,
sdl, alsa, etc on his home workstation. So here we may use anything.

So, my idea to separate (1) and (2). we may use different recipes.
qemu-testing and qemu e.g. Then qemu-testing may have minimal set of
features suitable only for runtime testing but qemu may have full set
of features suitable for common usage.

If we need a dependency, it needs to either be listed in ASSUME_PROVIDED
or built. In this case we can general the needed alsa library easily so
I've merged Koen's patches.
