[PATCH 2/2] local.conf.sample: qemu-native DEPENDS libxext-naive

[Robert Yang]

Fixed do_configure error:

ERROR: User requested feature sdl
       configure was not able to find it.
       Install SDL devel

This is error from log.do_configure, and if we check config.log, the error is:

sysroots/x86_64-linux/usr/lib/libXext.so.6: undefined reference to `_XEatDataWords'

The _XEatDataWords is provided by libX11.so, the dependencies are:

qemu-native -> sdl(from the host) -> libXext.so(maybe host or native) -> libX11.so (maybe host or native)

We may meet the error if host's libX11.so doesn't provide _XEatDataWords, and native's
libX11.so has been removed (for example, rebuild).

Another way to fix is: let qemu-native depend on libxext-naive when sdl is
enabled, for example:

PACKAGECONFIG[sdl] = "--enable-sdl,--disable-sdl,libsdl libxext-native,"

But this might be incorrect since target sdl or qemu may not require X11, so
set:

DEPENDS_pn-qemu-native += "libxext-naive"

in local.conf.sample to fix problem.

Doesn't this belong in qemu-native's PACKAGECONFIG definition for sdl?

Yes, but I don't know how to do it, what I know is:

PACKAGECONFIG[sdl] = "--enable-sdl,--disable-sdl,libsdl libxext,"

That would affect the target qemu, too, for example, when the user defines:

PACKAGECONFIG = "sdl" for target qemu, then the depends would be:

"libsdl libxext"

But the target sdl or qemu may not require X11.

Do you know how to define it for qemu-native only, please ?

Surely something like this would work:

PACKAGECONFIG[sdl] = "--enable-sdl,--disable-sdl,libsdl ${NATIVEDEPS},"
NATIVEDEPS = ""
NATIVEDEPS_class-native = "libxext-native"

Context: that function was added to libX11 1.6, and numerous other
client libraries started using it to avoid security problems.  Older
hosts won't have it, but they also won't have libraries that are using
it.  So as far as I can tell the only way of replicating this is to
have a sysroot which contains libxext but not libx11.  Considering
libxext depends on libx11 that's not very likely.

What's your actual replication method?

We have also seen this on Yocto's AB.

On Ubuntu 12.04 x86_64:

The link route is:

qemu-native's do_configure sdl checking:
/usr/lib/x86_64-linux-gnu/libSDL.so --> 
<sysroots>/x86_64-linux/usr/lib/libXext.so.6 --> /usr/lib/x86_64-linux-gnu/libX11.so

So it is:
host sdl -> sysroot libXext.so.6 -> host X11.so

qemu-native doesn't depend on libxext-native, so the error would happen
if the libx11-native is being rebuilding and the host's libX11.so doesn't
have _XEatDataWords.

Manually reproduce on Ubuntu 12.04 x86_64:

$ bitbake qemu-native libx11-native libxext-native
$ bitbake qemu-native libx11-native -ccleansstate && bitbake qemu-native

Then errors:

| ERROR: User requested feature sdl
|        configure was not able to find it.
|        Install SDL devel

This is where I insert my moan that the sysroot needs to have locking
and not modified during builds...

Maybe qemu-native should have a wrapper script that removes the
sysroot from LD_LIBRARY_PATH?  It's a native binary that doesn't need
anything in the sysroot, so let's stop it even looking there.

I'm afraid that the lock can't fix such an issue when build them manually.

I'm afraid not, the qemu-native does depend on a few native recipes:

DEPENDS_class-native = "zlib-native alsa-lib-native glib-2.0-native 
pixman-native dtc-native"
