package

[YOCTO #4973]
It fails to start qemu with core-image-sato on Fedora 19. The error
message shows:
Could not initialize SDL(No available video device) - exiting
Add dependecy libxext-native to qemu-native to fix this error.

This is one of the ugly dependencies we've tried to ignore.
We basically assume if your build machine has graphics, you have the
devel headers/libs there and qemu will autodetect and include graphics
support. Equally, if your build machine doesn't, it just won't build
graphics support. In general most people seem happy with this even if
its imperfect.
But, but... I do have libxext and libxext-devel installed... (and minimal works
just fine as the bug says)
libXext-1.3.2-1.fc19.x86_64
libXext-devel-1.3.2-1.fc19.x86_64
Also strace shows:
open("/lib64/libXext.so.6", O_RDONLY|O_CLOEXEC) = 11
read(11, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0`7`U1\0\0\0"..., 832) =
832
fstat(11, {st_mode=S_IFREG|0755, st_size=77376, ...}) = 0
mmap(NULL, 2169112, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 11, 0) =
0x7f0a493ee000
mprotect(0x7f0a493ff000, 2093056, PROT_NONE) = 0
mmap(0x7f0a495fe000, 8192, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 11, 0x10000) = 0x7f0a495fe000
close(11) = 0
It is a little weird, and it seems we need more work. :)

The F18 system which doesn't have a problem with sato has:
libXext-1.3.1-3.20130524gitdfe6e1f3b.fc18.x86_64
libXext-devel-1.3.1-3.20130524gitdfe6e1f3b.fc18.x86_64
Cheers,
Stefan
Adding libxext-native upsets this balance a little...
Cheers,
Richard
