Hi,
I try to build an image for a x86 architecture with RT-Preemtp Patch. So
I use the genericx86 machine and try to build the core-image-rt recipe.
This fails with the following errors:
/> ERROR: Nothing PROVIDES 'linux-yocto-rt' (but
/media/disk/myYocto/poky/meta/recipes-rt/images/core-image-rt.bb DEPENDS

genericx86 (not in COMPATIBLE_MACHINE)/
/> ERROR: Required build target 'core-image-rt' has no buildable providers./
/> Missing or unbuildable dependency chain was: ['core-image-rt',
'linux-yocto-rt']/
So I add the following parameter to my local.conf file:
/> COMPATIBLE_MACHINE_genericx86 = "genericx86"/
/> COMPATIBLE_MACHINE_quilt-native = "genericx86"/
/> PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-rt"/
But I get this error:
/> ERROR: Task 80
(/media/disk/myYocto/poky/meta/recipes-kernel/linux/linux-yocto-rt_3.14.bb,
do_compile) failed with exit code '1'/
In the log.do_compile file I see:

I already tried genericx86_64 machine and it’s still not working. Are
the genericx86 machine incompatible with the core-image-rt recipy? If
yes how can I build a x86 image with the RT patch?
What you did should have worked, since we do map the genericx86 BSP onto
one of the configurations that supports preempt-rt.
It looks like a compile error has crept in .. I'll start a build and see
if it is indeed broken at the moment (and then I can fix it).
Bruce
Many Thanks
