poky master issue with kernel and gcc version

[Eystein Måløy Stenberg]

Hi,

I am trying to build a vexpress-qemu machine targe from poky's master 
branch, but I get this error compiling the kernel:

| 
/home/yocto/poky/build/tmp/work-shared/vexpress-qemu/kernel-source/include/linux/compiler-gcc.h:121:30: 
fatal error: linux/compiler-gcc6.h: No such file or directory

Apparently it is picking gcc 6.1 and kernel 4.1.24, which do not play 
well together.

The best approach is probably to use kernel 4.2 or newer. Is there a bug 
filed for this? I would think this is affecting quite a lot of people as 
I am not doing any special configuration for my build.

Thank you.

We've already fixed all the gcc6.x builds for the supported machines
in linux-yocto 4.1/4.4.

What kernel tree is that building ? upstream ? linux-yocto ? And if
linux-yocto, what branch ?

It is building linux-yocto 4.1. I have attached the compilation log, in 
case that helps.

What I am doing is simply building a vexpress-qemu machine with poky's 
master, so it should be quite straightforward to reproduce.

In particular, I am following our projects guide for creating a Mender 
build at 
https://github.com/mendersoftware/meta-mender/blob/master/README.md, but 
I don't think it reaches the Mender-specific layers.

Thanks for the help and let me know if there's anything else you need.

I'm only validating the oe-core qemu* and yocto reference BSPs. My hands
are full with them at the moment.

So setting up to build with that config isn't something I can do at
the moment.

But I can assure you that qemuarm, and the beaglebone have both been
built and booted with gcc6.x, so the relevant patches are present.
