Nope. There's a range of supported major branches. This has been the
case for at least 15 years. Typically, we've supported 2-4 old
branches building current due to the needs of the FreeBSD community
and that community making sure it works often enough that we don't
just shut the door to it entirely. Each individual developer only
needs to test the latest branch, but that's not the same as what's
supported. From time to time we bump the minimum system, but it isn't
in lock step with the major branches.

We support building world on 10.3 and newer for -current today. There
were compiler changes to fix bad code generation between 10.2 and
10.3, however, so the usual "any stable-10' is no longer the case. In
fact, it's still supported building from the tip of stable/9 for
current. However, the same compiler bug is not fixed in the last 9.x
release, so there the upgrade is needed.

Anything less than buildworld is defintely not supported when the host
system isn't completely up to date. Well, make kernel-toolchain is
sufficient for make buildkernel.

That is the safest way, indeed.  But it should not be totally impossible
to build recent versions of -current on 10.x.

Normally, buildworld takes care of the heavy lifting by building all the
needed tools first.  But if you build only parts of the tree, you might
encounter "interesting" situations. :)

As far as I can see, the toolchain target does not install headers and
libraries.  Can you try the kernel-toolchain target instead?

Probably not, because you will be using /usr/bin/cc, and the wmmintrin.h
header in the base system.

Isn't it all bets are off if going to -current from anything but most
recent -stable?
Recommended practice[citation needed] would be
10-stable->11-stable->12-current.

What are you building, and how?  Did you do a buildworld before buildkernel?

-Dimitry



I did:

make toolchain -jXX

And then:

make buildkernel -jXX

And the error popped out. I'm not observing this error when building a 
12-current kernel from an 11-stable install.

Build failure 'wmmintrin.h' file not found

[Hans Petter Selasky]

Hi,

I'm seeing the following build-error trying to build 12-current from 
10-stable:


xxx/freebsd/sys/crypto/aesni/aesni_ghash.c:75:10: fatal error: 
'wmmintrin.h' file not found

#include 

Missing header exists:

xxx/freebsd/contrib/llvm/tools/clang/lib/Headers/wmmintrin.h

Missing include directory or compiler magic?
