Kernel compile error 11.2 -> 11.3 upgrade

Hello,

I get the error below compiling the GENERIC kernel from both 11.3-RelEng and 11-Stable:

Here is what I can find for CPU info from dmesg:

Code:

From what I can tell, the CPU is missing the AVX-512 instruction set. I can't find anything in the Errata regarding this error. Is the CPU just too old now?

TIA

That definitely not.
Figuring it out... if I remove my CPUTYPE from /etc/make.conf, I get this one:

So, how did You get that -march=native in there?
But, thats not really the problem....
Question is, how You try to do this kernel build? You often cannot just build a kernel from a newer release. You first have to build the compiler and tools from that release, and then use these to build the kernel. Otherwise, strange things may happen. There is some advice at the end of /usr/src/UPDATING, but I for my part, when switching releases, prefer to do the strict sequence: make buildworld, make buildkernel, make installkernel, go single-user, make installworld (add the appropriate parameters and mergemasters).

Okay. I tried and couldn't reproduce that error.
The current CPU should not matter, because that compiler should also be able to cross-compile. So it seems somehow your build-environment is hosed.
So I would start over with a consistent src-tree, doing make buildworld first, and then make buildkernel.
And, btw, this /usr/src/11.3/sys/amd64/compile/GENERIC doesn't look sane to me. The src tree is full of relative symlinks, it should be kept in one piece at the proper place. If You want separate trees for different versions to build, then I would suggest You do it this way - that's how it works for me:
  1. make a build directory, like /build/11.3
  2. install the currently running system into that place, e.g. make installworld DESTDIR=/build/11.3 (**) (or just copy the base installation to there).
  3. unpack the source tree into /build/11.3/usr/src
  4. chroot /build/11.3
  5. cd /usr/src; make buildworld; make buidlkernel KERNCONF=GENERIC
  6. then, when successful, for installation take /build/11.3/usr/src and /build/11.3/usr/obj and place them at /usr/src and /usr/obj of whereever the stuff shall be installed (jail, different system, ...). Then run the proper installation command.
(**) Addendum: I forgot something: At this point, after doing the make installworld, it is also necessary to do make distribution DESTDIR=/build/11.3 to properly populate /etc/ and friends in the chroot.

I've been working on this off and on as time permits, but I can't get past this error.

That error occurs while building world in the chroot'd (/build/11.3) /usr/src. Any suggestions?

Thanks for your help thus far.

Ups - big sorry! This is certainly my fault, I forgot a step. See addendum above.
 
I've made a bit more progress on this. For posterity's sake, devfs needs to be available in the chroot'd environment

e.g.
mount -t devfs devfs /build/11.3/dev/

I'm unable to get past this build error now. I've blown away the 11.3 source, and started with a fresh pull. Same result

What version is clang on your 11.2 system? See /usr/src/UPDATING for details.
Click to expand...

Code: 
~$ clang --version
FreeBSD clang version 6.0.0 (tags/RELEASE_600/final 326565) (based on LLVM 6.0.0)
Target: x86_64-unknown-freebsd11.2
Thread model: posix
InstalledDir: /usr/bin

I've been through UPDATING. Should I be using WITHOUT_CLANG and WITH_GCC to get 11.3 off the ground?
 
Nope, your clang seems new enough. You could try the advice in entry 20141231 about building and installing libc++ first, perhaps it helps. Not sure, your system setup seems strange somehow. Do you have enough free disk space to build everything?
