[Łukasz Kalamłacki]

Hey,


Do you have an issue compiling 6.1.2 linux kernel?

I cannot compile it.

For me it compiles and boots. You'll need to share your config and error
report if you want to get some help.

I was trying to compile on Debian Bullseye where default gcc is version
10, when I upgraded gcc to version 12 from sid repo i Was able to
compile too. On stable Debian without addition during compile
"segmentation fault" occurs at the compilation of cx8-i2c.c file. You
can try on kvm or virtualbox this compilation.

Sounds like a gcc bug you should be notifying the gcc developers about.

good luck!

To be precise I have this on gcc 10 in Debian:


during GIMPLE pass: fre
drivers/media/pci/cx18/cx18-i2c.c: In function ‘init_cx18_i2c’:
drivers/media/pci/cx18/cx18-i2c.c:300:1: internal compiler error:
Segmentation fault

As Greg said it's definitely a compiler bug, so it will interest Gcc
developers, or your distro's gcc package maintainers in case it's not
up to date. There are toolchains available on kernel.org here:

   https://mirrors.edge.kernel.org/pub/tools/crosstool/

The laest 10.x available is 10.4. If it works with this one it may indicate
that your package is lacking some recent fixes, so it might be a question
for your distro's gcc package maintainers. If it fails it indicates a bug
not yet fixed in gcc and your distro maintainers won't be of any help here,
you'll have to report it to the gcc devs instead.

Note that they'll very likely ask about a reproducer (and most likely your
config). But a quick test for me with this driver built as a module on
x86_64 with gcc-10.4 from kernel.org doesn't show any problem:

  $ make CROSS_COMPILE=/f/tc/nolibc/gcc-10.4.0-nolibc/x86_64-linux/bin/x86_64-linux- drivers/media/pci/cx18/cx18-i2c.o
  (...)
    CC [M]  drivers/media/pci/cx18/cx18-i2c.o
  $ ll drivers/media/pci/cx18/cx18-i2c.o

Hoping this helps,
Willy

Allright, my kernel config is available here:
https://kalamlacki.eu/KERNELS/kconfig-6.1

Compilation on 11th gen i5 core cpu using command:

make -j 9 bindeb-pkg

As we have both stated, we are not the people to be discussing this
with as the kernel source is not the problem at all, so there's nothing
we can do here, sorry.

I am aware Greg that this is not kernel release issue and rather gcc but
it occurs during kernel compilation and many people can have this issue
too and that is why I am discussing about it here.

Willy: Debian stable has gcc in version 10.2.1 as states my buildinfo
from compilation of kernel 6.1.1 as it can be checked here:
https://kalamlacki.eu/KERNELS/BUSTER/linux-upstream_6.1.1-1_amd64.buildinfo.


Best,

Łukasz

I had the same issue with you as I am using Debian 11 (bullseye) and followed Willy's suggestion to use the toolchains available on https://mirrors.edge.kernel.org/pub/tools/crosstool/, that solved my problem for compiling 6.0.16 version as well.

6.0.X kernel versions are already available via backports, so I think the fix to GCC version, that bullseye utilizes, will come to bullseye quite soon as the kernel package maintainers will see the issue when they will try to release 6.0.16 version to backports.

This issue was a strong reminder for me to switch back to the toolchains for compiling the kernel. I do acknowledge that it is quite convenient for users to just use the GCC that is available from the distribution but using the aforementioned toolchains ensures a smooth experience with compiling the kernel.

My 2 cents,
Pavlos

Hi Willy,

I can confirmed that no segfault reported when compiling
x86_64-defconfig + CONFIG_VIDEO_CX18 using default gcc from Debian 11,
so this can be hardware issues.

Thanks.

Unlikely, hardware issues rarely cause a crash on the same file in a
project as large as the kernel. However, a bug in the compiler may be
triggered by specific combinations of options, or even the environment
sometimes.

Also, Pavlos also got the problem on 6.0.16 and got it fixed by updating
the compiler.

I think that someone should report the bug to the debian gcc maintainers
and tell them that 10.4.0 as shipped on kernel.org fixes the problem. It
could help them reproduce the issue, update, confirm the problem is gone,
and issue a fixed package.

Thanks,
Willy
