Bug#1035933: linux-image-6.1.0-8-amd64-unsigned: fails to build (llvm-strip not found, missing dependency?)

[Claude Heiland-Allen]

Package: linux-image-6.1.0-8-amd64-unsigned
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)
X-Debbugs-Cc: cla...@mathr.co.uk

Dear Maintainer,

* What led up to the situation?

I wanted to patch the kernel source to see if it would help an issue I was having,
so I followed my usual steps when changing a Debian package locally:

sudo apt build-dep linux-image-6.1.0-8-amd64-unsigned
mkdir linux
cd linux
apt source linux-image-6.1.0-8-amd64-unsigned
cd linux-6.1.25
# make changes to the source code
# specfically some warning prints in devices/usb/host/xhci-ring.c
debuild -i -us -uc -b

* What was the outcome of this action?

The build failed after some time with:

...
llvm-strip -g /home/claude/linux/linux-6.1.25/debian/build/build-tools/tools/bpf/bpftool/profiler.bpf.o
make[4]: llvm-strip: No such file or directory
make[4]: *** [Makefile:187: /home/claude/linux/linux-6.1.25/debian/build/build-tools/tools/bpf/bpftool/profiler.bpf.o] Error 127
make[4]: *** Waiting for unfinished jobs....
llvm-strip -g /home/claude/linux/linux-6.1.25/debian/build/build-tools/tools/bpf/bpftool/pid_iter.bpf.o
make[4]: llvm-strip: No such file or directory
make[4]: *** [Makefile:187: /home/claude/linux/linux-6.1.25/debian/build/build-tools/tools/bpf/bpftool/pid_iter.bpf.o] Error 127
make[4]: Leaving directory '/home/claude/linux/linux-6.1.25/tools/bpf/bpftool'
make[3]: *** [/home/claude/linux/linux-6.1.25/debian/rules.d/tools/bpf/bpftool/Makefile:15: all] Error 2
make[3]: Leaving directory '/home/claude/linux/linux-6.1.25/debian/build/build-tools/tools/bpf/bpftool'
make[2]: *** [debian/rules.real:538: build_bpftool] Error 2
make[2]: Leaving directory '/home/claude/linux/linux-6.1.25'
make[1]: *** [debian/rules.gen:1494: build-arch_amd64_real_bpftool] Error 2
make[1]: Leaving directory '/home/claude/linux/linux-6.1.25'
make: *** [debian/rules:39: build-arch] Error 2
dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
debuild: fatal error at line 1182:
dpkg-buildpackage -us -uc -ui -i -b failed

* What outcome did you expect instead?

I expected apt to have fetched all the build-time dependencies of the package,
and the build to have succeeded.

* What exactly did you do (or not do) that was effective (or
ineffective)?

After

sudo apt install llvm

then

debuild -i -us -uc -b

worked as expected.


Thanks for your work on this package,


Claude

Thanks for the information. I don't see why it should use llvm, on the
other hand the kernel Makefile is rather clear when to use it. Can you
check if you an still reproduce the problem?

Control: severity -1 minor
Control: tags -1 + moreinfo

Hi Claude,

given your information and that the package builds fine on the buildds I
downgrade this to minor and add a moreinfo tag.

Cheers Jochen
