guix pull fails on arm64 due to cmake DEB self-tests

Hi!

I'm running the following commands on a arm64 GitLab shared runner node:

export LC_ALL=C.UTF-8

apt-get update

apt-get install -y guix podman ca-certificates

(guix-daemon --disable-chroot --build-users-group=_guixbuild &

guix pull --url=https://gitlab.com/debdistutils/guix/mirror.git\

|| (ls -la /var/log/guix/drvs/*/*.drv.gz; zcat /var/log/guix/drvs/qz/9fsb0935lpyssgg9428w9rvsypbfgv-cmake-bootstrap-3.24.2.drv.gz)

I get a build failure regarding "cmake-bootstrap" shown here:

I cannot reproduce this on my own arm64 machine running Trisquel.

It seems only cmake's DEB related self-tests fail:

Errors while running CTest

That make me believe that the minimal nature of the container has some

impact. Maybe some missing environment variable or tool or something?

That is usually present during normal builds but not this build.

The first failure starts here:

with output cited below. I don't spot any obvious problem. I suspect

something odd is happening when running 'dpkg'.

Any ideas how to debug this further?

Hi,

Simon Josefsson <simon@josefsson.org> skribis:

Looks like the problem is gone with a current-ish commit since

substitutes are available from both build farms:

Could you confirm?

Maybe the substitutes are now gone, because I just tried again and the

error looks the same:

If it got the binary substitutes, I suppose things would be fine.

Looking more carefully at the errors, I notice this part:

actual-err> cpack-cfg> set(DPKG_EXECUTABLE "/usr/bin/dpkg")

actual-err> cpack-cfg> set(READELF_EXECUTABLE "/gnu/store/pqai4n95zn5wdw430gslb00sb967jdg8-binutils-2.41/bin/readelf")

So for some reason building cmake-bootstrap in guix in Debian picks up

Debian's /usr/bin/dpkg, doesn't it?!

I suppose that Guix's build servers aren't running Debian, so it won't

find any /usr/bin/dpkg.

Maybe this has something to do with why it is only all the DEB-related

cmake self-tests that fails here.

(However it doesn't explain why I couldn't reproduce the same problem on

my own arm64 machine that is running Trisquel. Maybe substitutes just

happened to be available when I tried it?)

The GitLab run above is in a minimal debian 12 container, and the

commands are essentially these:

- apt-get update

- apt-get install -y buildah ca-certificates eatmydata

- time eatmydata buildah build -t ...

With the Containerfile running essentially this:

set -x && \

cat /etc/os-release && \

locale -a && \

apt-get update && \

apt-get install -y guix netbase && \

(env LC_ALL=C.UTF-8 guix-daemon --disable-chroot --build-users-group=_guixbuild --discover=no &) && \

set && \

(guix pull --url=https://gitlab.com/debdistutils/guix/mirror.git\

It would be really surprising if '/usr/bin/dpkg' could be found or

accessed from within the package build environment, unless the build

isolation has been disabled.

Are you able to confirm if that is what's happening?
