Hello,
Some news on this one: I discovered that the evaluation failure of the "guix" specification is correlated with the selected systems. When disabling "aarch64-linux" and "powerpc64le-linux", the evaluation succeeded. Now, when running: --8<---------------cut here---------------start------------->8--- mathieu@berlin ~$ guix pull -s powerpc64le-linux -v3 Updating channel 'guix' from Git repository at 'https://git.savannah.gnu.org/git/guix.git'... Building from this channel: guix https://git.savannah.gnu.org/git/guix.git 0598b5d building /gnu/store/m7ppw9lb65g99dajwkb56w05zqmydsdh-guile-bootstrap-2.0.drv... @ unsupported-platform /gnu/store/m7ppw9lb65g99dajwkb56w05zqmydsdh-guile-bootstrap-2.0.drv powerpc64le-linux while setting up the build environment: a `powerpc64le-linux' is required to build `/gnu/store/m7ppw9lb65g99dajwkb56w05zqmydsdh-guile-bootstrap-2.0.drv', but I am a `x86_64-linux' builder for `/gnu/store/m7ppw9lb65g99dajwkb56w05zqmydsdh-guile-bootstrap-2.0.drv' failed with exit code 1 build of /gnu/store/m7ppw9lb65g99dajwkb56w05zqmydsdh-guile-bootstrap-2.0.drv failed View build log at '/var/log/guix/drvs/m7/ppw9lb65g99dajwkb56w05zqmydsdh-guile-bootstrap-2.0.drv.gz'. --8<---------------cut here---------------end--------------->8--- It fails in the same way with aarch64-linux. That's because there's no offload or binfmt mechanism on berlin at the moment. I restored the /etc/guix/machines.scm to enable offloading, and suddenly "aarch64-linux" system is working again for the "guix" specification. "powerpc64le-linux" is still failing as we do not have a machine for that architecture currently available: p9.tobias.gr is commented out. Tobias, I'm not sure to remember why? Now there are multiple unclear points to me: 1. Why do we need an available machine with the foreign architecture to compute the corresponding "guix" derivation? Note that the evaluation of package derivations for foreign systems works even though a corresponding machine is not available: --8<---------------cut here---------------start------------->8--- mathieu@berlin ~$ guix build -s powerpc64le-linux -d hello /gnu/store/spzmh79qi21k26p15w27r3jjg95szg17-hello-2.12.1.drv --8<---------------cut here---------------end--------------->8--- 2. Why the following traces are not reported back by the inferior in charge of the evaluation of the "guix" derivation? --8<---------------cut here---------------start------------->8--- @ unsupported-platform /gnu/store/m7ppw9lb65g99dajwkb56w05zqmydsdh-guile-bootstrap-2.0.drv powerpc64le-linux while setting up the build environment: a `powerpc64le-linux' is required to build `/gnu/store/m7ppw9lb65g99dajwkb56w05zqmydsdh-guile-bootstrap-2.0.drv', but I am a `x86_64-linux' builder for `/gnu/store/m7ppw9lb65g99dajwkb56w05zqmydsdh-guile-bootstrap-2.0.drv' failed with exit code 1 build of /gnu/store/m7ppw9lb65g99dajwkb56w05zqmydsdh-guile-bootstrap-2.0.drv failed --8<---------------cut here---------------end--------------->8--- 3. Why does the "cuirass evaluate" process crashes when an inferior crashes (see the backtrace in my previous email)? I'll try to come-up with simple reproducers for those different points. In the meantime, the "guix" specification is working again for x86_64-linux, i686-linux and aarch64-linux systems which is a good news. Thanks, Mathieu
