Python3-native illegal instruction on poky dunfell

Hello community, I am trying to build core-image-minimal using poky only, on the dunfell branch. On certain machines the build fails unexpectedly with the following error: Build Configuration: BB_VERSION = "1.46.0" BUILD_SYS = "x86_64-linux" NATIVELSBSTRING = "universal" TARGET_SYS = "x86_64-poky-linux" MACHINE = "qemux86-64" DISTRO = "poky" DISTRO_VERSION = "3.1.4" TUNE_FEATURES = "m64 core2" TARGET_FPU = "" meta meta-poky meta-yocto-bsp = "dunfell:cd3abf42dae2310ecaa8a97b2c08378a9f6e1282" Initialising tasks: 100% |####################################################################################################################################################################| Time: 0:00:11 Sstate summary: Wanted 1025 Found 0 Missed 1025 Current 126 (0% match, 10% complete) NOTE: Executing Tasks ERROR: python3-setuptools-native-45.2.0-r0 do_compile: 'python3 setup.py build ' execution failed.

The configuration of this machine is: Distributor ID: Ubuntu Description: Ubuntu 18.04.5 LTS Release: 18.04 Codename: bionic Linux vm 5.4.0-54-generic #60~18.04.1-Ubuntu SMP Fri Nov 6 17:25:16 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux 4 x Intel(R) Core(TM) i5-8350U CPU @ 1.70GHz The python3-native binary generated by Yocto works and I can run it on the host. I have identified that setup.py file of python3-setuptools-native recipe, part of do_compile fails with illegal instruction when trying to import setuptools. On other machines the build has no issues. The machine with issues is under a VPN and a proxy (company's machine). Do you have any hint as why this might happen? Thank you and looking forward to your feedback, Daniela-Mărinela Bistrean

Are you sharing sstate between multiple builders?

Thank you very much for your response! I have only one builder and the sstate is not shared. Additionally I also tried building on the zeus branch and the build fails with the same error (illegal instruction) but this time at do_configure task. And do_configure calls the same python3-native with setup.py but with a different parameter. Any help or hint is appreciated.

Hello again, I solved the mystery and I am describing it here in case anyone has the same problem. Basically, what I omitted last time and seems to be critical to the problem is that I was running a virtual machine. The one bit causing the issue was that avx2 was disabled in my VM and python requires it. Enabling avx2 fixed the issue. I managed to reproduce the issue with qemu using the following command line: $ qemu-system-x86_64 -enable-kvm -boot d -m 8G -cpu host,-avx2 -smp 4 -hda disk.bin Daniela-Marinela Bistrean
