Probably the same as issue 105 on GitHub: GCC does not seem to provide the needed output on that platform. Maybe adding support for -mcpu would fix it, that would be GitHub issue 78.
Any chance you could try pull request https://github.com/hartwork/resolve-march-native/pull/107 ? The description there includes commands to easy running code off the branch. Thanks in advance!

Roy, I have pushed fixes two times more since you tried. Could you try again with the latest commit (3c50184e022a2d8c4b02b8904c9742b9220e4959)? I'm optimistic that you'll get better results this time.

Hello Roy, I can tell from part of the traceback that it's not running the latest code from commit 3c50184e022a2d8c4b02b8904c9742b9220e4959 — runner.py line 44 would be different. Are you on the right branch? Did you update the remote and hard-reset the branch to the latest changes? How did you install the code from Git to /usr?
I used the script in https://github.com/hartwork/resolve-march-native/pull/107 and checked git log to see that HEAD was at commit 3c50184e022a2d8c4b02b8904c9742b9220e4959 I'll try again Wed evening UK time.

If the package in question is not packaged for Gentoo, please consider installing it inside a virtual environment, e.g.: python -m venv /path/to/venv . /path/to/venv/bin/activate pip install mypackage To exit the virtual environment, run: deactivate The virtual environment is not deleted, and can be re-entered by re-sourcing the activate file. note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. hint: See PEP 668 for the detailed specification.

Hello Roy, resolve-march-native run from inside a fully activated virtualenv should not show files from /usr/lib/python3.11/ in tracebacks but from inside the virturalenv — something does not seem to work during "hash" or "source venv/bin/activate", right? Does "type resolve-march-native" indicate anything helpful? Are you in Bash?

Does "type resolve-march-native" > indicate anything helpful? Are you in Bash? Sebastian, I'm a twit. The app-misc/resolve-march-native-2.2.0 was still installed, as # type resolve-march-native resolve-march-native is /usr/bin/resolve-march-native returned. That's now removed. Deactivating the virtual environments (one user one root), removing the /tmp files to clean up the mess, then starting over, now gets me ... (venv) roy@moriarty /tmp/tmp.9U4ujXZPjq/resolve-march-native $ hash resolve-march-native -bash: hash: resolve-march-native: not found. There is a ./resolve-march-native though. Then (venv) roy@moriarty /tmp/tmp.9U4ujXZPjq/resolve-march-native $ resolve-march-native --debug -bash: resolve-march-native: command not found as there is nothing called resolve-march-native to execute.
The "pip install -e ." run from inside the activated virtualenv is what produces the command, located at venv/bin/resolve-march-native (which is in $PATH).
I'll put the code with -mcpu= support as 3.0.0 into Gentoo now, all other arm64 boxes tried so far worked well with the new code. We can always improve and fix more after as needed. New ebuild coming up in a minute.

Thank you for your efforts here!
Sebastian, Thank you. My emag 81880 returns moriarty ~ # resolve-march-native -mcpu=emag+crc and a Pi 4 shows Pi_Router SSD ~ # resolve-march-native -mcpu=cortex-a72+crc
Glad to hear, thanks for the update!
