Mac M1 Ventura 13.4 cmake 3.26.4 numpy 1.24.3 linbomp 16.0.5 clang 14.0.3

@Curatum do you have any more information on this? I can build the library and run the examples on Mac M2 (Ventura 13.2.1) with Python 3.10.

@Curatum, do you have any more information as @felixdollack asked? If not, we will close this issue for administrative reasons.

Sorry. I had some turbulent weeks and completely overlooked the answer. I have no computer science background so maybe I am actually the problem. Is it sufficient to run pip install fcwt or do I have to manually build the library? I tried both and it did not work for me, but I will try again tomorrow. Sorry again for the late answer

Don't worry. Thanks for the quick response. Can you post the error message you get when installing fCWT via pip?

Curatum commented 1 year ago

I get no error message, even after uninstalling and installing it again. Still, the error persists while executing the code. I am now switching to a Windows machine, where it worked just fine. For me, that's the problem solved for now, but if you have any interest in finding the fault, I am happy to help and try some things.

Other than that, thank you for the amazing library. It is really a game changer :).

I have one more question: What kind of padding do you recommend for an aperiodic sensor signal? Because from what I read, no padding is included in the fcwt right?

I think you probably need to be building dual-arch binaries. Although the fact that pip installs happily would indicate it's happy with the architecture.

As an aside, it is possible to get a SIGILL when there's nothing wrong with the build. If I forget to return a value from a function and get a warning that I don't see, this is how clang often implements to undefined behaviour. Can make me scratch my head for a bit until I see the warning on my scrollback.
