Blink Example Fails #285
Comments

Thanks for pointing this out.
Has been some reorganization lately, hoping it's something simple but will
see if it's something funny related to python versions 🤞

I'm assuming this project uses Python3.9, as it relies on distutils,
however I don't think the documentation mentions this anywhere. I had to
alias my python3 command.
Running pipelinec --help works as expected and exits without error.
Perhaps I'm doing something wrong/my environment is wrong.

Ah OK - I missed the part about this being on Mac. I am not able to recreate this on my Linux system. PipelineC has only ever been tested on Linux, so I am just starting to speculate about what could be going on for you. (and any python3 version should work fine out of the box, why not specified specific version for non-developers). Seems like something is wrong dealing with include statements during preprocessing. Is At one point there was an issue of some I am going to make a general issue for 'pipelinec doesnt work on mac' and tag you in it, continue investigating there. In the short term using PipelineC on a Linux machine, virtual even, is the recommended fix. |

If you don't want to jump over to a Linux system to continue, lets discuss further if we can make things work over on Mac #286 👍 |

Right, I just tested it again in a Ubuntu 20.04 VM (via UTM, virtualized so still arm-based) and the This is likely an issue with Apple's |
