Failure to install using pip on mac

[KristofferC]

I wanted to try out some of the Python examples but on a mac but upon trying to install via pip I get:

  build/temp.macosx-11-x86_64-3.9/_notcurses.c:570:14: fatal error: 'notcurses/direct.h' file not found
      #include <notcurses/direct.h>

Full error

$ pip3 install notcurses

  ERROR: Failed building wheel for notcurses

I guess there is an -I that is missing to the temp directory where the project is built? I don't know shit about fuck when it comes to Python packaging though.

https://github.com/dankamongmen/notcurses/issues/2391 seems related.

As a follow-up question, what is the intended way to use the wrappers in the python folder? It seems with pip you get the ones in cffi but those seem quite a bit more spartan than the ones in python.

[dankamongmen]

yes, i have not yet switched to @igo95862 's wrappers (the ones in python/) for pip.

#1154 covers this. iirc, we were missing man pages or example binaries, something like that. we'd like to switch to them sooner rather than later.

[dankamongmen]

i'm now seeing general failure building either old or new python on our macOS ci. happy friday to me!

[dankamongmen]

@alexhsamuel , any chance you could look into this? =]

[alexhsamuel]

Sure. But... I just factory-reset my MacBook last night and installed Monterey. Will probably take me a couple days to get everything installed again.

Are there any updates on this? I am still encountering the same problem today
