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

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.

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

This worked for me:

brew install notcurses

Then:

CFLAGS=-I/opt/homebrew/include pip install notcurses

However, this package seems broken. It is basically empty: https://github.com/dankamongmen/notcurses/issues/2803

[mttkay]

I think I'm running in circles here. This issue seems to be the reason it's empty, because the CI job does not build it anymore 💡 : https://github.com/dankamongmen/notcurses/issues/2803#issuecomment-2465703992

Publishing empty packages is sending people new to this library on wild goose chases. Maybe just take it down?
