install failure on OSX Ventura

[steeley]

following your install instructions:
sudo python3 -m pip install pyo

from pyo import *

produces this error:
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/pyo/_pyo.cpython-311-darwin.so, 0x0002): Library not loaded: /usr/local/opt/flac/lib/libFLAC.12.dylib

[belangeo]

It should not try to load libFLAC from usr/local/opt... Is there a libFLAC.12.dylib right next to _pyo.cpython-311-darwin.so? Intel or ARM processor?

This is on MacBook intel i9 OSX Ventura.

[belangeo]

@steeley Ok, I think I know what the problem is... Next week, I should be able to build a new installer for you to try. I'll let you know when it's available.

[steeley]

fantastic - thanks for the help. I look forward to testing for you.

Did you manage to solve the error? I'm trying to download Python on Windows 11 on the same Python version 3.12.1 and when installing pip I get that error.

[steeley]

still waiting for a new version of PYO installer

[d4lion]

Sure, i use a lower python version and all is fine.

I noticed a similar issue with libportmidi, @belangeo. In the wheel building script, I think the wrong libportmidi version is used here. If you download the wheel from PyPi, unzip it, cd into the pyo directory and run otool -l _pyo.cpython-311-darwin.so, you'll see that it's attempting to load the libportmidi from /usr/local/opt/portmidi/lib/libportmidi.2.dylib. In the wheel file, it's actually libportmidi.2.0.3.dylib. So I think that script needs to be updated. Not sure if anything in the setup.py needs to change as well.

On an arm mac I was able to get this to work after getting the error about libflac by install ffmpeg with brew.
brew install ffmpeg
