Install pyaudio inside Toolbox fails

I created my first toolbox:
toolbox create groundstation and toolbox enter groundstation then installed pip via sudo dnf install pip3.

Then I ran this command to install some more stuff I need to run a python script:
pip3 install opencv-python Pillow matplotlib basemap pymavlink haversine pyaudio pyserial

But pyaudio fails to install:

  Building wheel for pyaudio (pyproject.toml) ... error

Googling shows people solved it by installing portaudio19-dev but I can’t install that:

sudo dnf install portaudio19-dev

How to install pyaudio via pip in a Toolbox?

It’s looking for gcc and it’s not installed in your toolbox. You might want to install basic compilation and build tools in your toolbox first:

sudo dnf install gcc

If you want to install all the tools you’ll likely need in one go:

sudo dnf group install development-tools

Added audio, python, toolbx

Apparently, pip3 install pyaudio won’t work. Instead, following the official documentation of pyaudio, by default it should not be installed via pip3. This worked:

sudo dnf install python3-pyaudio

Thanks for your quick support btw, much appreciated! Got it all working now.

edit: I now learned the hard way, you should install any dependencies for your python apps via dnf, not pip, unless its not available via pip3. Otherwise it won’t run. Weird errors. Mostly to do with opencv.

I removed the container (podman ps to list it and podman remove …` to remove it) and created a new toolbox container, then installed the dependencies I needed via dnf:

sudo dnf install python3-pyaudio python3-tkinter python3-pillow python3-matplotlib python3-basemap python3-opencv

It will install a shitload more than via pip3, but at least my program runs now.
