Installation on Raspberry Pi

[Andrew123098]

Hello,
So I spent the last few days trying to install this library on a Raspberry Pi Zero 2 W running Bookworm 12. Needless to say, it was very difficult because the pip install did not work (failed to find certain .hpp files) and compiling the code from source posed many obstacles due to the makefiles not properly pointing to certain libraries and not linking properly to certain dependencies. After many attempts, I was finally able to do it. Thank you for making this library. Hopefully my little guide below can help others who want to use it.

Installing Whycon Library on Pi Zero 2 W

Increase Swap Memory Size

sudo nano /etc/dphys-swapfile
CONF_SWAPSIZE=2048
Ctrl+s Ctrl+x
sudo systemctl stop dphys-swapfile
sudo systemctl start dphys-swapfile

Verify new swap size

free -h

Installation of module and submodule (submodule is protected for unknown reason)

git clone https://github.com/ivomarvan/pywhycon.git
cd pywhycon
rmdir whycon_core
git clone https://github.com/ivomarvan/whycon_core.git

Create virtual environment with dependencies

python3 -m venv env
pip install numpy pybind11 pkgconfig
pip install opencv-python

Install global dependencies

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential cmake git pkg-config libjpeg-dev libtiff-dev libpng-dev
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
sudo apt-get install libxvidcore-dev libx264-dev libgtk-3-dev
sudo apt-get install libatlas-base-dev gfortran python3-dev
sudo apt-get install build-essential cmake git
sudo apt-get install libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python3-dev python3-numpy libtbb2 libtbb-dev libdc1394-22-dev
sudo apt-get install libjpeg-dev libpng-dev libtiff-dev libopenexr-dev libatlas-base-dev gfortran
sudo apt-get install libhdf5-dev libhdf5-103
sudo apt-get install pybind11-dev
sudo apt-get install libopencv-dev

Edit the make files in both the pywhycon and whycon_core repositories:
I have attached these files to this post.
whycon_makefiles.zip

Make sure all files are owned by the user and not the root

sudo chown -R pi:pi /home/pi/pywhycon/

Compile modules (Compiling pywhycon takes +45minues, get a coffee)

cd whycon_core
make all -d
cd ..
make all -d

Install the modules into the local library

python3 setup.py install

Confirm everything works

python3 usecases/show_help.py

Dear @Andrew123098,
thank you for your hard work. Good job.

Sorry, but I no longer support this project.

Hello @ivomarvan ,
Understood. Is the library in a usable state assuming I could perform the installation correctly?
Thanks,
Andrew
