Hi,

• To run on Ubuntu 24.04, I followed these steps:
  1. Followed the print statement changes in camera.pyx outlined here: https://github.com/bensondaled/pseyepy/commit/ea7a6d3fcb71eb8d1a99d6c19b314f8d3fc00c5e
  2. Installed lastest libusb libray: $ sudo apt install libusb-1.0-0-dev
  3. Ran the installation script with pip: $ pip install -v .
  4. Installed some other packages: pip install pillow h5py
  5. I moved the shared object file (e.g., cameras.cpython-310-x86_64-linux-gnu.so) which was under one of the build dirs (e.g., ./build/lib.linux-x86_64-cpython-310/pseyepy) to ./pseyepy/cameras.so.
  6. I added this directory to my $LD_LIBRARY_PATH variable: $ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/...{INSERT-YOUR-PATH}.../pseyepy/pseyepy.
     • Alternatively, you can add this export command to the last line of your ~/.bashrc file for variable permanance.
  7. I had some trouble with USB permissions, so I made the following changesa: a. Create a udev rule file: $ sudo nano /etc/udev/rules.d/99-usb.rules b. Add the following text: SUBSYSTEM=="usb", MODE="0666", GROUP="plugdev" c. Add your user to the "plugdev" group: $ sudo usermod -aG plugdev $USER d. Reload: $ sudo udevadm control --reload-rules e. Trigger: $ sudo udevadm trigger d. Verify that your permissions where updated: $ ls -l /dev/usb/001/010

Hope this helps!
