@Xeno Thanks, that worked! Here's my detailed description of how to set up opentrack in the current version of Ubuntu, which is Ubuntu 22.04LTS #install needed packages time sudo apt install -y git cmake git qttools5-dev qtbase5-private-dev libprocps-dev libopencv-dev g++ subversion wine-development vim okular flightgear libeigen3-dev gcc-multilib g++-multilib wine32-development wine32-development-preloader wine32-development-tools cmake-curses-gui plocate #build opentrack from source mkdir delanclip # opentrack URL: https://github.com/opentrack/opentrack/releases/tag/opentrack-2022.1.1 cp opentrack-opentrack-2022.1.1.zip delanclip unzip opentrack-opentrack-2022.1.1.zip cd delanclip/opentrack-opentrack-2022.1.1 mkdir build cd build cmake .. # run the text menu configuration program ccmake # set the eigen3 path to /usr/include/eigen3 # set windows sdk to ON # choose continue # choose generate ccmake . # now compile and build make make install cd install/bin ./opentrack # in the opentrack gui, click the tool icon in the input section, then choose # Camera/Camera Settngs/Device to be your PS3 webcam, not an internal webcam # chose "Wine" under Output # then select the tool icon to the right and enter the path to the sims' # wine prefix # select "Start" and verify that the webcam is tracking the LED's # and that raw tracker data and game data numbers change as the # LED fixture is moved around. # copy the delanclip profile to the opentrack config directory cp ~/delanclip/DELANCLiP-Opentrack-Basic.ini ~/.config/opentrack-2.3 #if you use # sudo ./opentrack # to avoid setting permissions # the config directory will be /root/.config/opentrack-2.3 # if running delanclip with a sim that uses wine, call wine as follows # WINEESYNC=1 wine
