I received this error while building opencv: make[2]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/build.make:128: modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_ffmpeg.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:8811: modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2 make: *** [Makefile:163: all] Error 2 It was after entering “make -j4” in the command line. There were a few red marked words before the code up here. Let me know if you would like to take a look.

@BigMan said in Create another config.js file: even easier! put all your configs into the config folder then just set which on to use #!/bin/bash # set my config export MM_CONFIG_FILE=~/MagicMirror/config/config1.js # then call mm.sh exec ~/MagicMirror/installers/mm.sh thanks @strawberry-3-141
