Compiling on the Raspberry Pi (Raspbian Jessie)

Steps to install Attract-Mode on Raspbian Jessie:

• Create a build environment

cd ~ mkdir develop ```````

• Install "sfml-pi" and Attract-Mode dependencies

sudo apt-get install cmake libflac-dev libogg-dev libvorbis-dev libopenal-dev libjpeg62-turbo-dev libfreetype6-dev libudev-dev libavutil-dev libavcodec-dev libavformat-dev libavfilter-dev libswscale-dev libavresample-dev libfontconfig1-dev ```````

• Download and build sfml-pi

cd ~/develop git clone --depth 1 https://github.com/mickelson/sfml-pi sfml-pi mkdir sfml-pi/build;cd sfml-pi/build cmake .. -DSFML_RPI=1 -DEGL_INCLUDE_DIR=/opt/vc/include -DEGL_LIBRARY=/opt/vc/lib/libEGL.so -DGLES_INCLUDE_DIR=/opt/vc/include -DGLES_LIBRARY=/opt/vc/lib/libGLESv1_CM.so sudo make install sudo ldconfig ```````

• Download and build Attract-Mode

cd ~/develop git clone --depth 1 https://github.com/mickelson/attract attract cd attract make USE_GLES=1 sudo make install ```````

If all those steps worked, then it should be ready to go!

Additional Notes

• Add the parameter "-j4" when you run make on a pi2 or pi3 to speed the build significantly
• If you get image display corruption, try adding framebuffer_depth=32 to the config file in the /boot folder.
• FFmpeg can be built with MMAL support to get hardware accelerated video decoding on the pi: https://ubuntu-mate.community/t/tutorial-build-or-download-ffmpeg-libavcodec-with-mmal-support-hardware-acceleration-video-decoding/3565

Notes for RetroPie

If you don't use the custom version of SFML noted above (sfml-pi), then Attract mode will need an X environment to run (which RetroPie does not ship with)

to get it to work you can do

sudo apt-get install xinit

then to start attract mode you type xinit attract in the terminal
