-These steps are what I use to compile stuff by copying things from my Windows computer. ​ A normal ​user would probably just grab the svn tree.+Here is how to setup the Raspberry Pi to support ​normal ​OpenGL or GLES (both with acceleration) and be able to compile ​the Proton SDK examples  (tested with Raspbian "​Jessie"​ on 6/18/2016)
  
-Steps:+From my tests I got it working two ways: 
 + 
 +1.  Set it up using the OpenGL experimental driver. ​ Result: Proton examples only work in X11 in windows mode.  Fullscreen (using the SDL2 harness) didn't work.  [[proton:​raspi_opengl_setup|Directions to setup]] 
 + 
 +2.  Set it up using GL ES, won't work in X11, works full screen by starting from console. ​ This is more useful for me as it's more pedal to the metal and easier to get 60 fps, no x overhead. ​ With this method we're setting up our own EGL context manually, but still using the SDL2 harness for other things

 +** Instructions to setup GLES with Raspberry Pi and run Proton SDK examples ** 
 + 
 + 
 +These steps are what I use to compile stuff by copying things from my Windows computer. ​ A normal user would probably just grab the svn tree and run .sh files. 
 + 
 +  * Give the video card more memory on the pi.  Run raspi-config and give it at least 128 or so to be safe. 
 +  * Install cmake on the pi (sudo apt-get install cmake) 
 +  * Do "sudo rpi-update"​ to make sure your firmware is updated 
 +  * Run the following from a shell: 
 + 
 +<​code>​ 
 +sudo apt-get -y install xcompmgr libgl1-mesa-dri && sudo apt-get -y install libalut0 libalut-dev && sudo apt-get -y install mesa-utils 
 + 
 +sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev libgles2-mesa-dev libgegl-dev 
 +</​code>​ 
 + 
 +  * Do the following from a shell window to install SDL2 from source: 
 + 
 +<​code>​ 
 +cd ~  
 +wget https://​www.libsdl.org/​release/​SDL2-2.0.4.tar.gz  
 +tar zxvf SDL2-2.0.4.tar.gz  
 +cd SDL2-2.0.4 && mkdir build && cd build  
 +../​configure --host=armv7l-raspberry-linux-gnueabihf --disable-pulseaudio --disable-esd --disable-video-mir --disable-video-wayland --disable-video-x11 --disable-video-opengl 
 +make -j 5  
 +sudo make install  
 +</​code>​

 +Step 2: Proton stuff
  
   * Install linux tools for Windows, rsync and ssh should work from the command line   * Install linux tools for Windows, rsync and ssh should work from the command line
   * Setup a ssh key pair so you don't have to type passwords   * Setup a ssh key pair so you don't have to type passwords
   * Edit SetupVars.bat and edit the IP to the pi   * Edit SetupVars.bat and edit the IP to the pi
-  * Give the video card more memory on the pi.  Run raspi-config and give it 128 or 256 (good for the pi3) 
-  * Install cmake on the pi (sudo apt-get install cmake) 
-  * Install SDL2 on the pi (sudo apt-get install libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev libsdl2-mixer-dev) 
   * Run CopyStuffToPi.bat. ​ There should now be a ~/proton tree on the pi   * Run CopyStuffToPi.bat. ​ There should now be a ~/proton tree on the pi
 +  * Edit the RTBareBones/​linux/​CMakeLists.txt file and make sure OPTION(RASPBERRYPI_GLES11 OPTION(RASPBERRYPI_GLES11 "​Compile for Raspberry PI GLES" ON) is uncommented and OPTION(RASPBERRYPI_OPENGL "​Compile for Rasperry PI OpenGL"​ ON) is commented out. 
   * RTBareBones/​CopyStuffToPiAndCompileLoop.bat and it should update that example and compile it in a loop   * RTBareBones/​CopyStuffToPiAndCompileLoop.bat and it should update that example and compile it in a loop
  
 +The last step of the build copies the rtbarebones binary to /​RTBareBones/​bin (as that's where the media is), so go to that dir and run "​./​rtbarebones"​ and it should work.
 +
 +RTSimpleApp is much the same, although you'll need SDL2's mixer as well.  Unlike with the base SDL2, we can just grab a pre-compiled one like this:
 +<​code>​
 +sudo apt-get libsdl2-mixer-dev
 +</​code>​
 +And that should compile ok. It should run 60+ fps at 720p on a Raspi 3.
  
-If you look at the RTBarebones/​linux dir you'll see the CMakeLists.txt file autodetect the pi and sets up GLES 1.1 headers stuff for it.
