-** Experimental ​and for linux pros only **+** Compiling Proton ​and its examples on the Raspberry Pi with GL ES **
-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)+As a base, I started with RetroPi (the image from 7/28/2018) on a Raspberry ​3 B.  I should try it with a vanilla Raspbian Stretch install ​and see if that works too.
-From my tests I got it working two ways:+First install Proton and compile its RTPack utility:
-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]]+I ssh'​ed ​in and did:
-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+<code bash> 
 +cd ~ 
 +git clone https://​​SethRobinson/​proton.git 
 +Now let's build Proton'​s RTPack utility, will come in handle later.
-** Instructions to setup GLES with Raspberry Pi and run Proton SDK examples ** +<​code ​bash
- +cd ~/​proton/​RTPack/​linux 
- +sh
-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>​ </​code>​
-  * Do the following from a shell window to install SDL2 from source:+Now let's compile and run RTBareBones:
-<​code>​ +<​code ​bash
-cd ~  +cd ~/proton/RTBareBones/linux 
-wget​SDL2-2.0.4.tar.gz ​ +sh 
-tar zxvf SDL2-2.0.4.tar.gz ​ +cd ../bin 
-cd SDL2-2.0.4 && mkdir build && cd build  +./RTBareBones
-../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>​ </​code>​
 +If that worked, enjoy the spinning triangle and text stretching!
-Step 2Proton stuff+Now let's do RTSimpleApp,​ same thing but it needs SDL2_mixer for its audio, so let's get that installed:
-  * Install linux tools for Windows, rsync and ssh should work from the command line +<code bash> 
-  * Setup a ssh key pair so you don't have to type passwords +sudo apt-get libsdl2-mixer-dev 
-  * Edit SetupVars.bat and edit the IP to the pi +</code>
-  * 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+
-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.+Great. ​ Now we compile and run like before, but we're adding a step - compiling media with the RTPack utility.
-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 ​bash
-<​code>​ +cd ~/​RTSimpleApp/​linux 
-sudo apt-get libsdl2-mixer-dev+sh 
 +cd ../media 
 +cd ../bin 
 </​code>​ </​code>​
-And that should compile ok. It should run 60+ fps at 720p on a Raspi 3. 
 +If that worked, enjoy the app.  If it didn'​t... off to the forums and yell at Seth!
