-** Experimental and for linux pros only **
+** Compiling Proton and its examples on the Raspberry Pi with GL ES **
-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.
+As a base, I started with RetroPi on a Raspberry 3.  I should try it with a vanilla Raspbian Stretch install and see if that works too.
+First install Proton and compile its RTPack utility:
-Step 1: Make OpenGL ES 1/2 work on the Raspberry Pi 2 or 3.  Strangely, as of June 18th 2016 the versions you can get with apt-get are compiled with the wrong flags so it won't work with the hardware acceleration.  Useless.  So we will install our own SDL2.
+I ssh'ed in and did:
-I did this with the latest version of Raspbian (Jessie I think).
+<code bash>
+cd ~
+git clone https://github.com/SethRobinson/proton.git
-  * Give the video card more memory on the pi.  Run raspi-config and give it 128 or 256 (good for the pi3)
+//Build proton's RTPack tool
-  * Install cmake on the pi (sudo apt-get install cmake)
+cd ~/proton/RTPack/linux
-  * Do "sudo rpi-update" to make sure your firmware is updated
+sh linux_compile.sh
-  * Do the following from a shell window to install SDL2 from source:
+</code>
-<code>
+Now let's compile and run RTBareBones:
-cd ~
-sudo apt-get install libfreeimage-dev libopenal-dev libpango1.0-dev libsndfile1-dev libudev-dev libasound2-dev libjpeg-dev libtiff5-dev libwebp-dev automake
-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
+<code bash>
-sudo make install
+cd ~/proton/RTBareBones/linux
+sh linux_compile.sh
+cd ../bin
+./RTBareBones
 </code>
-To test your GL ES, do this with a local shell (not a remote shell window.. although maybe that works, dunno)
+If that worked, enjoy the spinning triangle and text stretching!
-<code>
-cd ~/SDL2-2.0.4/test
-g++ -o testgles2  testgles2.c `sdl2-config --cflags --libs`
-./testgles2
-</code>
-If stuff is setup right, you'll see some triangles or something rendering smoothly.
+Now let's do RTSimpleApp, same thing but it needs SDL2_mixer for its audio, so let's get that installed:
-Step 2: Proton stuff
+<code bash>
+sudo apt-get libsdl2-mixer-dev
+</code>
-  * Install linux tools for Windows, rsync and ssh should work from the command line
+Great.  Now we compile and run like before, but we're adding a step - compiling media with the RTPack utility.
-  * Setup a ssh key pair so you don't have to type passwords
-  * Edit SetupVars.bat and edit the IP to the pi
-  * Run CopyStuffToPi.bat.  There should now be a ~/proton tree on the pi
-  * RTBareBones/CopyStuffToPiAndCompileLoop.bat and it should update that example and compile it in a loop
+<code bash>
+cd ~/RTSimpleApp/linux
+sh linux_compile.sh
+cd ../media
+sh update_media.sh
+cd ../bin
+./RTSimpleApp
+</code>
-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.
+If that worked, enjoy the app.  If it didn't... off to the forums and yell at Seth!
