-** 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 (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.
-Steps:
+Update on Jan 28th 2019:  I did try this with Raspbian Stretch 4.14, you need to run these commands first to get it working:
-* 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 install git
-* Edit SetupVars.bat and edit the IP to the pi
+sudo apt-get install cmake
-* Install development tools on the pi (sudo apt-get update && apt-get install build-essential)
+sudo apt-get install libsdl2-2.0-0 libsdl2-dev
-* Run CopyStuffToPi.bat.  There should now be a ~/proton tree on the pi
+</code>
-* RTBareBones/CopyStuffToPiAndCompileLoop.bat and it should update that example and compile it in a loop
+Also, I think the GL driver needs to be set to "Legacy" to work, which is the default, but worth mentioning if you've changed it using raspi-config.
-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.
+---- End Raspbian stretch part ----
+First install Proton and compile its RTPack utility:
+I ssh'ed in and did:
+<code bash>
+cd ~
+git clone https://github.com/SethRobinson/proton.git
+</code>
+Now let's build Proton's RTPack utility, will come in handle later.
+<code bash>
+cd ~/proton/RTPack/linux
+sh linux_compile.sh
+</code>
+Now let's compile and run RTBareBones:
+<code bash>
+cd ~/proton/RTBareBones/linux
+sh linux_compile.sh
+cd ../bin
+./RTBareBones
+</code>
+If that worked, enjoy the spinning triangle and text stretching!
+Now let's do RTSimpleApp, same thing but it needs SDL2_mixer for its audio, so let's get that installed:
+<code bash>
+sudo apt-get install libsdl2-mixer-dev
+</code>
+Great.  Now we compile and run like before, but we're adding a step - compiling media with the RTPack utility.
+<code bash>
+cd ~/RTSimpleApp/linux
+sh linux_compile.sh
+cd ../media
+sh update_media.sh
+cd ../bin
+./RTSimpleApp
+</code>
+If that worked, enjoy the app.  If it didn't... off to the forums and yell at Seth!
+=== State of Proton on the Pi ===
+  - It runs fullscreen only both in or out of the desktop environment
+  - No mouse or keyboard input (SDL isn't doing its job, see below)
+  - Video acceleration works, audio works (see my [[https://www.youtube.com/watch?v=bk6jVk7t4i4|Atari PaperCart project]])
+SDL apparently can be tweaked to actually work with mouse and keyboard input but it requires some tricky stuff [[https://hg.libsdl.org/SDL/file/093b58f5de3c/docs/README-raspberrypi.md|last I checked]].  Might be easier for Proton to just do its own input handling via libudev/libusb or something, not sure.
