** Setting up Raspbery Pi to compile Proton SDK examples in X11 via SDL2 and the OpenGL experimental driver **
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 128 or 256 (good for the pi3)
* Also enable the experimental OpenGL driver under the Advanced section in raspi-config
* 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:
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
* Do the following from a shell window to install SDL2 from source:
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 --disable-pulseaudio --disable-esd --disable-video-mir --disable-video-wayland
make -j 5
sudo make install
* To test, type "glxgears" from a shell inside of the GUI desktop
Step 2: Proton stuff
* 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
* Edit SetupVars.bat and edit the IP to 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_OPENGL "Compile for Raspi 3 OpenGL" ON)" is uncommented
* 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.
