Compiling Proton and its examples on the Raspberry Pi with GL ES

As a base, I started with a RetroPi image written to an SD card (tested with 4.4 on 1/28/2019) on a Raspberry 3B. Why? Because it comes with SDL2 pre-installed and pre configured so SDL will properly send mouse and keyboard input which saves a lot of hassle. (don't ask me why, but the version the standard stretch has on apt-get doesn't)

If you REALLY want to use a standard Raspbian stretch install you can, just do these commands first to get ready:

sudo apt-get install cmake
sudo apt-get install libsdl2-2.0-0 libsdl2-dev

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.

First, make sure you gave git installed. SSH into your PI and:

sudo apt-get install git

Next, install Proton and compile its RTPack utility:

cd ~
git clone https://github.com/SethRobinson/proton.git

Now let's build Proton's RTPack utility, will come in handle later.

cd ~/proton/RTPack/linux
sh linux_compile.sh

Now let's compile and run RTBareBones:

cd ~/proton/RTBareBones/linux
sh linux_compile.sh
cd ../bin
./RTBareBones

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:

sudo apt-get install libsdl2-mixer-dev

Great. Now we compile and run like before, but we're adding a step - compiling media with the RTPack utility.

cd ~/RTSimpleApp/linux
sh linux_compile.sh
cd ../media
sh update_media.sh
cd ../bin
./RTSimpleApp

If that worked, enjoy the app. If it didn't… off to the forums and yell at Seth!
