Raspberry Pi 3 Notes

Requirements

  • Raspbian Jessie or later
  • CMake 3.0+

CMake

To install CMake:

sudo apt-get install cmake

Cinder Dependencies

sudo apt-get install libxcursor-dev \
libgles2-mesa-dev \
zlib1g-dev \
libfontconfig1-dev \
libmpg123-dev \
libsndfile1 \
libsndfile1-dev \
libpulse-dev \
libasound2-dev \

libgstreamer-plugins-bad1.0-dev \
libgstreamer-plugins-base1.0-dev \
gstreamer1.0-libav \

gstreamer1.0-plugins-bad

Building Cinder

Fetching and Building Cinder

git clone --recursive https://github.com/cinder/Cinder.git
cd Cinder
mkdir build && cd build
cmake .. -DCINDER_TARGET_GL=es2-rpi
make -j 3

NOTE: Attempting to build Cinder with more than 3 jobs (specified with the -j 3 parameter) will likely cause a hard crash due to GCC memory requirements.

Clang

Cinder can also be used with the version of Clang (v3.5.0) packaged for Raspbian Jessie. Install it using apt-get:

sudo apt-get install clang

To set Clang as the default compiler, select /usr/bin/clang++ when prompted by this command:

sudo update-alternatives --config c++

Building and Running BasicApp

Building

cd samples/BasicApp/proj/cmake
mkdir build && cd build
cmake .. -DCINDER_TARGET_GL=es2-rpi
make

Running

Starting from samples/BasicApp/proj/cmake/build:

./Debug/BasicApp

Exiting

Hit the Esc key to exit the BasicApp. Cinder for Linux on the Raspberry Pi 3 currently has Esc hardcoded to exit an application. Otherwise it's non-trivial to return to the OS. A future version will offer a more graceful way to handle this.

Troubleshooting

Audio

No Output Using 3.5mm headphone jack

Try the following, it will force output to the 3.5mm jack (more information here):

sudo amixer cset numid=3 1
