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 \

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

libboost-filesystem-dev

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

Starting the pulsedeamon

Raspbian ships with Pulse Audio installed, however you must start the pulsedeamon before you can use audio in your application. Do that by running the following:

pulseaudio -D

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
