### Raspberry Pi example
To cross compile example for Raspberry Pi you will need [RPi toolchain](https://github.com/raspberrypi/tools/tree/master/arm-bcm2708) and [userspace libraries](https://github.com/raspberrypi/firmware) (opt/vc).
Export path to RPi toolchain:
export RPI_HOME=/opt/tools/arm-bcm2708/arm-linux-gnueabihf
Add toolchain bin directory to PATH:
export PATH=${RPI_HOME}/bin:${PATH}
And compile example:
CC=arm-linux-gnueabihf-gcc \
CGO_CFLAGS="-I/opt/vc/include -I/opt/vc/include/interface/vcos -I/opt/vc/include/interface/vmcs_host/linux -I/opt/vc/include/interface/vcos/pthreads --sysroot=${RPI_HOME}/arm-linux-gnueabihf/sysroot" \
