Raspberry Pi

• Prerequisites
• Build Kaa application

This guide explains how to cross-compile Kaa C SDK for Raspberry Pi. Alternatively, you can build the Kaa C SDK directly on the Raspberry Pi board. For more information, see Linux guide for Kaa C SDK.

NOTE: This guide is verified against:

• Host OS: Ubuntu 14.04 LTS Desktop 64-bit
• Device: Raspberry Pi 3
• Target OS: Raspbian Jessie

Prerequisites

Perform the following instructions on the host machine:

1. Install build prerequisites.

   sudo apt-get install cmake build-essential
   

2. Install toolchain.

   mkdir rpi_root && cd rpi_root
   git clone https://github.com/raspberrypi/tools.git
   export ARMLINUX_GCC=$(pwd)/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-gcc
   

Build Kaa application

After you installed the required dependencies and built the C SDK, you can build and run your Kaa application.

Since Raspberry runs on Linux, you can use the Linux guide to build and run your application.

NOTE: Make sure to specify correct compiler name when compiling your Kaa application for Raspberry Pi:

cmake -DKAA_MAX_LOG_LEVEL=3 -DCMAKE_C_COMPILER=$ARMLINUX_GCC -DBUILD_TESTING=OFF ..
make
