AWS IoT SDK for C++ v2

This document provides information about the AWS IoT device SDK for C++ V2.

If you have any issues or feature requests, please file an issue or pull request.

This SDK is built on the AWS Common Runtime, a collection of libraries (aws-c-common, aws-c-io, aws-c-mqtt, aws-c-http, aws-c-cal, aws-c-auth, s2n...) written in C to be cross-platform, high-performance, secure, and reliable. The libraries are bound to C++ by the aws-crt-cpp package.

Installation

Minimum Requirements

• C++ 11 or higher
• CMake 3.1+
• Clang 3.9+ or GCC 4.4+ or MSVC 2015+

Build from source

Automatically Build and Install AWS Dependencies

mkdir sdk-cpp-workspace
cd sdk-cpp-workspace
git clone --recursive https://github.com/aws/aws-iot-device-sdk-cpp-v2.git
mkdir aws-iot-device-sdk-cpp-v2-build
cd aws-iot-device-sdk-cpp-v2-build
cmake -DCMAKE_INSTALL_PREFIX="<absolute path sdk-cpp-workspace dir>"  -DBUILD_DEPS=ON ../aws-iot-device-sdk-cpp-v2
cmake --build . --target install

Using a Pre-Built aws-crt-cpp (Most useful for development of this package)

mkdir aws-iot-device-sdk-cpp-v2-build
cd aws-iot-device-sdk-cpp-v2-build
cmake -DCMAKE_INSTALL_PREFIX="<absolute path sdk-cpp-workspace dir>"  -DCMAKE_PREFIX_PATH="<absolute path sdk-cpp-workspace dir>" -DBUILD_DEPS=OFF ../aws-iot-device-sdk-cpp-v2
cmake --build . --target install

Building on Windows

Due to maximum path length limitations in the Windows API, we recommend enabling long paths on your development machines, or cloning to a short path like: C:\dev\iotsdk

Mac-Only TLS Behavior

Please note that on Mac, once a private key is used with a certificate, that certificate-key pair is imported into the Mac Keychain. All subsequent uses of that certificate will use the stored private key and ignore anything passed in programmatically. Beginning in v1.7.3, when a stored private key from the Keychain is used, the following will be logged at the "info" log level:

static: certificate has an existing certificate-key pair that was previously imported into the Keychain.  Using key from Keychain instead of the one provided.
