AWS SDK for C++  1.8.53
AWS SDK for C++
AWS SDK for C++

The AWS SDK for C++ provides a modern C++ (version C++ 11 or later) interface for Amazon Web Services (AWS). It is meant to be performant and fully functioning with low- and high-level SDKs, while minimizing dependencies and providing platform portability (Windows, OSX, Linux, and mobile).

AWS SDK for C++ is in now in General Availability and recommended for production use. We invite our customers to join the development efforts by submitting pull requests and sending us feedback and ideas via GitHub Issues.

Version 1.8 is now Available!

Version 1.8 introduces much asked for new features and changes to the SDK but, because this might also cause compatibility issues with previous versions we've decided to keep it as a seperate branch to make the transition less jarring.

For more information see the What’s New in AWS SDK for CPP Version 1.8 entry of the wiki, and also please provide any feedback you may have of these changes on our pinned issue.

Getting Started

Building the SDK:

Minimum Requirements:

Building From Source:

To create an out-of-source build:

  1. Install CMake and the relevant build tools for your platform. Ensure these are available in your executable path.
  2. Create your build directory. Replace <BUILD_DIR> with your build directory name:
  3. Build the project:
    • For Auto Make build systems:
      cd <BUILD_DIR>
      cmake <path-to-root-of-this-source-code> -DCMAKE_BUILD_TYPE=Debug
      make
      sudo make install
    • For Visual Studio:
      cd <BUILD_DIR>
      cmake <path-to-root-of-this-source-code> -G "Visual Studio 15 Win64" -DCMAKE_BUILD_TYPE=Debug
      msbuild ALL_BUILD.vcxproj /p:Configuration=Debug
    • For macOS - Xcode:
      cmake <path-to-root-of-this-source-code> -G Xcode -DTARGET_ARCH="APPLE" -DCMAKE_BUILD_TYPE=Debug
      xcodebuild -target ALL_BUILD

Third party dependencies:

Starting from version 1.7.0, we added several third party dependencies, including aws-c-common, aws-checksums and aws-c-event-stream. By default, they will be built and installed in <BUILD_DIR>/.deps/install, and copied to default system directory during SDK installation. You can change the location by specifying CMAKE_INSTALL_PREFIX.

However, if you want to build and install these libraries in custom locations:

  1. Download, build and install aws-c-common:
    git clone https://github.com/awslabs/aws-c-common
    cd aws-c-common
    # checkout to a specific commit id if you want.
    git checkout <commit-id>
    mkdir build && cd build
    # without CMAKE_INSTALL_PREFIX, it will be installed to default system directory.
    cmake .. -DCMAKE_INSTALL_PREFIX=<deps-install-dir> <extra-cmake-parameters-here>
    make # or MSBuild ALL_BUILD.vcxproj on Windows
    make install # or MSBuild INSTALL.vcxproj on Windows
  2. Download, build and install aws-checksums:
    git clone https://github.com/awslabs/aws-checksums
    cd aws-checksums
    # checkout to a specific commit id if you want
    git checkout <commit-id>
    mkdir build && cd build
    # without CMAKE_INSTALL_PREFIX, it will be installed to default system directory.
    cmake .. -DCMAKE_INSTALL_PREFIX=<deps-install-dir> <extra-cmake-parameters-here>
    make # or MSBuild ALL_BUILD.vcxproj on Windows
    make install # or MSBuild INSTALL.vcxproj on Windows
  3. Download, build and install aws-c-event-stream:
    git clone https://github.com/awslabs/aws-c-event-stream
    cd aws-c-event-stream
    # checkout to a specific commit id if you want
    git checkout <commit-id>
    mkdir build && cd build
    # aws-c-common and aws-checksums are dependencies of aws-c-event-stream
    # without CMAKE_INSTALL_PREFIX, it will be installed to default system directory.
    cmake .. -DCMAKE_INSTALL_PREFIX=<deps-install-dir> -DCMAKE_PREFIX_PATH=<deps-install-dir> <extra-cmake-parameters-here>
    make # or MSBuild ALL_BUILD.vcxproj on Windows
    make install # or MSBuild INSTALL.vcxproj on Windows
  4. Turn off BUILD_DEPS when building C++ SDK:
    cd BUILD_DIR
    cmake <path-to-root-of-this-source-code> -DBUILD_DEPS=OFF -DCMAKE_PREFIX_PATH=<deps-install-dir>

Other Dependencies:

To compile in Linux, you must have the header files for libcurl, libopenssl. The packages are typically available in your package manager.

Debian example: sudo apt-get install libcurl-dev

Building for Android

To build for Android, add -DTARGET_ARCH=ANDROID to your cmake command line. Currently we support Android APIs from 19 to 28 with Android NDK 19c and we are using build-in cmake toolchain file supplied by Android NDK, assuming you have the appropriate environment variables (ANDROID_NDK) set.

Android on Windows

Building for Android on Windows requires some additional setup. In particular, you will need to run cmake from a Visual Studio developer command prompt (2015 or higher). Additionally, you will need 'git' and 'patch' in your path. If you have git installed on a Windows system, then patch is likely found in a sibling directory (.../Git/usr/bin/). Once you've verified these requirements, your cmake command line will change slightly to use nmake:

cmake -G "NMake Makefiles" `-DTARGET_ARCH=ANDROID` <other options> ..

Nmake builds targets in a serial fashion. To make things quicker, we recommend installing JOM as an alternative to nmake and then changing the cmake invocation to:

cmake -G "NMake Makefiles JOM" `-DTARGET_ARCH=ANDROID` <other options> ..

Building for Docker

To build for Docker, ensure your container meets the minimum requirements. By default, Docker Desktop is set to use 2 GB runtime memory. We have provided Dockerfiles as templates for building the SDK in a container.
