Azure Storage Client Library for C++

The Azure Storage Client Library for C++ allows you to build applications against Microsoft Azure Storage. For an overview of Azure Storage, see Introduction to Microsoft Azure Storage.

Features

• Blobs
  • Create/Delete/List Containers
  • Create/Read/Update/Delete/List Blobs
• DataLake Gen 2
  • Create/Delete File Systems
  • Create/Delete Directories
  • Create/Read/Append/Flush/Delete Files
• File Shares
  • Create/Delete Shares
  • Create/Delete Directories
  • Create/Read/Delete Files

Getting started

For the best development experience, we recommend that developers use the CMake projects in Visual Studio to view and build the source code together with its dependencies.

Requirements

To call Azure services, you must first have an Azure subscription. Sign up for a free trial or use your MSDN subscriber benefits.

Need Help?

Be sure to check out the Azure Storage Forum on MSDN if you need help, or use StackOverflow.

Collaborate & Contribute

We gladly accept community contributions.

• Issues: Report bugs on the Issues page in GitHub. Ideally, please add an "[Storage]" prefix to the title for easier categorizing.
• Forums: Communicate with the Azure Storage development team on the Azure Storage Forum or StackOverflow.
• Source Code Contributions: Please follow the contribution guidelines for Azure open source for instructions about contributing to the source project.

Download & Install

Install Dependencies

Windows

On Windows, dependencies are managed by vcpkg. You can reference the Quick Start to quickly set yourself up. After Vcpkg is initialized and bootstrapped, you can install the dependencies:

vcpkg.exe install libxml2:x64-windows-static curl:x64-windows-static

POSIX Platforms

You can use the package manager on different POSIX platforms to install the dependencies. The dependencies to be installed are:

• CMake 3.13.0 or higher.
• libxml2.
• OpenSSL.
• libcurl.

Build from Source

First, download the repository to your local folder:

git clone https://github.com/Azure/azure-sdk-for-cpp.git

Windows

Use CMake to generate the solution file

In a new folder you created under the root directory:

cmake .. -A x64 -DCMAKE_TOOLCHAIN_FILE=<YOUR_VCPKG_INSTALL_DIR>/scripts/buildsystems/vcpkg.cmake
cmake --build .

The built library will be in .\sdk\<ProjectDir>\<Configuration>\ respectively for Azure Core and Azure Storage. e.g. azure_core.lib will be in .\sdk\core\azure-core\Debug for debug configuration.

Use Visual Studio's Open by folder feature

Open the root folder of the library with Visual Studio's Open folder feature.

If Vcpkg is not globally integrated, then you need to open CMakeSettings.json and change the Make toolchain file to be <YOUR_VCPKG_INSTALL_DIR>/scripts/buildsystems/vcpkg.cmake and save. Then you can build Azure Storage libraries by selecting the target in Visual Studio, or simply build all. The libraries will be in <ProjectRoot>\out\build\<Configuration>\sdk\<LibraryName> respectively.

POSIX Platforms

You can run the following command in a new folder created under the downloaded code's root folder to build the code.

cmake .. -DCMAKE_BUILD_TYPE=Debug
cmake --build .

Then you can consume the built library with the header files. make/ninja install is work in progress.

Via NuGet

WIP TODO when ready.

Via vcpkg

The easiest way to acquire the C++ SDK is leveraging vcpkg package manager. See the corresponding Azure SDK for C++ readme section.

To install Azure Storage packages via vcpkg:

> vcpkg install azure-storage-blobs-cpp azure-storage-files-datalake-cpp azure-storage-files-shares-cpp

Then, use in your CMake file:

find_package(azure-storage-blobs-cpp CONFIG REQUIRED)
target_link_libraries(<your project name> PRIVATE Azure::azure-storage-blobs)

find_package(azure-storage-files-datalake-cpp CONFIG REQUIRED)
target_link_libraries(<your project name> PRIVATE Azure::azure-storage-files-datalake)

find_package(azure-storage-files-shares-cpp CONFIG REQUIRED)
target_link_libraries(<your project name> PRIVATE Azure::azure-storage-files-shares)

Dependencies

• Azure Core SDK
• libxml2
