To create a local clone of the source for the Azure Storage Client Library for C++ via git, type:
git clone https://github.com/Azure/azure-storage-cpp.git
cd azure-storage-cppTo install the binaries for the Azure Storage Client Library for C++, type the following into the NuGet Package Manager console:
Install-Package wastorage
To install the Azure Storage Client Library for C++ through Vcpkg, you need Vcpkg installed first. Please follow the instructions(https://github.com/Microsoft/vcpkg#quick-start) to install Vcpkg.
install package with:
C:\src\vcpkg> .\vcpkg install azure-storage-cpp
Starting from version 2.1.0, Azure Storage Client Library for C++ supports Visual Studio 2013 and Visual Studio 2015. In case you have the need to use Visual Studio 2012, please get version 2.0.0.
The Azure Storage Client Library for C++ depends on the C++ REST SDK (codename "Casablanca") 2.9.1. It can be installed through NuGet or downloaded directly from GitHub.
To get started with the coding, please visit the following articles:
- How to use Blob Storage from C++
- How to use Table Storage from C++
- How to use Queue Storage from C++
To accomplish specific tasks, please find the code samples at samples folder.
As mentioned above, the Azure Storage Client Library for C++ depends on Casablanca. Follow these instructions to compile it. Current version of the library depends on Casablanca version 2.9.1.
Once this is complete, then:
- Clone the project using git:
git clone https://github.com/Azure/azure-storage-cpp.gitThe project is cloned to a folder called azure-storage-cpp. Always use the master branch, which contains the latest release.
- Install additional dependencies:
sudo apt-get install libxml++2.6-dev libxml++2.6-doc uuid-dev- Build the SDK for Release:
cd azure-storage-cpp/Microsoft.WindowsAzure.Storage
mkdir build.release
cd build.release
CASABLANCA_DIR=<path to Casablanca> CXX=g++-4.8 cmake .. -DCMAKE_BUILD_TYPE=Release
makeIn the above command, replace <path to Casablanca> to point to your local installation of Casablanca. For example, if the file libcpprest.so exists at location ~/Github/Casablanca/cpprestsdk/Release/build.release/Binaries/libcpprest.so, then your cmake command should be:
CASABLANCA_DIR=~/Github/Casablanca/cpprestsdk CXX=g++-4.8 cmake .. -DCMAKE_BUILD_TYPE=ReleaseThe library is generated under azure-storage-cpp/Microsoft.WindowsAzure.Storage/build.release/Binaries/.
To build and run unit tests:
- Install UnitTest++ library:
sudo apt-get install libunittest++-dev- Build the test code:
CASABLANCA_DIR=<path to Casablanca> CXX=g++-4.8 cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTS=ON
make- Run unit tests
cd Binaries
vi test_configurations.json # modify test config file to include your storage account credentials
./azurestoragetestTo build sample code:
CASABLANCA_DIR=<path to Casablanca> CXX=g++-4.8 cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_SAMPLES=ON
makeTo run the samples:
cd Binaries
vi ../../samples/SamplesCommon/samples_common.h # modify connection string to include your storage account credentials
./samplesblobs # run the blobs sample
./samplesjson # run the tables sample with JSON payload
./samplestables # run the tables sample
./samplesqueues # run the queues samplePlease note the current build script is only tested on Ubuntu 14.04. Please update the script accordingly for other distributions.
Note that OSX is not officially supported yet, but it has been seen to work, YMMV. This build has been tested to work when the dependencies are installed via homebrew, YMMV if using FINK or MacPorts
Install dependecies with homebrew:
brew install libxml++ ossp-uuid openssl
As mentioned above, the Azure Storage Client Library for C++ depends on Casablanca. If you are using homebrew you can install it from there:
brew install cpprestsdk
Otherwise, you may need to build it. Follow these instructions to compile it. Current version of the library depends on Casablanca version 2.9.1.
Once this is complete, then:
- Clone the project using git:
git clone https://github.com/Azure/azure-storage-cpp.gitThe project is cloned to a folder called azure-storage-cpp. Always use the master branch, which contains the latest release.
Some notes about building:
-
If you're using homebrew, there seems to be an issue with the pkg-config files, which means that, by default, a -L flag to tell the linker where libintl lives is left out. We've accounted for this in our CMAKE file, by looking in the usual directory that homebrew puts those libs. If you are not using homebrew, you will get an error stating that you need to tell us where those libs live.
-
Similarly, for openssl, you don't want to use the version that comes with OSX, it is old. We've accounted for this in the CMAKE script by setting the search paths to where homebrew puts openssl, so if you're not using homebrew you'll need to tell us where a more recent version of openssl lives.
-
Build the SDK for Release if you are using hombrew:
cd azure-storage-cpp/Microsoft.WIndowsAzure.Storage
mkdir build.release
cd build.release
cmake .. -DCMAKE_BUILD_TYPE=Release
make- OR, Build the SDK for Release if you are not using homebrew
cd azure-storage-cpp/Microsoft.WindowsAzure.Storage
mkdir build.release
cd build.release
CASABLANCA_DIR=<path to casablanca> cmake .. -DCMAKE_BUILD_TYPE=Release -DOPENSSL_ROOT_DIR=<path to openssl> -DGETTEXT_LIB_DIR=<path to gettext lib dir>
makeIn the above command, replace:
<path to Casablanca>to point to your local installation of Casablanca. For example, if the filelibcpprest.soexists at location~/Github/Casablanca/cpprestsdk/Release/build.release/Binaries/libcpprest.dylib, then should be~/Github/Casablanca/cpprestsdk<path to openssl>to your local openssl, it is recommended not to use the version that comes with OSX, rather use one from Homebrew or the like. This should be the path that contains thelibandincludedirectories<path to gettext lib dir>is the directory which containslibintl.dylib
For example you might use:
CASABLANCA_DIR=~/Github/Casablanca/cpprestsdk cmake .. -DCMAKE_BUILD_TYPE=Release -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DGETTEXT_LIB_DIR=/usr/local/opt/gettext/libThe library is generated under azure-storage-cpp/Microsoft.WindowsAzure.Storage/build.release/Binaries/.
To build and run unit tests:
- Install UnitTest++ library:
brew install unittest-cpp- Build the test code:
cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTS=ON
make- Run unit tests
cd Binaries
vi test_configurations.json # modify test config file to include your storage account credentials
