• 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.

Getting Started on Linux

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 2.8.0.

Once this is complete, then:

• Clone the project using git:

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

The 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
make

In 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=Release

The 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
./azurestoragetest

To build sample code:

CASABLANCA_DIR=<path to Casablanca> CXX=g++-4.8 cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_SAMPLES=ON
make

To run the samples:

cd Binaries
./samplesblobs            # run the blobs sample
./samplesjson             # run the tables sample with JSON payload
./samplestables           # run the tables sample
./samplesqueues           # run the queues sample

Please note the current build script is only tested on Ubuntu 14.04. Please update the script accordingly for other distributions.
