Azure C Shared Utility

azure-c-shared-utility is a C library providing common functionality for basic tasks (like string, list manipulation, IO, etc.).

Dependencies

azure-c-shared-utility provides 3 tlsio implementations:

• tlsio_schannel - runs only on Windows
• tlsio_openssl - depends on OpenSSL being installed
• tlsio_wolfssl - depends on WolfSSL being installed

azure-c-shared-utility depends on curl for HTTPAPI for Linux.

azure-c-shared-utility uses cmake for configuring build files.

Setup

1. Clone azure-c-shared-utility using the recursive option:

git clone --recursive https://github.com/Azure/azure-c-shared-utility.git

2. Create a folder called cmake under azure-c-shared-utility

3. Switch to the cmake folder and run

cmake ..

4. Build

cmake --build .

Installation and Use

Optionally, you may choose to install azure-c-shared-utility on your machine:

1. Switch to the cmake folder and run

   cmake -Duse_installed_dependencies=ON ../
   

   cmake --build . --target install
   

   or install using the follow commands for each platform:

   On Linux:

   sudo make install
   

   On Windows:

   msbuild /m INSTALL.vcxproj
   

2. Use it in your project (if installed)

   find_package(azure_c_shared_utility REQUIRED CONFIG)
   target_link_library(yourlib aziotsharedutil)
   

If running tests, this requires that umock-c, azure-ctest, and azure-c-testrunnerswitcher are installed (through CMake) on your machine.

Building the tests

In order to build the tests use:

cmake .. -Drun_unittests:bool=ON

Configuration options

In order to turn on/off the tlsio implementations use the following CMAKE options:

• -Duse_schannel:bool={ON/OFF} - turns on/off the SChannel support
• -Duse_openssl:bool={ON/OFF} - turns on/off the OpenSSL support. If this option is use an environment variable name OpenSSLDir should be set to point to the OpenSSL folder.
• -Duse_wolfssl:bool={ON/OFF} - turns on/off the WolfSSL support. If this option is use an environment variable name WolfSSLDir should be set to point to the WolfSSL folder.
• -Duse_http:bool={ON/OFF} - turns on/off the HTTP API support.
• -Duse_installed_dependencies:bool={ON/OFF} - turns on/off building azure-c-shared-utility using installed dependencies. This package may only be installed if this flag is ON.
• -Drun_unittests:bool={ON/OFF} - enables building of unit tests. Default is OFF.
