Microsoft Azure MQTT

azure-umqtt-c is a C library for MQTT 3.1 protocol communication to Azure Cloud IoT Services.

Dependencies

azure-mqtt client use the azure-c-shared-utility, which is a C library provisioning common functionality for basic tasks (like string, list manipulation, IO, etc.). azure-c-shared-utility is available here: https://github.com/Azure/azure-c-shared-utility. azure-c-shared-utility needs to be built before building azure-mqtt-c.

Setup

Build

• Clone azure-umqtt-c by:

git clone https://github.com/Azure/azure-umqtt-c.git
cd azure-umqtt-c
git submodule update --init

• Create a folder cmake under azure-umqtt-c

• Switch to the cmake folder and run

cmake ..

• Build

cmake --build .

Installation and Use

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

1. Switch to the cmake folder and run

   cmake -Duse_installed=ON ../
   cmake --build . --target install

   or install using the follow commands for each platform:

   On Linux:

   sudo make install

   On Windows:

   find_package(umqtt REQUIRED CONFIG)
   target_link_library(yourlib umqtt)

This requires that azure-c-shared-utility is installed (through CMake) on your machine.

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
