Overview

mqtt_cpp is a header only library. It requires C++14 and the Boost Libraries 1.66.0 or later.

Add mqttcpp/include to your include path. Then, include `mqttcpp.hpp

and/or
mqttservercpp.hpp` as follows:

For clients: ```c++

include

include // if you want to use typical logging setup

For servers:
```c++
#include 
#include  // if you want to use typical logging setup

You can compile your code as follows:

g++ -std=c++14 -Ipath_to_mqtt_cpp/include your_program.cpp -pthread additional_options

additional_options

|what you want|required option| |---|---| |TLS support|

-DMQTT_USE_TLS -pthread -lssl -lcrypto
| |Logging support|
-DMQTT_USE_LOG -DBOOST_LOG_DYN_LINK -lboost_log -lboost_filesystem -lboost_thread

Example

Usage in cmake project

Add following lines to your

CMakeLists.txt
set(LIBNAME "your_project_name")
add_library(${LIBNAME} )

find_package(mqtt_cpp_iface REQUIRED) target_link_libraries(${LIBNAME} LINK_PUBLIC mqtt_cpp_iface::mqtt_cpp_iface)

This uses the

mqtt_cpp_iface::mqtt_cpp_iface
target and includes all necessary link dependencies.

Test

You can build tests and examples as follows:

At mqtt_cpp directory

mkdir build
cd build
cmake ..
make
make test

In order to build tests, you need to prepare the Boost Libraries 1.59.0.
