Paho MQTT-C API
« on: June 05, 2020, 09:53:38 pm »
HI there,
I am quite new to CodeBlock and I have refreshed myself using C/C++ language (I am more a Matlab guy).
I am interested in using the MQTT API from Paho: https://www.eclipse.org/paho/clients/c/#

I am using one of the example given in the examples of the API : https://www.eclipse.org/paho/files/mqttdoc/MQTTClient/html/subasync.html

I understand there is a .lib folder I need to integrate to my project. I added it using : Project > Build Option > Linker Settings > Add... 


Do you know how can I link to the folder containing the headers files?  "MQTTClient.h" ?

 First you have to build the library, and install it.
Then you probably get something like
Code: [Select]
installDir:
 |- bin
 |- lib
 |   |- somelibraryname.a
 | - include
     |- someheader.h

To use this library in your codeblocks project you do the following:
1) Setup the project build options:
1.1) Project->Build options->Select your project name on the left
1.2) Search directories-> Compiler
1.3) Add the include directory for the library
1.4) Search directories->Linker
1.5) Add the lib folder for the library
1.6) Linker settings->Add - the .lib file you can only the name, because you have added the folder to the search directories...

now you should be able to use it in your project.
