Trouble using Thinger and WiringPi to control LED

[TommyTsunami]

I posted this as a reply to another topic last week, but haven’t gotten any responses, so I’m going to try a new topic.

I’m trying to turn on an LED on a Raspberry Pi through Thinger with wiringPi. I got the Pi set up as a device following this guide:

Starting with the Raspberry Pi

[image] This how-to will cover how to get the first steps while using the thinger.io platform in the Raspberry Pi. This includes how to download, compile and execute the main example available in the GitHub Repository. Requirements A raspberry running with Raspbian, and a terminal or SSH access. Other OS like Ubuntu may work, but has not been tested yet. Register a device in the thinger.io console and keep the credentials by hand. If you need help with this part, please check this other how-…

I got the “sum” API working so I think the connection is good.
I also installed wiringPi and can make an LED blink with a simple c program, so I think it is properly installed. For whatever reason I can’t get the two to work together. I am trying to follow this post:

Figuring Out Thinger Platform To Control Raspberry Pi LED

Hello, for a college project we are using thinger.io for the first time and we’ve been studying manuals and resources about the possibilities with the platform. We’ve only had some experience with solely working with a Raspberry Pi and coding with Python. We have followed the Guide on how to establish a connection from the Raspberry Pi with the Thinger dashboard and this works 100%. Our project idea is to control a LED (on/off) from the platform and eventually expand towards the possibility o…

My problem is when I try to run it I get a bunch of “undefined reference” errors.

I did add -lwiringPi to the CMakeLists.txt.

I am new to all this so it’s probably something simple I’m missing, but I’d appreciate any pointers.
