Build legato app using Azure IoT SDK FX30 (WP7702)

Hi all,

I’ve been struggling for 2 weeks to build a legato app, integration the azure iot sdk. My end goal, is to send a message to our IOT Hub.

I am able to build and run a basic Legato app, but I can’t seem to compile the Azure IoT SDK:

Does anyone have any experience with this?

I am getting the following build errors, when trying to compile:
