Compilation error while building Azure IoT SDK when adding "-DUSE_PROV_MODULE" in azureiot.bld file

[MrudulaSatyaY]

Hello,

I am using the TI CC3235SF MCU and to include the Azure IoT SDK, I am using the Azure IoT SDK Plugin V4.10 provided by TI. Into this plugin, I have cloned the latest LTS Azure IoT SDK C ([LTS_03_2024_Ref02).

I am using XDC Tools 3.61.00.16_core.

When I try to build the Azure IoT SDK with "-DUSE_PROV_MODULE" in the azureiot.bld file, (code snippet below)
"ti.targets.arm.elf.M4" : " -ms -g --c99 -DUSE_PROV_MODULE",

I am getting a compilation error. Without the "-DUSE_PROV_MODULE" macro, the SDK builds fine.

But I need to use the Device Provisioning Service (DPS) code and hence I need to use this macro.

The compilation error is as follows:

The compilation error occurs in the iothub_client_authorization.c file.

I am not sure if this is a Azure IoT SDK C issue or an XDC tools issue or a TI issue. hence, I decided to start here and posting my query.

Thank you in advance.

Hello,

I was able to resolve this issue by making the following change in iothub_client_authorization.c file line 18.

As the issue was "cannot open

", I mentioned the whole path of the headerfile iothub_auth_client.h instead of the relative path that is mentioned in line 18. This resolved the compilation error.

Is this something important for which I need to issue a pull request ?

Hi @MrudulaSatyaY , thank you for the issue and sharing the details for the workaround.
We will try to add your fix to the code base, but meanwhile I wanted to check if you got to play with our other SDK specifically designed for microcontrollers? Please check it out: https://github.com/azure/azure-sdk-for-c

[MrudulaSatya]

Hi @ewertons
Thank you for your response. I will definitely checkout the SDK for embedded systems.
