Additional CMake Options for nRF Connect SDK project are not compiled

[Kiran S.]

Hello,

I am using Nordic's SES 4.52 with a project from nRF Connect SDK 1.3.1. I have preprocessor definitions I'd like to add to the project to mirror those added on the command line when the project is built in our source control/automated build system. The application needs the definition FIRMWARE_VERSION defined. So I added "-DFIRMWARE_VERSION=2.07.0" in the Additional CMake Options textbox under Tools->Options->nRF Connect. I've reloaded the project and confirmed what I entered is output as a part of the cmake command. But when I reference FIRMWARE_VERSION in my code, I get an error that it is undeclared. Same with CONFIG_FIRMWARE_VERSION. I thought this was the correct approach but perhaps there is a better way.

How does one successfully add preprocessor definitions to an nRF Connect SDK project in Nordic's SES?

Hi, Kiran!

Apologies for the late response to your case. We have documentation on how to modify and configure sample applications. It shows how you can add compilation options to your project, as well as changing the configuration. Could you try the approach described there and come back to me if you face any more issues?

For you information: the Additional CMake Options field is a bit misleading. SES will build the project environment using those options, but they will not necessarily apply to the actual builds that are flashed to a target. 

Best regards,
