Lesson learned on removing compiler define flags from subfolders within a project

[elsevers]

Problem

We recently had an issue where we wanted to disable the blink app. We tried to do this by removing the compiler define flag for APP_BLINK (i.e., reversing the procedure here).

However, this did not have intended effect. The blink app continued to be built and run.

Solution

Upon inspecting the .cproject file, we were able to see that the compiler define flag was actually still in effect on subfolders within the app_cpu1 project:

• app_cpu1\usr
• app_cpu1\currentRegulator

We had to go to properties on each of these folders individually to remove it:

We don't know how the setting got there in the first place (on these subfolder).

Takeaway

The lesson learned here is that it is possible to set compiler flags on a per-folder basis within each project. User beware
