unexpected behavior of the example project's code after I commenting one line, build project, and then uncommenting it again

Question

Hi, I have a bit strange problems with example project "pwm_library". At first I compiled with segger embedded studio and ran the project on my NRF52-DK board, and it worked fine. Then i commented the line "#include "app_pwm.h"" just for the heck of it, to see what can happen, and tried to build the project. Obviously it failed. But then I uncommented the "#include "app_pwm.h"" line to restore my project and expected to see right behavior of the code. And it was completely unexpected, I got the same list of errors as before. Could you please tell me, what had happened to code, and how can I restore this example code. Thanks ahead.

Hey! thanx a lot for your post. I really appreciate it. I'm afraid, that situation is hopeless. But, I guess I partly understood what's happened to my code. The thing is that before I started to explore the "PWM library" example in such a way I explained above, I had been trying to combine two examples of SDK (SDK 17 and SES for ARM 4.12 by the way) "BLE_UART" and "PWM library". And, to be honest, I completely muddled up about all this stuff. That's why I decided to go back to the "PWM library" example" to try to understand what components of the project need to be added to the "BLE_UART" project to make it work together with "PWM library". But when I rebuilt my "PWM library" example project, it got previously corrupted shared files from SDK. I think it's too complicated for me to realize what exactly was broken. So, I ended up taking a new copy of the SDK and tried to combine these two examples again using all the new information I got surfacing the internet, and now this combination works well. I believe my first mistake was that I paid little attention to the configuration file, and then started to make stupid BS. I should've reported this earlier so as not to waste your time.
