Unresolved symbol issue with Eclipse

Many users have reported this issue, but I cannot recall any solution to this. It seems this is just a "cosmetic" issue in Eclipse (compilation/build works fine). It might have to do with the fact that by following the tutorial, you are not creating a native Eclipse project, only running the makefile from Eclipse, and get the build output in the command window. We do not officially support the Eclipse editor, and encourage all our customer to use Segger Embedded Studio instead, which we provide a free licence for.

If you do find a solution to this issue in Eclipse, please post is here for other users to find it.

Hi Haaris, I am also using SEGGER Embedded Studio for debugging and compiling. However for code editing I still find Eclipse much better so I am trying to learn how to make it run smoothly.

I also wanted to use eclipse for this just like you because it's open source and was facing the same errors like "Symbols couldn't be resolved". SEGGER Embedded studio provides free license if you use a nordic device.

Sounds interesting. I will check that out. Thanks for the recommendation.

*Update: Ah I have checked out this option before. The problem with it is that it isn't free and I could not get the budget for it. But perhaps I should consider getting a personal embedded license.

Ah. Yes. Well, from my experience. That is the caveat of using Eclipse for this. :P

But after a year of struggling with it, I switched to VisualGDB. You should check it out. It is an amazingly fluent and simple experience compared to Eclipse.

Hi Abhishek, thanks for answering.

However I did include stdint.h and enable them in sdk_config.h. The project has compiled and work fine. The problem is that Eclipse still reports errors that the compiler never encounters.

Issue 1:

You should be able to solve it by including stdint.h in your main.c file. That’s what did the trick for me.

Issue 2:

When you use modules such as the PWM or the TIMER, you need to go to the sdk_config.h file for the project, located in the config folder, and enable the modules over there. That’ll make sure that the definitions for such things are present.

Hope this helps!
