CC1312R: Compile err: symbol "int" redefined

Frantisek Lysy

Part Number: CC1312R

Hello,

I'm working on a pretty large project based on the rfWsnNode example. Now I added my LED_signal library to this project. (I have used the LED_signal library before in other projects without problems). I am getting an compile error:

symbol "int" redefined: first defined in "./NodeTask.obj"; redefined in "C:/Users/.../Release/LED_signal.lib<led_signal.obj>" null: symbol "int" redefined: first defined in "./NodeTask.obj"; redefined in "C:/Users/.../Release/LED_signal.lib<led_signal.obj>"

Note that there is neither a procedure nor a function nor a variable nor a typedefs named 'int' in the project or in the library. I have read many advices on the forums but none of them helped me. I've been looking for the cause of the error for a long time and I don't know what to do next.

What is the best way to find similar errors in a large project?

(I°m sorry if the question is in the wrong forum)

Thank you very much for your help

Hi Frantisek,

Even though it is not the same objects and the issue, there is a similar issue with a repeated definition in a library and source code in an application.

This was fixed by changing the linking order of the files. Can you check the linking order of the files from other projects where you use the LED_signal library.

I have found some threads with similar scope.

Hi Sid,

Thank you for your response. I checked the linking order of the files from other projects where I use the LED_signal library and found no difference.

However, I was able to remove the error - the global variable 'uint8_t i' was forgotten in the NodeTask module. When I moved it into the appropriate function, the compile is without error. But I discovered this completely by coincidence when I was checking all the code in desperation. The exact name of the problematic variable in compile error description would help a lot.

But the most important for me is that the compile is without errors now.

Best regards

Frantisek
