Eclipse unresolved symbols only for uintX_t and some macros

[Nathan O.]

Hi,

I am working on a project running on a nRF52832, using SDK 12.3 and S130. I use Eclipse (2018-12) as my IDE.

I have followed the explanations from this tutorial : https://devzone.nordicsemi.com/tutorials/b/getting-started/posts/development-with-gcc-and-eclipse

Unfortunately, I still have some "symbols could not be resolved" issues on the interface (the program does compile fine). I only see this error for some symbols like :

• uint32_t
• APP_ERROR_CHECK
• NRF_CLOCK_LFCLKSRC
• SOFTDEVICE_HANDLER_INIT
• APP_TIMER_TICKS

All the other SDK related symbols are found perfectly. The strangest thing is that Eclipse is able to find the symbols when I do a Ctrl+click it sends me to the corresponding definition source file.

Any idea ?

Hi,

The issue is most likely that the standard toolchain paths have not been added to the project. It should happen automatically once you enable the "CDT GCC Built-in Compiler settings" provider:

To confirm this, try to expand provider like shown below, and see if it includes paths to your toolchain.

Thanks for your answer.

Here is my config below. It seems that the output parser is not working well.

You should have had a lot more errors if the output parser didn't work. A re-build might help.

Can you expand the "CDT GCC Built-in Compiler settings" entry in your 2nd screenshot and see if it includes your toolchain paths?

I have done several rebuild and refresh of the index. I has not helped.

It seems to include the toolchain path :

Strange, the paths appear to be correct. Are you still getting the "unresolved error" for uint32_t? Also, have you replaced makefile.common with the one I included in the tutorial?
