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 ?

Yes I'm still getting the errors, although it's only errors in the Eclipse UI. The project actually builds fine.

I have replaced the double quotes by single quotes. I have again tested with both solution (single and double) and am having the same results. I also checked with the Makefile.common included in the tutorial and it is effectively the same as the one I have where I changed to have single quotes.

This does seem to be a "feature" of Eclipse - I've seen it in a number of other applications of Eclipse.

(to be fair, Eclipse is not alone - Visual Studio & derivatives have similar  issues)

Perhaps Nguyen Hoan Hoang - the resident Eclipse expert & proponent - can help ... ?

Hi,

I've already fixed this issue in the past. Check this post:

Thanks. I have tried two times the whole process of restoring default, checking each element as you indicated in your post but I still have the same issue.

You can try this:

Go to Project Properties->C/C++ Build->Preprocessor Include Paths,..->Entries->GNU C and add the include paths to the CDT User Setting Entries. The include paths are (they sadly aren't carried with the project settings):

• {path to gcc-arm-none-eabi}/arm-none-eabi/include
• {path to gcc-arm-none-eabi}/lib/gcc/arm-none-eabi/{version}/include
