Linker unable to find function definition despite .c file being in the project and .h file included

[CLEC]

Hi,

I encountered an issue when moving my project directory within my computer.
In fact, the linker seems to be unable to find some functions definitions :

Error[Li005]: no definition for "app_uart_init" [referenced from .....\main.o]
Error[Li005]: no definition for "app_uart_put" [referenced from .....\main.o]

These functions are defined in app_uart_fifo.c and the source file is included in my project workspace.


My investigations have shown that the first if condition of the source file is not working as expected:

#if NRF_MODULE_ENABLED(APP_UART)
...
app_uart_init definition
app_uart_put definition

...

#endif

Thus I checked if APP_UART_ENABLED was defined, and its defintion can be found in sdk_config.h which also is included within my project workspace.
Bypassing this if condition only creates more errors as some identifiers are undefined.

I don't know anymore what to try in order to fix my issue, any idea ?
(FYI I am working on IAR 8.50.6.28951)

Thanks in advance for your help !

Hello again !

As you can see, sdk_config.h is well included within app_uart_fifo.c, but as you mentionned this file was different from the one included in my project.



Unfortunately, including the right file has not fixed the problem. (The errors are exactly the same)
Again, thanks for your time !

Hello,

Where was the other instance of the sdk_config.h header located? Can you try removing it and see if it helps? As all defines are guarded with #ifndef's, it could be a problem if these symbols are defined elsewhere in your code.
