Undefined reference problem

[rfeichubuinm]

Hi everyone! I'll keep it as short as possible...

I am getting these errors:

• I've already included #include "app_ADC.h" in both main.c and app_ADC.c
• Both, header and source files, are located in folder Application.
• I've already added the include paths to the compiler, libraries to the linker and the paths to paths and symbols.

• I'm using MCUXpresso IDE v11.0.1 [Build 2563].

Any suggestion?

Thanks a lot.

Hi Ramiro,

I guess app_ADC_init is not compiled. The .c file which has the app_ADC_init is not add into make list. You can write any wrong letter in to app_ADC_init and compile again. If the compiler does not report error, that is it.

Please delete that folder from project then add again. Please add in this way

 

Regards,

Jing

Also confirms this works.  I was copying a "video" folder from another project over, and got the same error.  Creating the source folder then copying the files is the way to go.
