multiple definition errors while building PIC24 based project

Posted by themadmstrmnd on February 11, 2016

I am getting multiple definition errors while building a project for a PIC24 platform. The functions the compiler is erroring on is found in list.c. I can't think why this is happening. list.h is of course protected from the ifndef LIST_H. The FreeRTOS files have not been modified.

I am using version 8.2.3

Hi Nick,

Are you sure you didn't include the list.o module two times?

Can you check the complete command that is issued for linking?

I think it's got nothing to do with the header file list.h: those are only function prototypes like this one:

~~~~ void vListInitialise( Listt * const pxList ) PRIVILEGEDFUNCTION; ~~~~

Did you define PRIVILEGED_FUNCTION somehow?

Regards.
