#include "x.h" on source code and what about x.o?

Hi! Env: nrf51822

I am trying to add flash persistence to a working ble project.

In main .c I added: ...

  1. include "pstorage.h"
  2. define NEEDS_PSTORAGE 1
  3. include "nrf_error.h"

And I started to call functions like

pstorage_init() pstorage_register() Etc

When I compile I see errors like this:

Error: Undefined symbol pstorage_init() (referred from /build/./main..........).

It seems that project does not know the related implementation (.c or .o) right?

How to add implementation support to the pstorage module in mbed?

The needed files are in the project tree: ./nRF51822/source/nordic-sdk/components/drivers_nrf/pstorage/ config pstorage.c pstorage.h

In commandline nrf51 sdk / gcc, we add pstorage.c to the makefile. What about in mbed web IDE?

Thanks a lot

Extern C!!!

Did you add pstorage.c to the project in the web IDE?
