LPCXpresso add header file to include path

mateuszkiełbasa — Tue, 07 Feb 2017 14:55:34 GMT

I would like to add simple own library to project include path. Project structure (I created folder delay)

-project

-Includes

-src

-Debug

-delay

-inc

-delay.h

-src

-delay.c

In project.c I added #include "inc/delay.h"

I added new include path in MCU C Compiler -> Includes -> Include path like this: "${workspace_loc:/project/delay}". When I try to Build it I get error:

/home/user/LPCXpresso/workspace/project/Debug/../src/project.c:41: undefined reference to `Delay_Init'
/home/user/LPCXpresso/workspace/project/Debug/../src/project.c:47: undefined reference to `Delay'

Delay_Init and Delay was created in delay.h and delay.c

Specify the directories where the include files are. So if it is in delay/inc, the add delay/inc, not just delay as you have done.

Hi Mateusz,

Con Verse's reply is correct, your head file in under delay/inc, so you still need to add /inc.

Please add it and try again.

Wish it helps you!

If you still have question, please let me know!

Have a great day,
Kerry

For including a header to a file,

Go to: Project -> Properties ---> Select "Project Reference under the left tab", select the board and chip header files.
