multiple definition of "something" Segger

[NMD]

Hello every one.

I am new with Segger and nRF52.

I tried to create my own library for OB1203 sensor.

But i stack here when Segger view this error:

Output/blinky_pca10040_s132 Release/Obj/OB1203.o:C:\Users\dang\Desktop\OB1203v1\examples\peripheral\blinky\pca10040\s132\ses/../../../../../../modules/nrfx/drivers/include/OB1203.h:195: multiple definition of `osc_trim'; Output/blinky_pca10040_s132 Release/Obj/main.o:C:\Users\dang\Desktop\OB1203v1\examples\peripheral\blinky\pca10040\s132\ses/../../../../../../modules/nrfx/drivers/include/OB1203.h:195: first defined here

Below is my screen shoot

I believe the way i put OB1203.h and OB1203.c is wrong, that is not relate to Segger or nRF52 but i can not find where it wrong. 

Please help me.

Thank you for any support

Hi

According to the SEGGER error, it seems that you have defined the same function/variable "osc_trim" multiple times. Please try removing one of the defines to avoid getting this error. I'm guessing you have defined it in both the header and .c file. Please check it out and try again.

Best regards,

Thank you for your help.

I double checked my project. But "osc_trim" variable is only in OB1203.h file

Follow the SEGGER error both file SEGGER said multiple definition is OB1203.h file, means one file. That one is not make sense to me. Do you have any else ideal.

Output/blinky_pca10040_s132 Release/Obj/OB1203.o:C:\Users.......OB1203.h:195: multiple definition of `osc_trim'; Output/blinky_pca10040_s132 Release/Obj/main.o:C:\Users............OB1203.h:195: first defined here

It seems like the file is located in multiple output files (both main.o and OB1203.o).

Hello Simon.

Do you mean my file (OB1203.h) is located in Obj folder, same folder of main.o and OB1203.o?

I checked, but that is not.

OB1203.c and OB1203.h is i created by my self, maybe it cause because i don't know how put file in right position.

Attach is picture locate of them.

Could you help me to take a look?

Hi Alex

How have you added the header file to your project? You should do this by right-clicking on the project ->Options -> Go to the preprocessor tab and add the path to the header file in "User include directories" Remember to set the project configurations to Common in the Options window. If you're having trouble with this I suggest checking out our SEGGER Embedded Studios - Getting Started videos.

Best regards,

Simon
