Undefined reference to '----' in MCU xpresso

Hi,

    I am working on LPC54018 board. I have two different software stacks in MCU xpresso

 

1. One using a71ch with IBM watson platform

2.Second using LPC iot module with Alexa

 

Both projects are working successfully when I test them independently. I wanted to integrate them. I was able to do it almost but there is a place when I am not able to proceed further.

 

I have two files aws_shadow.h and its corresponding aws_shadow.c files. I need to call them in my main.c file in the function void prvShadowMainTask(void *pvParameters).

 

I made the code changes inside ibm_watsin_demo.c which holds the main() and when I try to navigate to SHADOW_Delete() function and other shadow functions, I am able to. But when I build my project , they are throwing me an error like below:

 

 

I have added the amazon-freertos folder which holds all the required files. But I am not able to map it in a right way. 

Is there any declaration or initialization function/file I am missing over here?

Any pointers would be helpful.

 

I have attached the project files with this.

 

Thank you

Thanks and Regards

Niranjan
