Dear Expert,

I am using imx6 processor and wrote an application. To cross compile i am using yocto for that.


I have 4 files in different directory.


1. /home/Linux/NXP/XYZ/Embedded/read/read.c
2. /home/Linux/NXP/XYZ/Embedded/main/mainfun.c
3. /home/Linux/NXP/XYZ/Embedded/write/write.c
4. /home/Linux/NXP/XYZ/Embedded/config/config.c


and .bb file is located at




==> From mainfun.c i am calling different function which funcion defination are present inside write.c , config.c and 



==>I am only come across single file compilation using yocto so can you please help how i write .bb file , how can i compile and generate "XYZ_app" exicutable.


Here i attached .bb file which i have written but not working
