It's saying those files are not in the project directory. Did you download them?

got download them but still error

 

Are they in the project directory?
when you use inverted comma's in the include statement, it means they are located locally.
ie
#include "dac_dac8311.h" they must be in the project directory or the linker wont be able to find them.

 

got still error

 

You need to put it in the PHYSICAL directory.. Just because it shows in the build tree doesn't mean its in the right place.

[/Q
what mean by physical directory ? the c file is inside the folder

 

The error is " Which doesn't exist in the disk" Ergo the file ISN'T in the build directory.

The linker cannot find those three files.. Your program has included them, but cannot find them.

 

The yellow triangle states the file is missing..
