Using user libraries (.a file) for NIOS application project

Dear friends,

I have 2 projects:

• The first one: NIOS II library (c header files).

• The second one: NIOS II Aplication and BSP from Template.

I want to refer the library project from the application project, the application project could be included C header files in the library.

example: the library has abc.h file and the the application project could be included abc.h to use define on it.

I added the project references in the application project properties. But it don't work.

Please tell me how to do that!
