2. Reference the Nios II C/C++ library project from your Nios II C/C++ application

project. This step ensures that your Nios II C/C++ library project builds before

your Nios II C/C++ application project. It also ensures you can easily step into the

C/C++ library code when debugging your application project.

a. Click Project References in the left-hand pane.

b. Turn on the Nios II C/C++ library project you want to reference.

3. Set up the linker options so your Nios II C/C++ application project can locate your

library. The C/C++ library is not automatically detected when you reference the

project; you have to explicitly add it.

a. Click C/C++ Build in the left-hand pane.

b. Click the Tool Settings tab.

c. Expand Linker. The General option appears.

d. Click General. The Libraries and Library Paths panes appear.

e. In the Libraries pane, click

Add Library and type the name of the

Nios II C/C++ library project. Do not press the Browse... button.

f. In the Library Paths pane, click

Add Library Path and add the path

to the *.a library file. The library path should include the Debug or

Release folder. Note that you will have to update the library path if you

change the configuration (i.e. Release or Debug) of the Nios II C/C++

library project.

4. Set up the include paths to locate headers from your Nios II C/C++ library project.

If your Nios II C/C++ library project includes header files you would like to access

from your Nios II C/C++ application project, you need to specifically enter the

paths to the header files.

a. On the Tool Settings tab, expand Nios II Compiler. The General

option appears.

b. Click General. The Include Paths pane appears.

c. In the Include Paths pane, click

Add Include Path and add the full

or relative path to the folder containing the header files.

5. Click OK to close the Properties dialog box.
