Configuring Project Dependencies
Projects in the Nios II IDE can be dependent on other Nios II IDE projects. Nios II C/C++
application projects inherently depend on a single Nios II system library project. Nios II
C/C++ application projects and Nios II user-makefile C/C++ application projects can also
depend on Nios II C/C++ library projects. Nios II C/C++ library projects can depend on other
Nios II C/C++ library projects. During the build process
for a project, the Nios II IDE first
builds all dependent projects.
The Nios II IDE automatically establishes a dependency between the Nios II C/C++ application
project and the Nios II system library project at the time you create the Nios II C/C++
application project. You do not and should not create project dependencies between Nios II
C/C++ application projects and Nios II system library projects manually. The Associated
System Library page of the Properties dialog box for your Nios II C/C++ application project
contains details about this special dependency. Once the dependency exists, you can change it
to reference a different Nios II system library project.
Nios II library projects are the most common project dependencies. Making an application
project dependent on a Nios II library project allows you to do the following:
Ensure your Nios II C/C++ library builds and is up to date when you compile your
application project.
Call functions in the Nios II C/C++ library from your application project.
Include header files located in a Nios II C/C++ library.
Debug and step into source code located in the Nios II C/C++ library.
Note: After adding a project dependency, you must also edit the application makefile to
refer to the project depended upon.
To change dependence on a Nios II system library project:
You must edit the application makefile to change the project build behavior. Then, carry
out the following steps:
1. Right-click your Nios II C/C++ application project in the Nios II C/C++ Projects
view, and then click Properties. The Properties dialog box appears.
2. Click Associated System Library in the left-hand pane.
3. Click Browse.... A list of Nios II system library projects appears.
4. Select a Nios II system library project.
5. Click OK to close the list of Nios II system library projects.
6. Click OK to close the Properties dialog box.
