Building the Project

Building a project in the Nios II IDE compiles and links all the source code associated with the

project and the system library project. The result of building is an executable file (.elf) that

you can run or debug.

Use the following methods to build the project:

Right-click on the project in the Nios II C/C++ Projects view, and click Build Project.

Note: Make sure you build the application project tutorial, not the system library

tutorial_syslib. Building the system library does not create an executable file.

When building a project, the Nios II IDE first builds all other projects that the current project

references. Therefore, the system library project is usually built first. Building a project the

first time might take a few minutes while the Nios II IDE builds the system library.

Subsequent builds are faster.

In the IDE workbench, the Console view displays messages generated by the GCC tool-chain

during compilation. The Problems view displays any warnings or errors. (In this example,

there are no errors.)

Note: If building the project generates warnings or errors, the Problems view appears

automatically. You can double-click each row to jump to the line of code that caused the

warning/error.

Note: The information displayed in the Console and Problems views depends on the

project selected in the Nios II C/C++ Projects view. If you accidentally select a different

project, you will see unexpected (or no) text in the Console and Problems views.

After successfully building the project, you can download and run the application on your

development board. Refer to Running the Project

for instructions. To debug your application

on the board, refer to Debugging the Project
