GCC Project Options and Configuration

Project options and configuration can be set up by either right clicking on the Solution Explorer → Project Properties, or by pressing Alt Enter .

This will call up the Project properties window, which has seven tabs.

If a tab supports properties that are configuration specific, then the tab has two slide-down menus. The Configuration field defines the project configurations to modify. By default, two configurations are provided in each project - Debug and Release. The Platform field is set to AVR. If a tab supports configuration independent properties, then the Configuration and Platform fields are disabled.
Note: Use the 'Save All (Ctrl Shift S)' from the File menu or toolbar to update the changes in the project file whenever changes are made.
