Enabling the autobuild feature for non QNX C/C++ projects
By default, the IDE builds your project only when you tell it to, but it can also build your project automatically every time you change a file or other resource in any way (e.g. delete, copy, save, etc.). This feature is optimal when you have projects that are small in size, or not too many projects open at the same time. However, for best performance with very large projects, or if you have many open projects, you will want to leave the autobuild feature disabled.
To enable the autobuild feature:
From the main menu, select
In the left pane, expand General and select Workspace.
In the right pane, enable the Build automatically option.
Click OK to save and apply your preferences.
