There are two main ways of invoking a build in the C/C++ Perspective:
- From a project: by right-mouse clicking on the project and
selecting the Build menu option.

The invocation that is used to build a Project can be edited, by
opening the projects properties:


If the Automatic Build Feature is enabled,
then this invocation will be run every time a modified file is saved,
a file is deleted or created.
- From a makefile: After a file has been
designated as a makefile
you can right click on it, and choose menu option Build

This will cause a dialog to be shown where you can enter a build command:

On subsequent builds the same dialog will be shown with a history of past
command entries, so you can choose to rerun one of the previous commands
or edit any one of them and run the modified command, or enter a totally
new command.
