## 9 Compilation/Build

This chapter describes how to compile files, build executables and run them. Most capabilities can be accessed through the `Build` menu item, or through the `Build` and `Run` contextual menu items, as described in the following section.

When compiler messages are detected by GPS, an entry is added in the Locations View, allowing you to easily navigate through the compiler messages (see The Locations View), or even to automatically correct some errors or warnings (see Code Fixing).

Compiler messages also appear as icons on the side of lines in the source editors. When the mouse pointer is left on these icons, a tooltip appears, listing the error messages found on this line. When GPS is capable of automatically correcting the errors, clicking on the icon will apply the fix to the source code. The icons on the side of editors are removed when the corresponding entries are removed from The Locations View.
