ada-mode: Compiler errors

 
 4.2 Compiler errors
 ===================
 
 The ‘Check file’, ‘Compile file’, and ‘Build’ commands all place
 compilation errors in a separate buffer named ‘*compilation*’.
 
    Each line in this buffer will become active: you can simply click on
 it with the middle button of the mouse, or move point to it and press
 <RET>.  Emacs will then display the relevant source file and put point
 on the line and column where the error was found.
 
    You can also press the ‘C-x `’ key (‘next-error’), and Emacs will
 jump to the first error.  If you press that key again, it will move you
 to the second error, and so on.
 
    Some error messages might also include references to other files.
 These references are also clickable in the same way, or put point after
 the line number and press <RET>.
