The C/C++ compiler generates errors when it cannot translate your code because of improper syntax. Errors are fatal; the compiler cannot generate object code because of improper syntax.

For descriptions of the CodeWarrior C/C++ compiler's errors, see the CodeWarrior Error Reference.

The compiler can also optionally generate helpful warnings that alert you to source code that is syntactically correct but might be logically incorrect or ambiguous. These mistakes are legal C and C++ source code, but the code might not do what you expect.

When the compiler finds one of these possible mistakes, it can generate a warning. Warnings are not fatal. Unless you choose to treat these warnings as errors, your source code will still compile (although it may not run as you intended it to).

This section describes these warnings. The topics in this section are:

• Treating All Warnings as Errors
• Catching Illegal Pragmas
• Catching Empty Declarations
• Avoid Unintentional Errors
• Finding Unused Variables
• Finding Unused Arguments
• Catching Empty Declarations
