Severity levels

Reference Guide

A diagnostic that is produced when the compiler has found a construct which clearly 
violates the C or C++ language rules, such that code cannot be produced. An error will 
produce a non-zero exit code.

A diagnostic that is produced when the compiler has found a condition that not only 
prevents code generation, but which makes further processing of the source code 
pointless. After the diagnostic has been issued, compilation terminates. A fatal error will 
produce a non-zero exit code.

The diagnostic can be suppressed or the severity level can be changed for all diagnostics, 
except for fatal errors and some of the regular errors. 

See Options summary, page 169, for a description of the compiler options that are 
available for setting severity levels.

See the chapter Pragma directives, for a description of the pragma directives that are 
available for setting severity levels.

An internal error is a diagnostic message that signals that there has been a serious and 
unexpected failure due to a fault in the compiler. It is produced using the following form:

Internal error: message

where 

 is an explanatory message. If internal errors occur, they should be 

reported to your software distributor or IAR Technical Support. Include information 
enough to reproduce the problem, typically: 

●

The product name

●

The version number of the compiler, which can be seen in the header of the list files 
generated by the compiler

●

Your license number

●

The exact internal error message text

●

The source file of the program that generated the internal error

●

A list of the options that were used when the internal error occurred.
