Formatting the Output of a Custom Build Step or Build Event

If the output of a custom build step or build event is formatted correctly, users get the following benefits:

  • Warnings and errors are counted in the Output window.

  • Output appears in the Task List window.

  • Clicking on the output in the Output window displays the appropriate topic.

  • F1 operations are enabled in the Task List window or Output window.

The format of the output should be:

{filename(line# [, column#]) | toolname} : [ any text ] {error | warning} code+number:localizable string [ any text ]


  • {a | b} is a choice of either a or b.

  • [item] is an optional string or parameter.

  • Bold represents a literal.

For example:

C:\sourcefile.cpp(134) : error C2143: syntax error : missing ';' before '}'

LINK : fatal error LNK1104: cannot open file 'somelib.lib'
