PRB: PRF1621 Error from Profiler for Windows NT (100774)



The information in this article applies to:

  • Microsoft Source Profiler 1.0

This article was previously published under Q100774
The information in this article is included in the documentation starting with Visual C++ 5.0. Look there for future revisions.

SYMPTOMS

An attempt to profile an application using the line count and line cover options fails and the Profiler generates the following message:
PREP: fatal error PRF1621: no debugging information in file 'filename'

CAUSE

This error occurs when the application being profiled contains debugging information in COFF format.

RESOLUTION

Profiler requires debugging information in CodeView format. Either change the debug options to /DEBUGTYPE:cv to generate CodeView format or to /DEBUGTYPE:both to generate both COFF and CodeView format debugging information.

MORE INFORMATION

This error occurs only when you specify the line count or line coverage options in Profiler. This functionality sets breakpoints in the code using debugging information in CodeView format. This should not be an issue for the function count or function coverage options.
