Use /Zi to Compile Commands Invoked with "?" Command

ID: Q43556

The information in this article applies to:

Microsoft CodeView for MS-DOS, versions 3.0, 3.11, 3.14, 4.0, 4.01, 4.05, 4.1
Microsoft CodeView for OS/2, versions 3.0, 3.11, 3.12, 3.5
Microsoft CodeView for Windows, versions 3.0, 3.05, 3.06, 3.07, 4.0, 4.01, 4.1
Microsoft CodeView for Win32s, version 4.25

Invoking C functions in CodeView using the "?" command works as expected as long as the function is contained in a module that was compiled with /Zi for the CodeView information. However, an attempt to directly call a function in the C run-time library or in the Windows application programming interface (API), CodeView returns the error message "syntax error" or "symbol 'xxxx' not found."

The reason for the error message is that the module containing the library function is not compiled with the CodeView option /Zi. The error message does not depend on the fact that the function is in the library and not in your application. If you use the "?" command to attempt to call a user-defined function in a module that is compiled without including CodeView information, CodeView returns the same error message.

The "?" command is formally referred to in the CodeView Utilities menu as the Display Expression command.
