/DEBUGTYPE

Syntax:

/DEBUGTYPE:{CV|COFF|BOTH}

This option generates debugging information in one of three ways, Microsoft format (CV), COFF format, or both:

• /DEBUGTYPE:CV

  Visual Fortran requires new-style Microsoft Symbolic Debugging Information in order to read a program for debugging. To select this option in the Microsoft visual development environment, choose the Link tab of the Project Settings dialog box. In the Debug category, select the Microsoft Format button, which is only available if you have checked the Generate Debug Info box.

• /DEBUGTYPE:COFF

  This option generates COFF-style debugging information. Some debuggers require Common Object File Format (COFF) debugging information.

  When you set this option, the linker does not create a PDB; in addition, incremental linking is disabled.

  To select this option in the visual development environment, choose the Link tab of the Project Settings dialog box. In the Debug category, select the COFF Format button, which is only available if you have checked the Generate Debug Info box.

• /DEBUGTYPE:BOTH

  This option generates both COFF debugging information and old-style Microsoft debugging information.

  When you set this option, the linker does not create a PDB; in addition, incremental linking is disabled. The linker must call the CVPACK.EXE tool to process the old-style Microsoft debugging information. CVPACK must be in the same directory as LINK or in a directory in the PATH environment variable.

  In the visual development environment, specify this option with the Both Formats button, which is only available if you have selected Generate Debug Info.

If you do not specify /DEBUG, /DEBUGTYPE is ignored. If you specify /DEBUG but not /DEBUGTYPE, the default type is /DEBUGTYPE:CV.
