/Fd (Program Database File Name)
Specifies a file name for the program database (PDB) file created by /Z7, /Zi, /ZI (Debug Information Format).
Without /Fd, the PDB file name defaults to VCx0.pdb, where x is the major version of Visual C++ in use.
If you specify a path name that does not include a file name (the path ends in backslash), the compiler creates a .pdb file named VCx0.pdb in the specified directory.
If you specify a file name that does not include an extension, the compiler uses .pdb as the extension.
This option also names the state (.idb) file used for minimal rebuild and incremental compilation.
To set this compiler option in the Visual Studio development environment
Open the project's Property Pages dialog box. For details, see Set C++ compiler and build properties in Visual Studio.
Click the C/C++ folder.
Click the Output Files property page.
Modify the Program Database File Name property.
To set this compiler option programmatically
This command line creates a .pdb file named PROG.pdb and an .idb file named PROG.idb:
CL /DDEBUG /Zi /FdPROG.PDB PROG.CPP
