You can use either the /Zi or the /Z7 option with the /YX option to generate debugging information for CodeView or the integrated debugger.
It is recommended that you use the /Zi option unless you need /Z7 to maintain compatibility with Microsoft C/C++ version 7.0. The /Zi option places the generated debugging information into a program database (PDB); a PDB speeds linking during the debugging process. The /Yd option, which places all debugging information into every object file created using a precompiled header, is ignored unless used with /Z7.
The following table summarizes results obtained from using the /Zi, /Z7, and /Yd options in combination with /YX.
Results of Combining Debugging Options with /YX
| Option | Result |
| /Zi | Debugging information for both the precompiled header and the rest of the source code is placed in a program database (PDB) with the default name of MSVC.PDB. |
| /Zi /Yd | /Yd is ignored. Debugging information for both the precompiled header and the rest of the source code is placed in a PDB with the default name of MSVC.PDB. |
| /Z7 | Debugging information for both the precompiled header and the rest of the source code is placed in every object file created using the precompiled header. |
| /Z7 /Yd | Debugging information for both the precompiled header and the rest of the source code is placed in every object file created using the precompiled header. |
