/PDBALTPATH (Use Alternate PDB Path)
For the latest documentation on Visual Studio 2017 RC, see Visual Studio 2017 RC Documentation.
The path and file name for the .pdb file.
Use this option to provide an alternate location for the Program Database (.pdb) file in a compiled binary file. Normally, the linker records the location of the .pdb file in the binaries that it produces. You can use this option to provide a different path and file name for the .pdb file. The information provided with /PDBALTPATH does not change the location or name of the actual .pdb file; it changes the information that the linker writes in the binary file. This enables you to provide a path that is independent of the file structure of the build computer. Two common uses for this option are to provide a network path or a file that has no path information.
The value of pdb_file_name can be an arbitrary string, an environment variable, or %_PDB%. The linker will expand an environment variable, such as %SystemRoot%, to its value. The linker defines the environment variables %_PDB% and %_EXT%. %_PDB% expands to the file name of the actual .pdb file without any path information and %_EXT% is the extension of the generated executable.
