Is there dependency generation flag for MSVC like gcc's -M

Question

Is there dependency generation flag for MSVC like gcc\'s -M flag.

Every C++ compiler I have ever used had this kind of flag. How can I create dependencies a

Answer 1

You may be able to use:

/showIncludes show include file names

although you will probably also need some additional filtering afterwards to get the format that you need.

Answer 2

This batch script may be what you and I have been looking for, though I have not tested it.

Pass file as %1 and include path as %2

@ECHO %1: \
@FOR /F "tokens=1,2,3,*" %%A IN ('cl /nologo /c %1 /Zs /showIncludes /I%2') DO @IF NOT "%%D"=="" echo %%D \

Outputs:

filename.c: \
header.h \
someotherheader.h
