I'm looking something similar to -M flag of gcc which returns all
header files which are included in compiled file.
This list can be used later in makefile as dependency.
m4 have also "include" directive which resembles C #include. Is
there're something similar to "gcc -M" for m4?
to the extent that they need a tool for dependencies.
Have you looked at turning on the m4 trace and parsing that?
You could modify m4 or get a copy of makedepend and modify
it to handle m4.
There's an option to invoke m4 in debug mode. In the mode all included
files are printed. So it indeed possible to filter out from it all
I just thought that there's a better way and not to invent the wheel
get that to work, especially if you could turn off further passes in the
compiler. Maybe running cpp alone would be enough, but I never tried
anything like this.
