multiple makefiles in one directory

Question

I have a makefile in a directory of mine which builds scripts with certain environment variables set. What if I want to create another makefile in the same directory with different environment variables set? How should I name the two make files? Does makefile.1 and makefile.2 work? How do I call them?

Answer 1

You can give sensible names to the files like makefile.win and makefile.nix and use them:

make -f makefile.win
make -f makefile.nix

or have a Makefile that contains:

win:
  make -f makefile.win

nix:
  make -f makefile.nix

and use make win or make nix
