I know I'm supposed to use dub, but I'm not ready.

I just found out I can't use dmd switches for file names variable in a GNU makefile, e.g., see this fragment

%.o : %.d
      dmd -c $< -of $@

which doesn't work because the "-of" must be followed immediately by a file name with no intervening spaces.

This simple case works by simply removing the code chunk "-of $@" but the problem precludes more complex makefiles.

Also, I notice dmd has no simple way to output its version (by the way, I'm using dmd version 2.065 installed via the Debian apt package management system).

Am I missing something, or are these situations legitimate bugs?

Thanks.

Best regards,

        dmd -c $< -of$@

works for me with GNU Make 3.82.

You're correct, my error.  I had another error which I misinterpreted.
 So GNU make expands the "$@" variable even without the space after
"-of"--great!

Thanks for the help.

For the compiler version, I've submitted a PR:

Ok, the outcome is that a dedicated option is not seen as necessary. DMD already prints its version as the first line if you call it without arguments. If you need only the version, you can use:

    dmd | head -n1
