I don't understand how to use the new -deps command line argument of DMD1/2.
To test it I have created three little modules:

// main.d
import mod1: foo;
void main() {
    printf("%d\n", foo(10));
}


// mod1.d
import mod2: bar;
int foo(int x) { return bar(x) + bar(x); }


// mod2.d
int bar(int x) { return x * x; }

I can compile them normally with:
dmd main.d mod1.d mod2.d

Then I try to use -deps, I use:
dmd -o- -deps=deps.txt main.d mod1.d mod2.d

But the 'deps.txt' file is empty. Can you tell me what's wrong?

Bye and thank you,
bearophile

The changelog of D1 and D2 says that both have -deps, and indeed both compilers
accept such flag, but DMD1 doesn't seem to work with it. While I've just seen
DMD2 produces an output file. Is this a D1 bug?

I get exactly the same thing. Running with D1 gives an empty file and
running with D2 gives a file with content. I'd say it looks like a bug, so
bugzilla, here I come :-)
