I use dmd package.d -verrors=3 -debug -I"../..".

I get

Error: undefined reference to `std.container.array.Array!(minimal.token.token.Token).Array.empty() const`
       referenced from `const bool std.container.array.Array!(minimal.token.token.Token).Array.opEquals(ref const(std.container.array.Array!(minimal.token.token.Token).Array))`

You need to include all modules on the command line that you import, or use the -i switch.

Oh, yes! I completely forgot about that.
Why isn't that the default behavior?!

You may be linking against it separately.

The -i behavior only works for small executables, when the build commands (yes plural) get more complex its not going to give you the control that you need.

I thought that's what the flag -I“...” was for. Provided the naming conforms to the standard.

-i uses the import path switches to source files from.

By default the D compiler defaults to looking in current working directory, hence why -i by itself works.
