My component source list includes:

    easyrtd.src/COMRtdInterface.cpp
    easyrtd.src/EasyRTD.rc
    easyrtd.src/EasyRTD.idl

and after fixing up the paths Visual Studio builds the project OK.

However, nmake does not - the RC compiler runs before MIDL.

It seems that there is a dependency that's missing. This would seem to be the implied one from the TYPELIB statement in the RC file.

Is it enough to use OBJECT_DEPENDS on the rc file (treating the implied res file as an object) naming the tlb that would be output by midl?

Presumably I'd also have to declare that the idl file produces the tlb file, using OBJECT_OUTPUTS? (Or not? This is only for Makefile generators, but how is the OBJECT_DEPENDS going to be handled in other cases?)

There seems to be an element of magic going on here rather than explicitly handling the midl/rc/link toolchain. I know Visual Studio tries to make this stff easy - but how does it work with nmake (and ideally the mingw toolchain too)?
