Looks like a good enhancement for rdmd. That it doesn't "fail 
successfully" is a bug.

 spir: rdmd's command-line syntax is like this:

rdmd {args to dmd and rdmd} app.d {args sent to app.exe}

So anything after the first *.d param is automatically considered a param 
for when rdmd runs the app your building, not for rdmd/dmd. Of course, if 
you're using --build-only, then such params just simply get ignored. In 
short, you have to do it like this:

rdmd --build-only -ofmyProg myCFuncs.o myProg.d

Unfortunately, that still doesn't work with the official version of rdmd. 
However...

 Andrei: I submitted an rdmd patch for this not too long ago:

http://d.puremagic.com/issues/show_bug.cgi?id=4928

It fixes this problem for object files, static library files, ".def" files 
and response files.

May I suggest that rmdm prints out the command it sends to dmd (even when s=
uccessful)? Not only it's "educative" but it should provide the correct lis=
t of modules ;-) (so that solving the issue about C files is then 3s work).

Right, than you. Anyway finishing with the "program" module (the only only =
one that should have a main()) makes sense. And if it's for running its arg=
s come next.
But the: how would rdmd makes the distinction when a prog happens to apply =
on modules? (You know, refactoring tools or such). My choice would be that =
they must first be 'built-only'.


 Unfortunately, that still doesn't work with the official version of rdmd.=

The --chatty option should help.

All that I have access to. Which is two: WinXP and Kubuntu (both x86, 
32-bit).

I have some other rdmd patches in bugzilla too. A bugzilla search on "rdmd" 
will find them all.
