The only time pragma(lib) works is when the file it's in is provided on the command line. rdmd can work around this as it invokes dmd twice, there's not a lot that can be done otherwise though.

You mean it doesn't work for .di files, I'm aware of that.

dmd -c a.d
dmd -c b.d
dmd a.d b.d

...

Cue linker errors if A or B has a pragma(lib) in it and relevant extern declarations.

Did you mean that last line to be "dmd a.obj b.obj"?
