I'm not quite sure why you're trying to use rdmd to build shared 
object files... rdmd is designed to run programs, not to build 
libraries. That's why it won't put a .so extension, it just 
(AFAIK) isn't designed for shared libraries. So why are you 
trying to use it instead of dmd?

Besides, extensive glob (the "./**/*" thing) is shell dependant, 
I'm not sure it is possible on bash, it may be zsh-only. You 
could however do (assuming you're on an UNIX system) “ find . 
-name "*.d" | xargs dmd <your_options> ” where “find” finds .d 
files and xargs passes them as argument to dmd.
