use to compile a D file and create an object file that is 
suitable for a Linux dynamic library (.so).

I believe it is probably

dmd -c -fPIC my_file.d

Also, what is the command line to create a dynamic library from 
one or more object files that have been compiled for dynamic 
invocation?

dmd ??? -shared ???

Thanks. I don't normally compile right into a .so, but I think 
this is OK:

dmd my_file.o my_other_file.o  -shared   -of=libutest.so


One thing I picked up from SCons is creating dynamic object files 
with a .os extension and static object files with the standard .o 
extension. That way they can be compiled in the same directory in 
the same build step. But dmd rejects the files that are named 
*.os. Is there an extension besides .o that dmd would accept for 
the dynamic object files?

I've been using .pic.o so it still ends with .o for dmd.

I was thinking that this might be a linker function only and 
tried to use g++ and gcc for the .so creation but, while they 
both create the same size file as each other, it is different 
than what dmd does when called with -shared.
