DMD will generate one object file per module file, unless you
use the -of
option.
This is incorrect. It'll generate one object file per
invocation of dmd.
Erm, that's not quite correct either. I meant, one object file
per module file passed on the command line.
I tried this
dmd test.d test2.d
Got one test.o and one binary test. No test2.o. Must be that
thing where all modules compiled are smashed. The first filename
dictates the .o name. Correct?
Also tried
dmd -c test.d test2.d
In that case yes both .o are generated.
So the trick with all this is how to opt between building all and
building each incrementally. Any tools helping with that? For
example tool that shows dependencies. If some files are dependent
on each other they better be compiled together anyway.
