When trying to compile on Mac, although it compiles fine, I get the following error when trying to run it (it seems that it gets run at the end of compilation; a binary is produced that when run gives the same output as the line starting with "dyld" onwards).
Namidas-Mac-mini:lix namida$ dub -b release
Performing "release" build using dmd for x86_64.

Some Googling suggests this is due to special requirements regarding event handlers on OSX, so Allegro basically makes itself the main thread and runs the user code in a sub-thread. This is known to fail on main functions that don't have a very specific set of arguments - however, D does not seem to allow changing them to the "correct" ones (and this would probably break other code anyway).
One other solution suggested is to link Allegro to the binary statically rather than dynamically. I have yet to figure out how to do this, but it does seem to involve compiling Allegro myself - which in turn will not properly compile against Mac OSX 10.13 system libraries. (As such, my current task is to figure out how to compile it against older system libraries, without resorting to actually installing an older version of OSX on my system.)
One last suggestion I've seen is not to strip the labels from the executable. I'm not deliberately doing that, and would have no idea how to explicitly tell dub / DMD not to do so (I did try googling this, but the few relevant responses I could find seem to imply D doesn't do this automatically).
