I appear to be unable to use Google the last couple of days :-( so I admit defeat, expose my current ignorance, hopefully to quickly become enlightened.

Is it possible to easily with DMD, LDC and/or GDC create shared objects aka dynamic libraries from a D code base?

Currently for me DMD and LDC refuse to accept the existence of a -shared flag, and GDC always fails with some deeply incomprehensible messages about not finding _tls.* functions.

There should be a page better than  http://dlang.org/dll-linux.html

Yes, support is relatively solid for DMD/Linux : http://forum.dlang.org/post/minijortxmmyshyfniby@forum.dlang.org

Don't use Windows but it is said to be much more complicated there. For LDC/GDC support is not yet ready AFAIK.

Hummm…. it seems that DMD still tries to search libphobos2.a by default instead of libphobos2.so, so the -defaultlib=libphobos2.so is the difference between success and failure :-(

I'll have to get my wife's Windows 7 machine out to test all the D tool changes I am making. It is a real shame that anyone actually uses Windows for anything :-)

As far as I understand shared one will become default only full stack of D utilities for working with loaded libraries will be available in runtime (right now you need to resort to dlsym) and tested a bit. Right now it is kind of semi-official.

DMD works quite well with Wine, what I've heard. But that might not be reliable enough.

It's linux users, who use linux. Windows users don't use windows for anything, they use software running on windows, lol.

It awesome how this statement can be read as both linux flaw and merit depending on who reads it :)

I'm making a game engine using shared objects as scripts, take a look at https://github.com/ICGCC/Breaker-Engine

You should also check out my fork, which is a little more recent.

Point in case, look at src/breaker/util/core.d and you'll see what you need to do.

Oh, than and shared objects only REALLY work with DMD and linux atm, windows is dodgy, and I've tested it.
