digitalmars.D.learn - Shared objects aka dynamic libraries

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

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.
