digitalmars.D.ldc - LDC Dll support

reply Benjamin Thaut <code benjamin-thaut.de> writes:
How far is the dll support of LDC?
Does the -shared option of the compiler actually work for the x86 mingw 
or x64 msvc versions of ldc?
If it does work, what does -shared do? Does it always export all symbols 
or only those annoted with the "export" attribute?

Kind Regards

Hi Benjamin,

I never tried to build a dll with x86 mingw compiler - I have to 
check this. The x64 msvc compiler is currently not able to build 
a dll - some support code is still missing.

Regards,
Kai

That is unfortunate. Then I will have no choice to implemented propper 
DLL support in the reference compiler ;-)

In case you ever try to get it working within ldc I strongly recommend 
that you ignore the "export" protection level, as it is horribly broken 
in may ways (see http://wiki.dlang.org/DIP45). Or wait until I'm done 
implementing DIP45 and its actually accepted into the master branch of dmd.

Kind Regards

What you refer to is probably only an organizational issue for 
libraries, which are to be built as both static and dynamic, it 
doesn't apply to code, which is only to be built as dynamic.
