2) Will dmd support exporting/importing data symbols from dlls? I know
there is a patch that does the data symbol address patching from the
runtime but thats a feature that should be supported by the compiler
directly in my eyes.
Importing data symbols works just fine both in DMD and GDC. At least it
did a couple of years ago. Can't remember if I've tried exporting, but I
wouldn't be surprised if it worked.
You don't need to do anything special to get it working, just use
declare the data as 'export extern extern (C)' in your D code. For D2
prefix that with '__gshared'. Not very elegent, but it does work.
I tried that but it does not work. For example compiler generatd data
symbols like the module info or the vtable don't get exported even if
the class is declared as "export" Also the tls storage does not work
with threads across dll boundaries. And a lot of other stuff. I consider
dll support working as soon as phobos is a shared dll.
I see. I assumed you were talking about linking with DLLs written in C.
I've never tried linking with a D DLL, except for maybe a simple test
case.
