Somehow the compiler doesn't link phobos.lib. Not sure why because the 
compiler dir is in my PATH and SC.INI is in the compiler directory, 
where the path to the lib is defined relatively...

to be honest with you, this is just a guess...
what about :
__gshared char[] x;

Ah, didn't saw this. I have a global static char[] but will try to use 
immutable and see if this helps.

Please let me know what you have figured out. have to deal with WIN API 
TlsAlloc stuff and I am a bit confused on how to bring D TLS and WIN TLS 
under one hood. Guess it's the Tls API indexing thing I can't get..
TIA

The thread local storage symbols will always creep in, because they are 
used by the phobos initialization.

IIRC the definition for the symbols is not in phobos, but in snn.lib, 
the C runtime library.

Are you following http://www.digitalmars.com/d/2.0/dll.html ?

The "DLL with a C Interface" works fine for me, but the "D code calling 
D code in DLLs" is rather old, if not broken. I've proposed

http://d.puremagic.com/issues/show_bug.cgi?id=4071

so all phobos objects and the GC can be shared between DLLs.

Yes, creating a DLL in D that has a C callinterface.


 The "DLL with a C Interface" works fine for me,


That's what I have used. But as posted I had to add the phobos.lib 
explicitly to the compile command.
