Hi,

I'm trying to write something very simple using D and sockets.
I'm creating a socket like this:
auto s = new TcpSocket;

But here I get a SocketException with message "Unable to create socket" and
code 10106

The application compiles just fine, I have linked with ws2_32.lib, but I get
this error.

The environment is Windows XP Home SP2 with D 1.010.

Regards,
Emil Ivanov

The error code from MSDN:

WSAEPROVIDERFAILEDINIT
10106 
Service provider failed to initialize. 
The requested service provider could not be loaded or initialized. This error
is returned if either a service provider's DLL could not be loaded (LoadLibrary
failed) or the provider's WSPStartup or NSPStartup function failed.  

(I got WSAEPROVIDERFAILEDINIT by looking in dm\include\win32\winsock2.h then I
searched MSDN online for the text)

Now, std.socket calls WSAStartup, not WSPStartup or NSPStartup so I suspect the
DLL is failing to load perhaps.  

The constructor for class Socket, called by TcpSocket calls the Win32 function
'socket' which on MSDN does not even mention the possibility of that error.

Try linking with wsock32.lib instead, and make sure you're linking with the one
in the dm\lib directory.
