flat assembler - Win Sockets - undefined symbol?

Hi all,

I've been trying to get into FASM recently but am currently stuck on "undefined symbol WSAStartup" among the various other pitfalls.

Code:

format PE64 console
entry start


                ;Include list,
                include 'D:\fasm\include\win64w.inc'
                include 'D:\fasm\include\equates\WSOCK32.inc'
                include 'D:\fasm\include\api\WSOCK32.inc'
                include 'D:\fasm\include\pcount\WSOCK32.inc'
                include 'D:\fasm\include\api\user32.inc'
                ;Code section,



                section '.code' code readable executable

                start:

                invoke  WSAStartup, word 0x0202, qword [Socket_WSADATA]

                ;should test if zero, otherwise error
                invoke socket, AF_INET, SOCK_STREAM, IPPROTO_TCP
                mov [Socket_ID], rax


                invoke  getaddrinfoW, , [Login_server], ,[Socket_ppResult]
                mov ebx, [Socket_ppResult]
                mov ebx, [ebx+32]
                mov [Socket_sockaddr_in.sin_addr], ebx
                invoke freeaddrinfow, socket_ppResult

                invoke  connect, Socket_ID, [Socket_sock_addr], 16



                section '.data'

                Login_Server db "http://", 0

                section '.bss' data readable writeable

                Socket_ID                rq                  1
                Socket_WSADATA           WSADATA             ?
                Socket_sockaddr_in       sockaddr_in           AF_INET, 3308,
                Sock_ppResult            rq                  1
                PVP_server_IP            rd                  1

So, I am not too sure what I am supposed to be doing to make that invoke valid? (I'm sure there will be more errors to follow too) - I've had to add size references in like "word 0x0202" and tweak stuff around just to get rid of errors :S, I'm not even sure if anything in there is correct now :/

The various includes which come with Fasm is nice, but now it means I have no clue why WSAStartup is throwing an error as I can see it in the includes... plus, I had to define an extra structure with one of the fields being size_t which has no real conclusive size other than "it varies to the highest values needed".. or something a long those lines so "WSADATA" could have the wrong size slapped in the middle of it...

Any help appreciated.
