Windows套接字asm：上下文堆棧爲空

Question

您好，我在編譯NASM代碼時遇到了結構問題。

這是我的結構定義和聲明：

struc wsa_data_struct 
    .wVersion resw 1 
    .wHighVersion resw 1 
    .szDescription resb WSADESCRIPTION_LEN 
    .szSystemStatus resb WSASYS_STATUS_LEN 
    .iMaxSckets resw 1 
    .ImaxUdpDg resw 1 
    .lpVendorInfo resb 1 
    .size 
endstruc 

wsa_dat: 
    istruc 
     at wsa_data_struct.wVersion, dw 0 
     at wsa_data_struct.wHighVersion, dw 0 
     at wsa_data_struct.szDescription, db 0 
     at wsa_data_struct.szSystemStatus, db 0 
     at wsa_data_struct.iMaxSckets, dw 0 
     at wsa_data_struct.ImaxUdpDg, dw 0 
     at wsa_data_struct.lpVendorInfo, db 0 
    iend 

，當我嘗試編譯我的代碼，這個錯誤彈出：

error: (at:1) `%$strucname': context stack is empty 
error: (at:1) `%$strucstart': context stack is empty 
error: (at:1) `%$strucname': context stack is empty 
error: (at:1) `%$strucstart': context stack is empty 
error: (at:1) `%$strucname': context stack is empty 
error: (at:1) `%$strucstart': context stack is empty 
. 
. 
. 

這只是strucuture的聲明，它的第一線繼續爲每一行

istruc需要結構的名稱：

istruc wsa_data_struct 

參見：http://www.nasm.us/doc/nasmdoc4.html#section-4.12.11

BTW：.size需要一個像類型resd 1。
