之前在C++Builder 運行沒問題，后來不知不覺就報錯，然后我重裝了下c++builder 之前也安裝了Indy10,但現在報錯，請大家幫我看下到底是哪出現問題了.我在工程里參考了ws2_32.lib,directores/conditionals別管理includepath 還是libraypath都已經把vcl和Indy10的目錄全都加進來了，但還是報錯,我看網上說是重定義但我應該是已經定義完了，因為以前運行沒有問題的,代碼一是套代碼沒做任何改動過。謝謝大家

嘗試調整頭檔案的包含順序。uj5u.com熱心網友回復：
可是確實以前編譯運行沒問題，代碼我都沒動過，而且我也試過調式順序，沒用uj5u.com熱心網友回復：
有些多次定義，洗掉一些多余的頭檔案uj5u.com熱心網友回復：
刪什么檔案呢uj5u.com熱心網友回復：
把winsock2.h 的頭檔案注釋掉試試uj5u.com熱心網友回復：
把#include <winsock2.h>這句放到最前面uj5u.com熱心網友回復：
這個說不好你試試樓上大俠的辦法
不行的話 再一步步來吧
uj5u.com熱心網友回復：
重定義了結構，結構在多個頭檔案中同時使用定義，你可以改變一下頭檔案的次序，winsock2.h放在windows.h的前面uj5u.com熱心網友回復：
重新梳理一遍就好了。轉載請註明出處，本文鏈接：https://www.uj5u.com/houduan/137566.html
