我正在試驗Windows的WinPcap 4.1.1庫,但我無法設法編譯甚至是庫提供的示例源文件。Winpcap MinGW編譯錯誤
我得到這些錯誤:
'PCAP_OPENFLAG_PROMISCUOUS' 未申報(在一次使用此功能)
'PCAP_SRC_IF_STRING' 未聲明(在一次使用此功能)
而且一堆警告:
隱式函數聲明'localtime_s'
i功能mplicit聲明「pcap_findalldevs_ex」
的功能「pcap_open」
的功能隱式聲明隱式聲明「scanf_s」
我用Google搜索了一下,發現我應該添加一行#define HAVE_REMOTE
(我沒有線索它做什麼),但它在更多的錯誤會導致這樣的:
未定義的引用「pcap_open」
未定義的引用「pcap_findalldevs_ex」
取消定義d引用'localtime_s'
"pcap.h"
似乎被正確包含(eclipse不報告任何包括錯誤)。 我已將* .lib文件複製到MinGW/lib direcotry中,並在Path and Symbols->Library Paths
(eclipse項目屬性)中設置此路徑
我不知道接下來要嘗試什麼。任何想法都歡迎。 在此先感謝
下面的代碼:

「未定義的引用」消息意味着你沒有與'libpcap'鏈接。 'pcap-config --libs'會給你鏈接所需的標誌。 http://developer.apple.com/mac/library/DOCUMENTATION/Darwin/Reference/ManPages/man1/pcap-config.1.html – 2010-02-18 09:33:49
@Alok我認爲你是對的我只是設置庫目錄,而不是鏈接庫。鏈接'wpcap.lib'和'Packet.lib'後,我得到'localtime_s'和'scanf_s'函數只有2個未定義的引用錯誤。這些功能在哪裏? – 2010-02-18 09:57:02
