使用混淆庫時vC++中的鏈接時間錯誤

我想在Windows上使用混淆庫。在vC++中編譯混淆時，會出現鏈接時間錯誤。如何解決它。請注意，libConfuse是一個配置文件解析器庫，用C寫的使用混淆庫時vC++中的鏈接時間錯誤

我已經加入libconfuse 2.6和提取它。我已經在它的src目錄中使用了lib，也是config.h。然後我從libconfuse主頁編譯了示例程序。

請解決此問題，請修改您的問題以更新它，而不是寫答案。 – 2009-10-26 11:42:07

我想你沒有添加一個引用到「confuselib」工作所需的庫。你可以檢查你的編譯器鏈接器包括，看看你是否添加了所有相關的混淆庫？

這些方法都在confuse.c中定義;要麼你沒有鏈接到混淆庫或其他版本，或者你用錯誤的配置構建了混淆庫。

現在問題已解決。當我從F：\ confuse-2.6 \ windows \ msvc6 \ libConfuse發送到F：\ confuse-2.6 \ windows \ msvs.net \ libConfuse \ Release
