Eclipse中的Crypto ++未定义参考

Question

我正在尝试使用MinGW工具链将Crypto ++用于我的Eclipse C ++项目。 问题是，每当我尝试使用加密函数时，都会出现“未定义的引用”错误。 有谁之前经历过这个吗？ 这就是我得到的（被截断）：

您的-L在引号内。 你有没有尝试过：

g++ -L "C:\\Libraries\\crypto++" -lpthread -o "Grum Net.exe" "src\\VaultNode.o" "src\\User.o" "src\\Grum Net.o" 

既然g ++知道了在哪里寻找您的库，您还需要从C：\\ Libraries \\ crypto ++目录中指定您要使用的库：

g++ -L "C:\\Libraries\\crypto++" -lcryptolib1 -lcryptolib2 -lpthread -o "Grum Net.exe" "src\\VaultNode.o" "src\\User.o" "src\\Grum Net.o"
