Eclipse中的Crypto ++未定义参考

问题描述

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):

I'm trying to use Crypto++ for my Eclipse C++ project using the MinGW toolchain. Problem is, whenever I try to use crypto functions, I get flooded with "undefined reference" errors. Has anyone experienced this before? This is the what I'm getting (truncated):

推荐答案

您的 -L 位于引号内.您是否尝试过:

your -L is inside of your quotes. Have you tried:

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

现在，g ++知道在哪里可以找到您的库了，您还需要从 C:\ Libraries \ crypto ++ 目录中指定要使用的库:

Now that g++ know where to look for your libs, you'll also need to specify which libs from the C:\Libraries\crypto++ directory you'd like to use:

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