i我在dev c ++编译器上编译这个程序但是我遇到错误

请求帮助我在Dev C ++上运行这个程序

i am compile this program on dev c++ compiler but i face error
plese help me to run this program on Dev C++

推荐答案

代码片段用于Visual C ++，但你使用的是Dev C ++。



第一行

The code snippet is for Visual C++ but you are using Dev C++.

The first line

#pragma comment (lib,"cryptlib.lib")

是Microsoft特定并将应用程序与指定的库链接。您必须使用适合您的开发环境的步骤将您的应用程序与该库链接。



但是，您必须确保拥有与您的开发兼容的库版本环境。如有必要，您必须使用Dev C ++构建库。

is Microsoft specific and links the application with the specified library. You must use the appropiate steps for your development environment to link your application with that library.

However, you must ensure to have a library version that is compatible with your development environment. If necessary you must build the library using your Dev C++.

使用dev cpp 5.6.3编译器并添加libcryptopp.a文件以在项目中删除第一行

using dev cpp 5.6.3 compiler and add libcryptopp.a file to project and delete first line in code
