Question

所以我仍然试图让我的破解graphics.h lib工作。我非常接近修复所有奇怪的错误。我已正确安装了一切。我对未定义的错误有很多麻烦：

我该怎么办？谷歌不会帮助我。如果您还有其他需要，请告诉我，我会提供：D

我的代码：

#include <iostream>
#include <graphics.h>
using namespace std;

int main()
{
    cout << "Hello world!" << endl;
    initwindow(1000,1000);
    return 0;

}

Answer 1

您似乎没有链接到gdi32库，但是您要包含标题。

编辑：我不知道Codeblocks是如何工作的。您的教练是否强迫您使用该编译器，因为您可以在https://www.visualstudio.com/downloads/download-visual-studio-vs免费下载和使用Microsoft Visual Studio 2015，它是一个更好的编译器，并在您的调试信息中提供更多详细信息。除了无法访问您的控制台程序设置和非常稀疏的调试信息之外，我唯一可以说的是确认您在入口点源文件中包含Windows.h并且如果您不限制使用哪个编译器去VS 2015它是使用c ++ V14的最新Visual Studio，将更加用户友好祝你好运..

Answer 2

实际上你的程序适用于windows gui 32.你应该选择windows gui 32模板而不是控制台应用程序。

对函数的未定义引用甚至不使用？
