什么是未定义的引用/未解决的外部符号错误，如何修复它?27日答案

I am programming since a few days and I simply want to open a window with opengl. I got glew and glfw, I linked the library of glew and the headers of both but when I compile I get an error. I've got windows7. I use def c++.

我从几天后就开始编程了，我只是想打开一个opengl的窗口。我得到了glew和glfw，我链接了glew的库和两者的头，但是当我编译时，我得到了一个错误。我有windows7多。我使用def c++。

This is the code:

这是代码:

#define GLEW_NO_GLU
#define GLFW_NO_GLU

#include <GL/glew.h>
#include <GLFW/glfw3.h>


int main() {
GLFWwindow* window1 = glfwCreateWindow(640, 480, "window1", NULL, NULL);
glfwMakeContextCurrent(window1);
return 0;
}

And this are the errors:

这是错误

C:\Users\Stefan\Desktop\Programmieren\Code\c++_Projekt2_OpenGL\main.o   In function `main':
C:\Users\Stefan\Desktop\Programmieren\Code\c++_Projekt2_OpenGL\main.cpp undefined reference to `glfwCreateWindow'

This is the compiler log or however it is called:

这是编译器日志，但它被称为:

From the log messages you posted, it seems that you haven't configured your Dev-C++ project properly to link against glfw:

从您发布的日志消息中，似乎您还没有正确地配置devc ++项目来链接glfw:

g++.exe -D__DEBUG__ main.o -o Projekt2.exe -L"C:/Program Files (x86)/Dev-Cpp/MinGW64/lib32" -L"C:/Program Files (x86)/Dev-Cpp/MinGW64/x86_64-w64-mingw32/lib32" -static-libgcc glew-1.10.0/lib/Release/Win32/glew32.lib -m32 -g3

The glfw library is missing, that is why you're getting an undefined reference to its functions. You should set up it as you did with glew32.

glfw库丢失了，这就是为什么您对它的函数有一个未定义的引用。你应该像对待glew32那样建立它。

Also, the link to What is an undefined reference/unresolved external symbol error and how do I fix it?, provided in the comments to your question, is worth the read.

另外，链接到未定义的引用/未解决的外部符号错误，以及如何修复它?在对你的问题的评论中提供的，是值得一读的。
