g++这个报错是怎么回事？如何解决？（涉及OpenGL)

[Leon C.]

我用“g++ the_tank_war.cpp -o the_tank_war -lglfw3 -lGL -lX11 -lpthread -lXrandr -lXi”命令编译使用了glfw的c++代码时出现了下面的报错提示：

/usr/local/lib/libglfw3.a(x11_init.c.o): In function `initExtensions':
x11_init.c:(.text+0x1b05): undefined reference to `XineramaQueryExtension'

x11_monitor.c:(.text+0x682): undefined reference to `XineramaQueryScreens'
collect2: ld returned 1 exit status

代码如下：

#include<iostream>
#include<GLFW/glfw3.h>
using namespace std;

void framebuffer_size_callback(GLFWwindow* window, int width, int height);


int main()
{
	glfwInit();
	glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
	glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
	glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
	
	GLFWwindow* window = glfwCreateWindow(800, 600, "fly's window", NULL, NULL);
	if(window == NULL)
	{
		cout << "Failed to create GLFW window" << endl;
		glfwTerminate();
		return -1;
	}
	
	glfwMakeContextCurrent(window);
	
	glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);
	
	while(!glfwWindowShouldClose(window))
	{
		glfwSwapBuffer(window);
		glfwPollEvents();
	}
	
	glfwTerminate();
	return 0;
}


void framebuffer_size_callback(GLFWwindow* window, int width, int height)
{
    glViewport(0, 0, width, height);
}

把lGl和lglfw3交换一下顺序

还是不行....

新增了这两个报错：

/tmp/cco8XNYv.o: In function `main':
test2.cpp:(.text+0xdd): undefined reference to `gladLoadGLLoader'
/tmp/cco8XNYv.o: In function `framebuffer_size_callback(GLFWwindow*, int, int)':
test2.cpp:(.text+0x192): undefined reference to `glad_glViewport'

undefined reference to 是未定义错误，看看是不是头文件未包含
