我得到错误LNK2005看似没有理由,或至少没有我能够识别。本质上,使用下面的代码我可以编译没有问题。看似随机的LNK2005与GLFW3错误
test.h
#define GLEW_STATIC
#include <GL\glew.h>
#include <GLFW\glfw3.h>
namespace test
{
//Objects and variables
GLFWwindow* window;
//Function prototypes
bool Initialize();
}
TEST.CPP
#include "test.h"
#include <iostream>
bool test::Initialize()
{
std::cout << "Initializing GLFW: OpenGL version 3.3 \n";
//Initialize GLFW
glfwInit();
//Set window properties (version 3.3, core profile, not resizeable)
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
//Create Window
window = glfwCreateWindow(800, 800, "Learn OpenGL", nullptr, nullptr);
if (window = nullptr)
{
std::cout << "Failed to create GLFW window \n";
glfwTerminate();
return false;
}
return true;
}
int main()
{
test::Initialize();
return 0;
}
然而,编译时几乎完全一样的东西(http://pastebin.com/VpPep9pM),与其他代码一起,它给人的错误:
错误LNK2005“struct GLFWwindow * window”(?window @@ 3PAU GLFWwindow @@ A)已在Main.obj OpenGL中定义D:\ Users \ Matthew \ documents \ visual studio 2015 \ Projects \ OpenGL \ OpenGL \ System.obj

所以,我想知道是什么原因造成的错误,我假设它有东西用“背景”来做。
