我最近一直在尝试编译 C++ 代码并且不依赖 IDE， 我决定使用编辑器和命令行来编写和编译代码。
问题是我想制作一个 glfw 应用程序，但在链接 glfw3.lib 和 opengl32.lib 时出现错误:
a.exe : fatal error LNK1120: 92 unresolved externals
操作系统:Windows 7
编译器:clang
源代码/main.cpp:
#include <stdlib.h>
#include <stdio.h>
#include "window.h"
#define WIDTH 800
#define HEIGHT 600
int main(int argc, char* argv[]){
if (!Window_init(WIDTH, HEIGHT, "HELLOWORLD")){
printf("Problem loading window!\n");
return 1;
}
return 0;
}
src/window.h
#ifndef WINDOW_H
#define WINDOW_H
#include "GLFW/glfw3.h"
#define GLFW_INCLUDE_NONE
static GLFWwindow* window;
int Window_init(int width, int height, char* title);
void Window_update();
int Window_init(int width, int height, char* title){
if (!glfwInit())return 0;
glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
window = glfwCreateWindow(width, height, title,NULL, NULL);
if (!window){
return 0;
}
glfwMakeContextCurrent(window);
return 1;
}
void Window_update(){
}
#endif // !WINDOW_H
编译命令:
clang++ ..\src\*.cpp ..\src\*.h -L..\lib -lglfw3 -lopengl32 -I..\include\ -std=c++17
错误:
