【问题描述】:
我正在使用 glfw 和 glew 创建窗口,它给了我链接器错误。我该如何解决。这是我第一次安装 glfw 和 glew,所以我可能错过了安装步骤。有什么帮助吗?
我只使用以下代码编译我的代码:
gcc main.c
我知道有一些链接器标志,但 glfw 和 glew 不是其中的一部分。
我使用 linux 和 gcc 编译器。
这是我的代码:
#define GLEW_STATIC
#include <stdio.h>
#include <stdlib.h>
#include <GL/glew.h>
#include <GL/glfw3.h>
#include <stdbool.h>
int main(){
glewExperimental = true;
if(!glfwInit()){
printf("failed to initialize GLFW\n");
return -1;
}
glfwWindowHint(GLFW_SAMPLES, 4);
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
GLFWwindow* window;
window = glfwCreateWindow(1024, 768, "Game", NULL, NULL);
if(window == NULL){
printf("Sorry to say this, but your OpenGL version must be 3.3 or above! Thanks for playing, but to continue you must update your video card drivers or if you use an old GPU you may have to replace it with a new one to play this game. I will be developing my game for OpenGL 1 and 2 soon so stay on touch.");
glfwTerminate();
return -1;
}
glfwMakeContentCurrent(window);
glewExperimental = true;
if(glewInit() != GLEW_OK){
printf("Failed to initilize GLEW");
return -1;
}
}
这是错误日志:

【问题讨论】:
-
很明显链接器找不到 OpenGL 库。因此,与其发布代码,不如描述安装时所采取的步骤。
-
我只是将头文件放在 /usr/local/include/GL 中,这就是我所做的。请告诉我是否需要导出链接器文件
-
我使用带有 gcc 编译器的 Linux(Linux Mint,如果这很重要的话)。我没有 IDE。
