编译时出现 GL3W 错误

Question

我正在尝试使用 gl3w 静态编译 opengl 程序，但在执行 g++ -Wall -o Code Code.cpp --static -ldl -lc -lglut -lGL -lGLU

时出现以下错误

我在#include "GL/glut.h" 之前包含了#include "GL/gl3w.h" 并且还在 /usr/include/GL/ 文件夹中添加了 gl3w.h。他们是不是我做错了什么？

Answer 1

您尝试使用的函数（例如，glBegin()、glVertex…() 等）是 OpenGL 兼容性配置文件的一部分。它们不存在于 gl3w 提供的 OpenGL 核心配置文件中。

听起来这可能不是您真正想要的。如果是这样，请不要使用 gl3w。
