【问题描述】：

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" 并且还将 gl3w.h 添加到 /usr/include/GL/ 文件夹中。我做错了他们的事吗？

【参考方案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。

【讨论】：

我想静态编译opengl代码。他们还有其他可能的方式吗？

我认为这在 Linux 系统上是不可能的（这是我假设你在这里使用的）。 OpenGL 库非常庞大，我认为在某些情况下它们甚至可能是特定于供应商的。
