GL3W和GLFW未定义的参考错误

-1

我在尝试使用GL3W和GLFW编写OpenGL应用程序时遇到了问题。我每次构建代码Code :: Blocks（使用GNU GCC编译器）时，都会遇到几个 “undefined reference”错误，以至几个gl3w *和glfw *函数。我检查了我的编译选项（链接：opengl32，glu32，gdi32;搜索目录/编译器：include [表示GL，GL3，GLFW和一些帮助标题];搜索目录/链接器：lib-mingw [glfw3 libraries]），一切看起来正确。这里是我的代码：GL3W和GLFW未定义的参考错误

所有错误未定义引用错误在任何帮助的建议

您需要编译gl3w.c并添加glfw.lib到链接库

（您添加 opengl32, glu32, gdi32同一个地方）
