当我通过链接器运行我的 C++ OpenGL 程序时，我遇到了大量的链接器错误（包括在下面）。我编译不依赖 GLFW 的 OpenGL 程序没有问题。我不太确定从哪里开始，因为我在 Mac 上做了很少的 C++/ObjC 开发——有什么想法吗？谢谢！

正在运行的命令是：

g++ -framework Carbon -framework OpenGL -framework GLUT -lglfw -framework AGL -arch i386 display.o voxels.o -o cubile

错误是：

解决了它——当新版本的 GLFW 使用 Cocoa 时，我正在链接 Carbon。更换-framework Carbon解决-framework Cocoa了问题。
