在OSX中连接GLFW时遇到的问题

c++openglglfw
3

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错误（如下所示）。我没有问题编译不依赖GLFW的OpenGL程序。因为我在Mac上很少进行C++/ObjC开发，所以我不太确定该怎么做--有什么建议吗？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

错误信息为：

你是在Xcode中构建这个项目还是通过命令行或者make文件呢？ - Michael Dautermann
它是从Makefile运行的。我忘记在问题中添加命令了 - 我现在会编辑并添加它。 - Haldean Brown
Foundation 没有，但 Cocoa 有。感谢您的帮助！ - Haldean Brown

解决了——我在链接时使用的是Carbon，而新版本的GLFW使用Cocoa。将-framework Carbon替换为-framework Cocoa解决了这个问题。
有没有人或者你知道如何在Cmake中添加这些标志？ - Brian Yeh
