在OSX中与GLFW链接的问题 [英] Problems linking against GLFW in OSX

问题描述

通过链接器运行C ++ OpenGL程序时，出现很多链接器错误(包括在下面).我编译不依赖GLFW的OpenGL程序没有问题.我不确定从这里开始应该走什么路，因为我在Mac上很少进行C ++/ObjC开发-有什么想法吗?谢谢！

I'm getting a ton of linker errors (included below) when I run my C++ OpenGL program through the linker. I have no problem compiling OpenGL programs that don't have a dependence on GLFW. I'm not really sure where to go from here, because I've done very little C++/ObjC development on Mac -- any ideas? Thanks!

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:

推荐答案

解决了它-当GLFW的较新版本使用Cocoa时，我与Carbon进行了链接.用-framework Cocoa替换-framework Carbon解决了该问题.

Solved it -- I was linking against Carbon when the newer versions of GLFW use Cocoa. Replacing -framework Carbon with -framework Cocoa solved the problem.
