问题
I'm trying to use glew in my Xcode project, but I'm getting this: Apple Mach-O Linker (Id) Error... Undefined symbols for architecture x86_64
I'm using the current version of glew that I downloaded from their sourceforge site.
回答1:
Here's what I did:
Install Glew via MacPorts. (in terminal run the command sudo port install glew)
In the Xcode project's build settings add the following:
- other linker flags:
-lGLEW - header search paths:
/opt/local/include/ - library search paths:
/opt/local/lib/
回答2:
You aren't linking with the GLEW library. You will probably have to add the directory, you installed GLES into, it to the 'library search path' settings of the Xcode project.
