编译错误Xcode 4.3.1-> OpenCv Framework [英] Compile error Xcode 4.3.1 ->OpenCv Framework

问题描述

我尝试使用MAcPort安装openCV，但是我检索到一些错误.因此，我下载了framework文件夹，并将其添加到xcode链接库中.现在，当我编写代码并构建代码时，我会收到此错误:

i've tried to install openCV using MAcPort, but i retrieve some errors. So i downloaded the framework folder an i added it to xcode link libraries. Now when i write my code and i build it i retrieve this error:

有人有同样的错误吗?你能帮助我吗???谢谢!!

Have anyone had the same error? can you help me??? thanks !!

推荐答案

您是否正在使用GCC 4.2编译器? XCode4默认使用LLVM，而openCV与此不兼容. 要检查单击项目，请转到构建设置"，搜索编译器".

Are you using the GCC 4.2 compiler? XCode4 uses LLVM by default, and openCV isn't compatible with it (yet). To check click on the Project, go to Build Settings, search for "compiler".
