我使用的是最新版本的 opencv ( opencv 2.4.9 )，我必须有 -Objcflags，Core Plot(一个绘图框架)。
当我在其他标志中设置 -ObjC 时，我得到了很多类型的错误(实际上是 28 个):Undefined symbols for architecture i386如下:
Undefined symbols for architecture i386:

... etc
这与Bartosz Bialecki 是同一个问题，我尝试了建议的解决方案，但问题仍然存在。
有没有人有想法？
编辑:
这是我包含的所有框架:
最佳答案
问题解决了添加几个框架:
CoreVideo.framework, AssetsLibrary.framework, CoreMedia.framework.
这是包含的框架的完整列表:
关于ios - opencv2.framework 无法使用链接器标志 -ObjC 进行编译，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23634940/
