What the difference between 'Link binaries with libraries' and 'Libary Search Path' in Xcode project settings?

Library Search Path is the location where to search for your library files.

Link binaries is what the library or framework your project will link to.

  • Does it mean that it will link the searched library file? – VoidBzY Dec 26 '14 at 14:55
  • No，if you using the framework manually,you need to set the library search path so that Xcode will know where to find your framework. It just search,not add. – Zigii Wong Dec 26 '14 at 16:05
  • Are there any difference between static lib such as .a and dynamic lib such as .dylib. Because when I use boost, I just add the 'search' and the boost libs are all static(.a) and it works well. But when I use opencv2, there are a lot of dynamic libs(.dylib),if I don't add the 'link with binary', the compile will raise error. – VoidBzY Dec 26 '14 at 16:17

  • So I must add the dynamic library in the 'Link binary' to tell the compiler which dynamic library to link. And I can just need to add the static library in the 'Search', and the compiler will know which static library to link automatically. Is this right? – VoidBzY Dec 27 '14 at 13:00

    You can't add third party dynamic library for Apple will reject you application, but those within origin SDK is ok I think. So, If you want to add library, *General* - *Linked Frameworks and Libraries* so Here you go. – Zigii Wong Dec 27 '14 at 13:34
