Linking error when building TutorialHelloWorld in UnityPro4.6.0f3, Xcode5.0.2 (5A3005) and IOS 8.1.1

Question

I did my best to follow the tutorial "Webinar 10:Fundamentals of the Metaio SDK Unity" (https://www.youtube.com/watch?v=AW47EKRKEdw) but they use a different version of Metaio than me(I'm using metaio SDK (Version 22/05/2014)).

I manage to produce a project in Xcode imported form UnityPro. After I add: "libxml2.dylib" and "metaiosdk" to the Xcode project; and build the project, I get 130 errors and 7 warnings.

The warning just before the error list says: "ld: warning: directory not found for option '-L"/Users/900lbs-intern02/Desktop/metaio-test/Libraries"'

And the top error says: "std::__1::basic_string, std::__1::allocator >::insert(unsigned long, unsigned long, char)", referenced from:"

I tried to solve the warning by doing what is suggested in(‘ld: warning: directory not found for option’). Before building again, I cleaned the project(command+shift+option + k) and now I get the following 7 warnigs and 1 error(I will show the last warning and the error):

ld: warning: directory not found for option '-L"/Users/900lbs-intern02/Desktop/metaio-test/Libraries"' ld: library not found for -liPhone-lib clang: error: linker command failed with exit code 1 (use -v to see invocation)

Can someone tell me what is going on? Specially, how to solve the ld: warning: directory not found for option '-L"/Users/900lbs-intern02/Desktop/metaio-test/Libraries"' Warning?

I will appreciate anyone's help.

Answer 1

I solved the problem:

+First I upgraded to Xcode 6.1.1

+Then I added a couple of libraries/frameworks that where missing:

    -libc++.dylib

    -Security.framework

    -CoreImage.framework
