VuforiaSamples, XCode 5.1.1, SDK 6.1 and 7.1

By opelfahrer79 on Wed, 07/16/2014 - 12:19
Hi,

I'm trying to compile the VuforiaSamples using XCode and the 7.1 sdk. 
I also have the 6.1 installed, which works flawlessly. However, for the 7.1 
version, I get this long list of errors during linking:

Undefined symbols for architecture armv7:

Any help is highly appreciated!Regards...

I finally got rid of the error by adding libstdc++.6.0.9.dylib to the list of libraries to link. I'm not sure why this is necessary, however...
