Q: Xcode : Linker command failed with exit code : any idea??

Hello everybody,

I'm trying to implement a programme in C++ using Xcode 6.1.1.

in my project I have created different files with .cpp and .h extensions.

but whenever I try to compile, I got the message in the attached photo below.

Does anyone have an idea why do I get this message ?

Thank u all for your time

MacBook Pro, OS X Yosemite (10.10.1)

I'm guessing it was because you have duplicate symbols. It is probably something defined in a header file that should be in a source file.

I had this issue and the reason I found was the following:
- in my appDelegate.h I had a const object defined 'const int kMaxRecordsOnDevice = 1;'
- it should have been a static declaration i.e. 'static int kMaxRecordsOnDevice = 1;'

This solved my issue
