copy of a working target has "OBJC_CLASS_" errors

Question

I've a cocos2d project & got two targets "free" & "pro".

The "free" target runs all fine - so i made duplicate of it to turn it into "pro" but this duplicated target gives lots of "_OBJC_CLASS_" errors:

    Undefined symbols for architecture i386:

 ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

note: i've "cocos2d libraries" and it's target membership is switched on for both the targets!

all targets have already "standard architectures" set up including arm64 v7 & v7s - so may be i386 doesnt needs to be added separately. That didnt work out though. — Suman Maharjan, Feb 25 '16 at 05:11
Have a look at [this answer](http://stackoverflow.com/a/9438843/285242) and read the comments section as well. — 0xDEADBEEF, Feb 28 '16 at 19:21
