Symbol(s) not found for architecture armv7 (Compiling w/ xCode)

Question

I'm having really annoying issues compiling my iOS Project. I keep getting the error "Symbol(s) not found for architecture armv7). Full error:

 ld: symbol(s) not found for architecture armv7

I did some research, but I haven't found the answer. I did find a possible reason, the plugins are out of date. Could this be the issue? I believe they are completely up to date.

So, what could be causing this, and how can I fix this?

Thanks for your help

Edit: Attempts to solve this, so far: Compile via armv6. Received different errors, see my response to meat5000's answer Compile via armv7s. Received different errors, see my response to meat5000's answer Update FB plugin, same errors.

Maybe this is still relevant.

Arm7 not supported, only 6.

Change it to 6 and it should work.

Even though that error is based on Applovin, it could be relevant. However, I do not see the option to change my arm version to 6, in Unity 4.3.4f1

Edit: I changed it via Xcode, let me try it out.

Edit2: Getting this error right now:

A lot of these warnings:

 `'+soft-float-abi' is not a recognized feature for this target (ignoring feature)`

And this error:

 ld: file is universal (5 slices) but does not contain a(n) armv6 slice: ../usr/lib/crt1.o for architecture armv6

Edit3: I changed it to armv7s, getting this error right now:

 ld: file is universal (2 slices) but does not contain a(n) armv7s slice: Librari
 es/libiPhone-lib.a  for architecture armv7s

Indeed, the first answer mentions 6/7 support in Unity :)

However this page contradicts what the other one says

@meat5000 So, what is your advice?

Did you try running in both modes?
