_iconv linker error help! (RESOLVED)

cocos2d-x
#1

Hi,
I decided to update my game to the latest cocos.
It is built with 3.7 (on Mac)
So I though I’d go step at a time - so update to 3.8 first.
Replaced by (symbolic linked) 3.7 with 3.8
Clean
Build
And I get

Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64

I have tried everything I can find to fix it = with no luck…
If I add -liconv to “Other Linker Flags” for the cocos project - it makes no difference (I currently have -lsqlite3 -lz -liconv as my other linker flags)

Some posts talk about adding libconv.dylib - but I don’t have one of those.

Please help. Cleaning and rebuilding takes ages - and I’m pretty clueless as to what I’m doing here!

:smile:

** UPDATE & RESOLUTION **
Well, it was a case of PEBCAK - I had added the -liconv to the Mac build then built for IOS

Arghhhh!

Hi @Maxxx

I was checking some cocos studio samples recently and found the issue exactly as yours.
the base project was designed back in Cocos 3.2 I believe.

I have added new framework cocos 3.10 and the issue came.
but once I have added -liconv to Other Linker Flags, the errors went and I was able to build successfully.

Please check it once, and let me know, it should work.
may be clean and run, it will take some time but I am sure it will work, tested yesterday.

Pabitra

#3

I added -liconv to both my project and the cocos2d_libs project

Still get the _iconv errors

Cleaned, and rebuild many times - even closed XCode and re-opened

If I change back to 3.7 it builds fine

#4

Add libiconv as a framework to your project and you should be all set.

#5

The question is, how do I do this?

#6

Yes, XCode 7.x changed the name.

#7

Interesting.
So I can either include that or add a linker flag -liconv

I will swear I tried adding libiconv.tbd previously with no luck!

Thanks!
