ZBar: Undefined symbols for architecture armv7

I am using the zBar library on an iOS 8 project and I get these compiler warnings:

Undefined symbols for architecture armv7:
  "_iconv", referenced from:
      _qr_code_data_list_extract_text in libzbar.a(qrdectxt.o)
  "_iconv_open", referenced from:
      _qr_code_data_list_extract_text in libzbar.a(qrdectxt.o)
  "_iconv_close", referenced from:
      _qr_code_data_list_extract_text in libzbar.a(qrdectxt.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I followed this suggestion putting the frameworks in order and this is how I import them:

I assume that the library libzbar.a was created for armv6 processors and as I am targeting iOS 8 with armv7 it conflicts. Is there a way to resolve this without me changing my project architecture targets?

Try to add libiconv.dylib in frameworks. I dont think it is armv7 problem. It should run after adding missing framework.
