How to exclude undefined symbols from RapidEars framework linking?

Question

I added a framework to my Xcode 4.4 project by drag-and-drop of the framework onto the project in the Project Navigator.

I am getting linker errors for undefined symbols on Xcode.

Undefined symbols for architecture armv7: "_returner", referenced from: _should_be_returned in RapidEarsDemo(multisphinx_re.o) "_input_sample_rate", referenced from: -[PocketsphinxController(RapidEars) startRealtimeListeningWithLanguageModelAtPath:andDictionaryAtPath:] in RapidEarsDemo(PocketsphinxController+RapidEars.o) -[ContinuousModel(RapidEars) realtimeListeningLoopWithLanguageModelAtPath:andDictionaryAtPath:] in RapidEarsDemo(ContinuousModel+RapidEars.o) -[RECommandArray commandArrayForlanguageModel:andDictionaryPath:isJSGF:] in RapidEarsDemo(RECommandArray.o) ld: symbol(s) not found for architecture armv7

I ran "nm" on the RapidEarsDemo framework file, and I only see _input_sample_rate for i386. How do I specify not to include this symbol for armv7?

"nm" doens't show _returner at all.

In Build Phases -> "Link Binaries with Project", I made sure that my new framework is listed there. I already did a clean and rebuild.

Any suggestions? Your help would be greatly appreciated!

You are using an old version of OpenEars and updated version of Rapidearsdemo, just update to the current OpenEars version. — sschunara, Nov 12 '12 at 19:42

May be you are missing some header files of library to include in project.

Missing headers cause failures during compiling, not during linking. – NSGod Nov 04 '12 at 23:59

The reason was that I included two frameworks. Framework A referred to framework B. I was using version 1.1 of A, but version 1.2 of B. Thus A expected symbols to exist in B, which did not exist in that version.

Running "nm" to list the symbols was enlightening.

Halle from Politepix here, glad you got this cleared up on your own. To clarify for others who might have a similar issue, RapidEars is a plugin for OpenEars and it has a minimum version of OpenEars that it can be run with. – Halle Nov 05 '12 at 07:33

I would try under Build Settings -> Other Linker Flags add "-all_load"

Just wanted to mention that for OpenEars and its plugins specifically there is never a need to use -all_load. – Halle Nov 05 '12 at 07:39
