Undefined symbols for architecture i386 - Lipo err

I have compiled libclang.a for i386 and armv7. I'm able to build my ios app with i386 libclang.so but it can't be started because of ".dylib not found" error. Then i decided to create fat lib using lipo:

lipo -create ../i386/libclang.a ../armv7/libclang.a -output ../fat/libclang.a

and added fat library instead of i386.

Now i'm getting multiple build errors:

Does it mean lipo has created incorrect fat lib? How can i solve it? I need the app to run on both ios simulator and device.

PS.

MBA-Anton:llvm_34_ios_fat_installed asmirnov$ lipo -info ../iOS_Projects/StaticLibraryUsage2/StaticLibraryUsage2/libclang.a
Architectures in the fat file: ../iOS_Projects/StaticLibraryUsage2/StaticLibraryUsage2/libclang.a are: i386 armv7

PPS. Xcode build command-line:

I had to add all libLLVM*.a files in the project and the project was compiled successfully. But i have runtime error now:

dyld: Library not loaded: @rpath/libclang.dylib

  Reason: image not found

I'm not sure if it's related problem or i've solved that problem and now having another problem.
