ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
But the project compiled successfully to simulator , the error happen when i compiled the project to real device .
Finally i found the problem : libsqlite3.dylib that i used compiled for armv6 not 7 , so i just download xcode dmg file 4.3 and extract the lib from it .
