You must rebuild it with Bitcode enabled (Xcode setting Enable_bitcode)

Here's a nice article about Bitcode's article introduction and configuration of Bitcode in iOS (HTTP://WWW.JIANSHU.COM/P/3E1B4E2D06C6)

There is also an article to resolve similar errors, but I have to verify it myself (http://www.jianshu.com/p/fe4b3a981618)

Xcode 7 Running Project error:

Error 1. Undefined Symbols for Architecture armv7:

"_compress2", referenced from:

+[umandeflated DeflatedDataPrefixedWith:level:source:] in libmobclicklibrary.a (UMDEFLATED.O)

Ld:symbol (s) not found for architecture armv7

Clang:error:linker command failed with exit code 1 (use-v to see invocation)

Error 2. does not contain bitcode. You must rebuild it with Bitcode enabled (Xcode setting Enable_bitcode), obtain a updated library from the vendor, or dis Able Bitcode for this target. For Architecture ARMv7

As a result of Xcode's own small problems, the project has been running a bug error 1. Then I will check the project Friends of the Library of the dependence of AH. Very sure to confirm that the library has been imported and inside the linked binary library.  (that is, build phases inside). And then constantly re-import clean many times or not. And then I collapsed. Then the Xcode reboot to run again the real error finally surfaced (after all, Xcode is Beta). is the content of error 2. The binary library of the Friend Alliance does not support Bitcode. Xcode supports Bitcode by default, and if supported, all of the binaries and frameworks must contain bitcode. As for what is Bitcode, see here: http://blog.csdn.net/soindy/ article/details/48518717

Workaround:

You must rebuild it with Bitcode enabled (Xcode setting Enable_bitcode)
