Undefined symbols for architecture i386: "_deflate", referenced from PlatCompress(enumCompressOperation, CompressCookie*, void*, long) in libMo.a

Question

I'm doing native iOS application using SUP.As per documentation; i have included the library and given the link path in Xcode. While building getting following error:

Undefined symbols for architecture i386:

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Please help me how to solve this error.I'm new to native iOS development using SUP.

Thanks.

Answer 1

I also had a same error.

Add libz.dylib to framework from the target -> Build Phases tab -> Link Binaries With Libraries,

hope that will work for you.

Note: If libz.dylib not found, try adding libz.tbd

Answer 2

Starting with Xcode 7, instead of adding libz.dylib, you should do this:

• Go to the project Build Settings tab
• Search for Other Linker Flags
• Add -lz as a linker flag (see screenshot)
• In the Product menu, select Clean before building again
