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

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:

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

Thanks.

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

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

I had also the same problem,I think you didn't include the libz.dylib library.

To do so:

1. go to target section
2. Build Phases tab
3. Link Binaries With Libraries
4. click on + button
5. search libz.dylib
6. clcik on add button.

1.go to target section

2.Build Phases tab

3.Link Binaries With Libraries

4.click on + button

5.search libz.tbd (or libz.dylib)

6.click on add button.
