How to link to libz and libsqlite in xcode 7 beta?

Question

I got linkage error like:

   +[WeChatApiUtil DecodeBase64:] in libWeChatSDK.a(WeChatApiUtil.o)
  "_deflate", referenced from:
      +[MTAWXOHelper GZip:Out:] in libWeChatSDK.a(MTAWXOHelper.o)
  "_deflateEnd", referenced from:
      +[MTAWXOHelper GZip:Out:] in libWeChatSDK.a(MTAWXOHelper.o)
  "_deflateInit2_", referenced from:

But I've already added those library to my target. But currently all those library have different extension .tbd.

Any idea? Thanks.

There is a known issue in XCode 7 while linking tbd files. Here is the link to the apple developer forum answer on how to link tbd files in XCode 7 - https://forums.developer.apple.com/message/8609#8609

[Snippet from the link is available below]

This is a known issue in the Xcode 7 beta.

To work around this issue for now, please:

• Delete all references to .tbd files from either your linked libraries phase, or from the copied bundle resources phase (where they sometimes will be added).
• Add the library you want to link manually to the "Other Linker Flags" build settings, by adding the argument: -l for each library you want to link (for example, add "-lsqlite3" (without quotes)).

For those who are curious, the .tbd files are new "text-based stub libraries", that provide a much more compact version of the stub libraries for use in the SDK, and help to significantly reduce its download size.
