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

问题

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.

I have two project using zlib, one which finds it to link, one which doesn't. I set them both up by using the "+" in "Linked Frameworks and Libraries". I finally figured out how to fix the non-working one:

Remove all links to zlib that you added in previous attempts
Open Finder, head to /usr/lib, and drag the libz.dylib alias into your project's Frameworks folder
Compile. This worked on 2015/08/23 for me.
