Current OSX builds don't contain required symbols

[zero1zero]

Sometime after ~version 11142 onwards, the OSX builds are throwing this linker error:

`Undefined symbols for architecture x86_64:

"_OBJC_CLASS_$_RTCDataBuffer", referenced from:

  objc-class-ref in libShared.a(DataChannel.o)

This is using build 11177.2.0. We also noticed that the library size shrunk from 24m to ~5mb. I've been trying to step through the commits that might have effected this but have been unsuccessful. Anyone have an idea?

Much thanks to @adamwulf for finding the version where the discrepancy was.

@thebehera could it possibly have been your commit here: https://github.com/pristineio/webrtc-build-scripts/commit/8c99f36489e58a4e852cd5860721ce2bb986dd1b

I'm seeing this as well. The last working version of the OS X libjingle_peerconnection CocoaPod is 11122.2.0. The versions from 11146.0.0 onward are missing the OS X symbols.

[zero1zero]

I ended up having to build by hand and link directly instead of using cocoapods :/

[schrockwell]

@zero1zero Did you have to use an older revision of the build scripts to accomplish this, or were you able to use HEAD?

[zero1zero]

I was able to just use HEAD if I recall correctly.

Experiencing the same issue (but everything works with version 11122.2.0).

[schrockwell]

I was able to compile from source on my own machine using the build scripts and the latest available version (v12566), and the OS X symbols are there and it works great. So, it's not clear to me whether (a) this has been fixed outright, or (b) the issue is localized to the build machine that is uploading the CocoaPods binaries.

I think that @thebehera can probably provide the definitive answer when he has the time.

I am facing same linker error. I had taken a sync (version 12673). I added new library to sample app of webrtc AppRTCDemo. Please see the attached screenshot of linker error that I am facing

@shantanu123 Did you find a solution? I am also stucked on this issue.
