WebRTC.framework for macOS

[Thomas Baastrup Jacobsen]

Hello folks,

I'm having trouble building a WebRTC.framework for macOS. (I have no issues building one for iOS though)

It seems that there isn't created a ninja build target for the framework when creating build files for mac with gn, ie. a 'rtc_sdk_framework_objc' target isn't created.

Going through the steps explained here: https://webrtc.org/native-code/ios/

It says "The same checkout can be used for both Mac and iOS development". I have also tried with the steps explained here: https://webrtc.org/native-code/development/

fetch --nohooks webrtc_ios

gclient sync

gn gen out/macos --args='target_os="mac" target_cpu="x64" is_component_build=false'

And then:

ninja -C out/macos rtc_sdk_framework_objc

ninja: Entering directory `out/macos'

ninja: error: unknown target 'rtc_sdk_framework_objc'

Is there a different recommended way for implementing WebRTC on macOS?

Thanks,

Thomas

Hi Thomas. Currently building the WebRTC framework for mac is not supported. We don't have a use case for it and it would be hard for us to maintain as it's not used.

See https://bugs.chromium.org/p/webrtc/issues/detail?id=6706 for a discussion on this topic.

Hi Kári,

That's unfortunate to hear. Thanks for your quick response though.

Cheers,

Thomas

I was able to get WebRTC working on Mac OS using a modified version of the Makefile here:

https://github.com/mpromonet/webrtc-streamer

Just had to update one of the include paths and add in a bunch of frameworks when linking.

Hi,

I am trying to build webrtc_ios on mac but it failing with a lot of errors. Can you still build on mac with the latest XCode and macOS?

[Adrian B]

I don't know. It's been a long time since I've done anything with WebRTC. Good luck.

tools_webrtc/ios/build_ios_libs.py is what you need.
