WebRTC and iOS simulator

[Andrey Moskvin]

Hi everybody!

I'm working on WebRTC integration into framework for video/audio calling. I've successfully built *.a static libraries for iOS device - but I have following errors when trying to build for iOS simulator:

I need have both iOS sim and device libraries to make it possible to launch app on any iOS platform (sim or device)...

Have anybody experienced such problems?

I've used following guide:

http://ninjanetic.com/how-to-get-started-with-webrtc-and-ios-without-wasting-10-hours-of-your-life/

Thanks for attention.

Best regards,

Andrey Moskvin

Hi Andrey,

I just tried to build WebRTC for iOS and got exactly the same errors. Were you able to figure those out?

[Cameron Webb]

While it's not a direct solution to your problem: is there any reason you absolutely have to use simulator instead of device? I suspect the issue lies in the fact that the simulator, is well, a simulator and doesn't necessarily have the same specifications on low-level as device.

Admittedly, I ran into same issues in the past, but if you got it working on the device then don't smash your head on keyboard trying to get simulator stuff to work. In due time I'd guess that the webrtc folks will have that all squared away. 

[Misha K]

Cameron, I don't really care about the simulator, it's just the first thing that I tried to build. 

The workaround for the errors above is to exclude VP9 codec by modifying the libvpx.gyp file in trunk/third_party/libvpx/ from this

'libvpx_build_vp9%': 1

to this

'libvpx_build_vp9%': 0

Thanks Ami.

just tried to build latest src for iOS simulator and it works

did you fix this?

Or maybe it depends on user's environment

See Ami's comment, issue 3126 fixed the build issue for ios simulator.
