Undefined symbols for architecture arm64

[Haiyong Zhang]

Hi,

I am using Xcode 7.3 and GStreamer iOS 1.8.1. I created a project by using
"GStreamer single view template". However, I got error messages when I
tried to use #define GST_IOS_PLUGINS_EFFECTS.
The error messages are as below. Please help me figure out how to fix this
problem Thanks.

I think this is related to the iOS version you're targetting in XCode.
Try targetting iOS 6, IIRC it uses a different C++ ABI if you target
something newer... or something along those lines.

It works. Thank you very much.
