In my project, I do the following steps to make video call:
1. Download
https://www.linphone.org/releases/ios/liblinphone-iphone-sdk-2.2.4.zip
<http://www.linphone.org/releases/ios/liblinphone-iphone-sdk-2.2.4.zip>
2. Import liblinphone 2.2.4 to my project.
3. Import LinphoneManager.h/.m from linphone-iphone sample project.
Everything works great when HAVE_OPENH264 is not defined.
But I need H264, so set HAVE_OPENH264 in target build setting, and uncomment
libmsopenh264_init() in createLinphoneCore.
Then I can not build successfully. Errors are:
Undefined symbols for architecture arm64:

The arm64 is supported, so how can I fix this build error? (Disable arm64 in
"Valid Architectures" not work as well)_______________________________________________
