gstreamer ios教程中的错误

Question

I downloaded gstreamer-1.0-devel-1.8.1-ios-universal-pkg and am trying to compile and run the GStreamer iOS Tutorials. I get an

implicit declaration of function get_registry_get_default is invalid in C99

error in gst_ios_init() on line 1028. If I have Xcode "fix" it, I then get

Could not create compact unwind for _ffi_call_unix64: does not use RBP or RSP based frame

and then a bunch of undefined symbols for architecture x86_64.

Answer 1

You have a typo there: It's not get_registry_get_default() but gst_registry_get_default(). That's what XCode is probably fixing for real there.

What are the other undefined symbols?
