I have just downloaded the gstreamer ios binaries from https://gstreamer.freedesktop.org/data/pkg/ios/1.8.1/. and the gstreamer sdk from https://cgit.freedesktop.org/~slomo/gst-sdk-tutorials/ (which has not been updated for 7 months? -- is there a newer version)?
When I enable the following features in gst_ios_init.h, i am unable to resolve the symbols as follows. Is there a newer SDK? I don't need liveadder or fragmented or editing tools, but the ios compression support seems like it would be useful.
When I enable:
#define GST_IOS_PLUGINS_EFFECTS
I get:
Undefined symbols for architecture x86_64:

Just add VideoToolBox framework to your project.
This is because your gstreamer framework installed is not the same as the tutorial. Copy according gst_ios_init.h and gst_ios_init.m to tutorial project will fix the issue

I followed the following guide: How to remove CocoaPods from a project? because my podfile was giving me a lot of trouble. Now I'm getting this error message and have no idea what's going on

I took the following steps:
Create a brand new swift single view application.
Add a pod file that expresses a dependency on Firebase
Install the pods
Open the resultant workspace and build for simulator
The builds succeeds
I then repeated these steps except that in step 1 I created a brand new swift cocoa touch framework. Now the builds fails.
As you can see below, Firebase is referencing undefined symbols. And those symbols are mostly ones that I recognize and would expect to be present: UIScreen, UIWebView, UIView, etc.
I suspect that this all has something to do with the fact that Firebase is a static library (as is pointed out here by Mike McDonald as a reason why Firebase cannot be used with Carthage).
I am at the limit of my understanding of the differences/consequences of applications, frameworks, and libraries. Can anyone help me to understand what is going on here?

You have to link libyuv.a to your project.

Any idea how we can fix that issue? I checked the files in Unity and it seems everything is imported fine.
Fixed it somehow through reimporting the whole Fabric SDK in Unity - so deleting all files regarding Fabric and Crashlytics in the project and then importing Fabric again.
I'm missing something minor here in my project using the OpenCV framework from a working demo.
Steps to reproduce:
Download the example app from http://aptogo.co.uk/2011/09/opencv-framework-for-ios/
Create a new Titainum iOS module with titanium create --platform=iphone --type=module --dir=. --name=opencv --id=opencv
Open the XCode project, drag in the OpenCV framework from the FaceTracker app and the other required frameworks.
Add OTHER_LDFLAGS=$(inherited) -framework OpenCV to module.xcconfig
Create new TiUIView and TiUIViewProxy classes named OpencvView and OpencvViewProxy.
In the new OpencvView class, instantiate a UIViewController that uses OpenCV.
The build will build the Titanium module, but when I try to run the module test harness, I get these errors for OpenCV objects:

I have similar errors. And just changing "build setting" does not help.
Finally, I solved this problem by adding some framework like coreMedia, coreVideo, etc.
These frameworks, however, are not used in my code.
So I guess openCV needs these frameworks. But I don't know why.
Hope this will help:)
I had a similar problem with the default apple llvm compiler on Xcode 4.5.1. Try changing it to gcc (from your build options) and see if this works.
