First of all, I don't know if we have a baseline iOS which we want to support -- I think we should begin by setting that up as we do e.g. with WINVER.

Most of the errors can be fixed by building the relevant Obj-C sources with the -fmodules flag, letting the compiler inject the framework flags as appropriate. This can fix all but -lresolv for GThreadedResolver, and -liconv for libass et al.

There is one which cannot be fixed by hand, so I guess I broke it when prelinking librsvg:

Undefined symbols for architecture arm64:

Expected Behavior

Linking should automatically succeed (barring the missing symbols, which will be the subject of another issue).

Observed Behavior

I have to play matchmaker between missing functions and CMake, finding which framework exports it.

Setup

  • Operating System: macOS 12.7.6 against iPhoneOS 16.2.sdk
  • Device: Mobile **
  • GStreamer Version: 1.25.0.1
  • Command line: N/A

Steps to reproduce the bug

  1. open terminal
  2. clone my branch: https://gitlab.freedesktop.org/amyspark/gstreamer/-/blob/port-ios-examples
  3. navigate to subprojects/gst-examples/playback/player/ios/GstPlay/
  4. issue cmake .. -GNinja -DCMAKE_FRAMEWORK_PATH=<path to GStreamer.framework's install folder> -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_ARCHITECTURES=arm64

How reproducible is the bug?

Always
