I have my machine setup with the latest stable Xcode as well as the beta version for 8.3. The dependencies build process fails like so:

Setting up toolchain for ios.
ERROR: No SDK detected, looking in /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform
Failed building...libusrsctp

Looking in that particular folder reveals I have a folder without SDK version number, and one for 8.2 only. I modified the setup_tool_chains.sh script to include lines for 8.2 and 8.3 to get back on my way. I imagine this is entirely my fault for having multiple Xcodes, however it may be something to consider testing for, complaining about or just expecting :)

There are a lot of changes that we need and backporting all of them will be rather risky.

I'm working on updating the build scripts accordingly. Also this will then build openh264 from gst-plugins-bad.

Recently contriibutors has updated openSSL version but forgot to update two scripts.

Please to update OPENSSL_VERSION variable to 1.0.2 on files:
build-gst-plugins-bad.sh
build-libsrtp.sh

When the build scripts come down to building pygobject (Mac OSX Yosemite), it ends up with this error:

Any idea what could be done ?
