Unreal Source code building errors in OSX Xcode

I am trying to build the source code 4.14.3 on a OSX Sierra 10.12.2 with XCode 8.2.1(8C1002).
When Xcode loads the solution initially it has 24 error triangles saying “Validate Project Settings” and “Update to recommended settings”. I have tried compiling on two different macs and get the same starting point. I tried reinstalling XCode. Re downloading the source code but keep getting same result. What am I doing wrong? Should I download some extra tools? Could this be the CLANG version mismatch? Is there a recommended/supported version of the software? I did follow the instructions on and tried searching on Google and in the forums…

Hi,

You are not doing anything wrong, this is just the way it is :wink:

In addition to the web pages, unreal also has some youtube videos which I found to be helpful. This video helped me a lot as well: UE youtube setup tutorial

Let us know if this did not help.

The video shows the process for Windows environment. I use windows too and I have sucessfully compiled on Win7 and Win10. So far so good. The problem is with OSX. I need to be able to publish for OSX and Win platforms.

Ignoring the warnings and compiling seems to have worked :slight_smile:
Incredible

As long as you follow the instructions for building on Mac on then you can safely ignore the warnings.

Are you sure you need to build from source? You can also install the binary release of the engine through the Epic Games Launcher.
