How to Disable IOSTargetPlatform during Compilation

Hello everyone. I’m trying to hack on Unreal 4.8 to make Android targeting work with Ubuntu Linux. I made a good progress as AndroidTargetPlatform and everything else gets compiled successfully but I get error for IOSTargetPlatform.cpp. I don’t even want target iOS so I was wondering if there was a way to disable it to circumvent the error. There compilationg error is like this:

/bin/sh  -c '/bin/sh "/home/james/UnrealEngine/Engine/Intermediate/Build/Linux/x86_64-unknown-linux-gnu/UE4Editor/Development/FixDependencies.sh" && touch "/home/james/UnrealEngine/Engine/Intermediate/Build/Linux/x86_64-unknown-linux-gnu/UE4Editor/Development/UE4Editor.link"'

I would appreciate it if anyone have solution or idea for this. Thanks :slight_smile:

How did you include the AndroidTargetPlatform to the Linux build? Did you copy paste in the TargetPlatform.Build.cs? If so, you probably included IOSTargetPlatfrom on accident. Check that real quick and see if you have included IOSTargetPlatform in the Linux section of that file.
