Android support for installation build generates compiler/linker errors

Attempting to make an installation build using the BuildGraph system on Windows 10 using Visual Studio 2017 will generate errors.

System/User Environment Variables:

ANDROID_HOME=D:\SDKs\Android\NVPACK\android-sdk-windows
ANDROID_NDK_ROOT=D:\SDKs\Android\NVPACK\android-ndk-r14b

Using the following command-line:

Engine\Binaries\DotNET\AutomationTool.exe BuildGraph -target=“Make Installed Build Win64” -script=Engine/Build/InstalledEngineBuild.xml -set:WithIOS=false -set:WithTVOS=false -set:WithAndroid=true -set:WithHTML5=false -set:WithLinux=false -set:WithMac=false -set:WithWin32=true -set:WithWin64=true -set:WithPS4=true -set:WithSwitch=true -set:WithXboxOne=true -set:WithDDC=false -NoSign

Here are some of the errors that I’m encountering during the build process:

As you can see from some of these errors above, the *.o files it’s searching for seem to be in the following location:

I had same problem and solved by fixing code. I made a PR to engine repository but it seems not merged yet. See and apply the fix and you should get build back work.
