AssetBundle build issue with new Simulator version 2019.10

[Roman-jj]

Hi, after updating to the newest version on Windows, I can't build AssetBundles anymore.

I saw that now it should be possible to build for cross-platform support, but when I try to build I first get a warning saying

Library\PackageCache\com.unity.inputsystem@0.2.10-preview\InputSystem\Plugins\PlayerInput\PlayerInput.cs(399,27): warning CS0109: The member 'PlayerInput.camera' does not hide an accessible member. The new keyword is not required.

then an error

Building an AssetBundle for target 'LinuxStandaloneSupport' is not allowed because the required module is not installed. UnityEditor.BuildPipeline:BuildAssetBundles(String, AssetBundleBuild[], BuildAssetBundleOptions, BuildTarget) Simulator.Editor.Build:RunAssetBundleBuild(String, List1, List1) (at Assets/Scripts/Editor/Build.cs:397) Simulator.Editor.Build:OnGUI() (at Assets/Scripts/Editor/Build.cs:165) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

and another error

FileNotFoundException: Could not find file "C:\Users\joerger\LGSVL\simulator\AssetBundles\e5fd4294-d90b-45f1-a0c0-27e54437b526_vehicle_main_linux" System.IO.FileStream..ctor (System.String path, System.IO.FileMode mode, System.IO.FileAccess access, System.IO.FileShare share, System.Int32 bufferSize, System.Boolean anonymous, System.IO.FileOptions options) (at <7d97106330684add86d080ecf65bfe69>:0) System.IO.FileStream..ctor (System.String path, System.IO.FileMode mode, System.IO.FileAccess access, System.IO.FileShare share) (at <7d97106330684add86d080ecf65bfe69>:0) (wrapper remoting-invoke-with-check) System.IO.FileStream..ctor(string,System.IO.FileMode,System.IO.FileAccess,System.IO.FileShare) System.IO.File.Open (System.String path, System.IO.FileMode mode, System.IO.FileAccess access, System.IO.FileShare share) (at <7d97106330684add86d080ecf65bfe69>:0) ICSharpCode.SharpZipLib.Zip.StaticDiskDataSource.GetSource () (at :0) ICSharpCode.SharpZipLib.Zip.ZipFile+ZipUpdate.GetSource () (at :0) ICSharpCode.SharpZipLib.Zip.ZipFile.AddEntry (ICSharpCode.SharpZipLib.Zip.ZipFile workFile, ICSharpCode.SharpZipLib.Zip.ZipFile+ZipUpdate update) (at :0) ICSharpCode.SharpZipLib.Zip.ZipFile.RunUpdates () (at :0) ICSharpCode.SharpZipLib.Zip.ZipFile.CommitUpdate () (at :0) Simulator.Editor.Build.RunAssetBundleBuild (System.String folder, System.Collections.Generic.List1[T] environments, System.Collections.Generic.List1[T] vehicles) (at Assets/Scripts/Editor/Build.cs:413) Simulator.Editor.Build.OnGUI () (at Assets/Scripts/Editor/Build.cs:165) System.Reflection.MonoMethod.Invoke (System.Object obj, System.Reflection.BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) (at <7d97106330684add86d080ecf65bfe69>:0) Rethrow as TargetInvocationException: Exception has been thrown by the target of an invocation.

I can get around the error by commenting out lines 391-401 and line 410 in build.cs, so it's not an issue for me, but I'm not sure if it's a bug or just some requirements that I don't have installed on my system

We recently changed how we build map/vehicle bundles. Before they were platform dependent - Windows vs Linux. Now they are built both at same time into one package. That means your Unity installation needs to have Windows and Linux support installed - you choose this during installation. You should simply run installation again and choose to install Linux support. Then build will succeed.

Ah thanks, then I'll just do that.

Could you update doc of build from source instructions ? https://github.com/lgsvl/simulator/blob/master/Docs/docs/build-instructions.md Mention that installing Unity with necessary Windows & Linux build supports.
