#lockdown Nick.Penwarden #rb none ========================== MAJOR FEATURES + CHANGES ========================== Change 3118534 on 2016/09/08 by Steve.Cano Certain non-looping SFX would not properly fire "Stop" events when the effect was finished, and therefore Sound Mixes that should end at the end of a SFX (such as ducking the BGM volume) were not properly finishing. Fixing the IsSourceFinished call to check the Position of the player to determine if we are actually done playing, which was not working properly before for PCM sounds. #jira UE-35016 #ue4 #android Change 3119125 on 2016/09/09 by Dmitriy.Dyomin Mobile launcher profile wizard: Fixed case where DLC will not be built if user selects non Development build configuration Fixed case where project maps will be empty if UE4 and project located on different drives Change 3122584 on 2016/09/13 by Allan.Bentham Add simple clip plane for planar reflections. #jira UE-32449 Change 3129390 on 2016/09/16 by Chris.Babcock Fixed ES 3.1 detection to also support devices returning ES 3.2 support (eg Note 7) #jira UE-35598 Change 3129867 on 2016/09/18 by Jack.Porter Fixed ES 3.1 detection to also support devices returning ES 3.2 support (eg Note 7) #jira UE-35598 Change 3131961 on 2016/09/20 by Allan.Bentham Fix missing editor widgets and gamma incorrectness when mobileHDR == false.

Problem is that the AssetRegistry uses in-memory metadata created on load for currently-loaded assets, but cooked content only has the serialized AssetRegistry and individual assets do not contain any metadata. Change 3143808 on 2016/09/28 by Steve.Cano Assume that the app starts in focus at startup and don't wait for an "APP_EVENT_STATE_WINDOW_GAINED_FOCUS" event to fire, as this event will not come down from SplashActivity since it is not a NativeActivity. If the user then rotates the device in Sensor or FullSensor orientation during SplashActivity and forces an eglSurface recreation, the initial Create will properly execute if we're "in focus". Previously, the create-destroy-create cycle would not properly execute due to the EventManager thinking the app was not yet in focus, and would cause the second create to get a 0x3003 error (EGL_BAD_ALLOC) #jira UE-35004 #ue4 #android Change 3144880 on 2016/09/29 by Jack.Porter Merging //UE4/Dev-Main to Dev-Mobile (//UE4/Dev-Mobile) Change 3146220 on 2016/09/30 by Dmitriy.Dyomin Adjusted device button style to make it more readable. #jira UE-21881 Change3146280on 2016/09/30 by Dmitriy.Dyomin Replaced IBuildManifest::ComputeDownloadSize with a new function Change 3146302 on 2016/09/30 by Allan.Bentham Added more stringent checks for ES3.1 compatibility #jira UE-36241 Change 3146435 on 2016/09/30 by Jack.Porter Prevent landscape grass being duplicated for PIE, causing ensure #jira UE-36531 Change 3147532 on 2016/09/30 by Chris.Babcock Use .sh extension for Android install scripts on Linux #jira UE-36669 #ue4 #android #linux Change 3149851 on 2016/10/04 by Dmitriy.Dyomin Mobile: Added custom depth rendering Mobile: Added support for CustomDepth and SceneDepth in post-process materails Change 3149852 on 2016/10/04 by Dmitriy.Dyomin Fixed comments for SortBasePass console variable Change 3149857 on 2016/10/04 by Jack.Porter Remove dead code in ProceduralFoliageComponentDetails.cpp Change 3149863 on 2016/10/04 by Jack.Porter Merging //UE4/Dev-Main to Dev-Mobile (//UE4/Dev-Mobile) Change 3149896 on 2016/10/04 by Dmitriy.Dyomin Fixed: SkyLight makes level entire green on Android devices #jira UE-34469 Change 3150102 on 2016/10/04 by Jack.Porter Bring Protostar 4.13 fixes back to Dev-Mobile Engine - MaxDescriptorSets = 16384 to prevent crash on Mali - Include texture formats in FRenderTargetLayoutHashableStruct to solve RT aliasing issue - Use ERenderTargetLoadAction::EClear for planar reflection target to work around Adreno issue - Default Adreno to SPIR-V Contents - Disable fog, reduce CSM shadow quality, fix device profiles - Add PSO cache Change 3150113 on 2016/10/04 by Jack.Porter Ensure automation testing screenshots have Alpha=255 (fixes automation screenshots on Mobile) Change 3150231 on 2016/10/04 by Jack.Porter Use a new SessionID GUID each time you use the launcher to launch a session.

How to build the cross-toolchain.
Big picture view, steps are described in detail later:
1.1 Build gcc-based cross-toolchain (we only need binutils/sysroot from it) on a Linux machine and copy them to a your Windows one. 1.2 Build/download clang on a Windows machine and add it to above toolchain.
How to use the cross-toolchain.
2.1 Set LINUX_MULTIARCH_ROOT environment variable to point to asbolute (Windows) path of the toolchain. 2.2 Restart Visual Studio and regenerate projects with UBT.
Building gcc-based cross-toolchain
Copy BuildCrossToolchain.sh together with all .config files to a Linux machine running Ubuntu 16.04. Run the script, which will clone a fork of crosstool-ng and will use it to perform so called "canadian cross", i.e. will build Linux-hosted toolchain which targets mingw64 first, and then will build Windows-hosted toolchain that targets Linux.
Note that the choice of kernel and binutils is pretty conservative and you are free to experiment (using "ct-ng menuconfig") if you need more recent ones. Not every combination is buildable though.
If the script finishes without error, the new toolchain will be copied to subfolder called CrossToolchainMultiarch of the current folder. Copy it to your Windows machine, e.g. to C:\CrossToolchainMultiarch
Building clang
Note that you can grab a pre-built clang from here: http://llvm.org/releases/download.html Detailed instructions how to build clang are given here: http://clang.llvm.org/get_started.html
To recap, you will need: cmake, python and a supported compiler (recent Visual Studio is Ok). Grab stable release of llvm and clang from here: http://llvm.org/releases/download.html and unpack it to your local folder (unpack llvm first, then unpack clang into llvm/tools subdirectory).
Use cmake to generate project files and then build Release (or MinSizeRel) x64 configuration of "install" (or INSTALL, if you are using Visual Studio) target. Here's an example how to do the above from comamnd line:
cmake -G "Visual Studio 11 Win64" -DPYTHON_EXECUTABLE=full_path_to_pythonw.exe -DCMAKE_INSTALL_PREFIX=path_to_copy_results_to ..\llvm devenv.exe LLVM.sln /Build Release /Project INSTALL
Having done that, copy from install directory the following
- bin/clang.exe
- bin/clang++.exe
- lib/clang/x.y.0/include
into all the architecture-specific toolchains (so their relative path from toolchain root stays the same).
Using toolchain to build UE4 Linux targets
Set environment variable (Control Panel->System->Advanced system settings->Advanced->Environment variables) LINUX_MULTIARCH_ROOT to absolute path to your toolchain, without trailing backslash, so it looks like this:
LINUX_MULTIARCH_ROOT=C:\CrossToolchainMultiarch
After you made sure that variable is set, you can restart Visual Studio and regenerate UE4 project files (using GenerateProjectFiles.bat). After this, you should have "Linux" available among Win32/Win64 configurations, and you should be able to cross-compile for it. Note that for the moment being, only Server (Debug Server, Development Server, etc) targets are buildable for Linux.
