In Windows do the following:

mkdir out
cd out
cmake -G "Visual Studio 14 2015 Win64" -DBUILD_FOR_UNREAL=1 ..
msbuild ALL_BUILD.vcxproj /p:Configuration=Release

The following binary files are generated:

  • out\prefix\bin\aws-cpp-sdk-gamelift-server.dll

  1. Thank you for your kind post 🙂 But I have an one question – I cannot compile with VS2017 not 2015 ;( Should I install 2015 to develop with gameLift?

  5. We tried to build the dedicated server as instructed. We tried with both the 4.18 and 4.19 sample, with the release version of unreal.

    We ran the command:
    RunUAT.bat BuildCookRun -project=”C:\Users\4DMACAU-G25VR\Documents\Unreal Projects\GameLiftSample_4.18\GameLiftSample.uproject” -noP4 -platform=Win64 -clientconfig=Development -serverconfig=Development -server -serverplatform=Win64 -noclient -nodebuginfo -build -cook -stage -pak -archive -archivedirectory=”C:\Users\4DMACAU-G25VR\Documents\Unreal Projects\GameLiftSample_4.18\Build”

    After it tried to build for a while, we got the same error in red each time, saying:
    ERROR: Command failed (Result:5): C:\UnrealEngine_release\Engine\Binaries\DotNET\UnrealBuildTool.exe GameLiftSampleEditor Win64 Development -Project=”C:\Users\4DMACAU-G25VR\Documents\Unreal Projects\GameLiftSample_4.18\GameLiftSample.uproject” “C:\Users\4DMACAU-G25VR\Documents\Unreal Projects\GameLiftSample_4.18\GameLiftSample.uproject” -NoUBTMakefiles -noxge -generatemanifest -NoHotReload. See logfile for details: ‘UnrealBuildTool-2018.06.21-16.49.37.txt’
    (see C:\UnrealEngine_release\Engine\Programs\AutomationTool\Saved\Logs\UAT_Log.txt for full exception trace)
    AutomationTool exiting with ExitCode=5 (5)
    BUILD FAILED

    Can someone please help?

  7. Hello,

    This is the best GameLift integration I’ve found so far! However, when trying to compile the server target from a source build of 4.20 with VS 2017, it gives a ton of “noexcept” errors. Any idea how to fix that?

    Thanks!

      • Thanks for the instant reply!
        If possible, can you also tell us what you did to “Game properties” (Key and Value pair in the bottom of a page) in “Matchmaking Configuration” of FlexMatch?

  14. Hi, does this work like the matchmaking system in for example PUBG, where the game starts when a specified number of players have joined a queue? And if more players wants to play, then the system will spawn another game instance? If this is not the way it works by default, would it be possible to do using this project? Thanks
