[UWP] [IL2CPP] Deploy Issue

Hello everyone.
I am experiencing an issue with deploying a project as a Universal Windows Platform application.
If i try to Build&Run the project, i get the following error :

Exception: Failed to build Visual Studio project using arguments 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\MSBuild.exe "C:\Users\Nicolo Giani\Documents\LiveStreamTest\LiveVideoStreamTest\App\LiveVideoStreamTest.sln" /nologo /maxcpucount /p:Configuration=Master /p: Platform=x86 /p:SolutionDir="C:\\Users\\Nicolo Giani\\Documents\\LiveStreamTest\\LiveVideoStreamTest\\App\\" /t:Build /clp:Verbosity=minimal'.
Output: Building GameAssembly.dll with MsvcWinRtToolChain.

I also tried to deploy the application by deploying the UWP project in the Visual Studio solution built by Unity, but this is what i get in the output window:

Error MSB3073: the command ""C:\Users\Nicolo Giani\Documents\LiveStreamTest\LiveVideoStreamTest\App\Il2CppOutputProject\\IL2CPP\build\il2cpp.exe" --libil2cpp-static --compile-cpp -architecture=x86 -configuration=Release -platform=winrt -outputpath="C:\Users\Nicolo Giani\Documents\LiveStreamTest\LiveVideoStreamTest\App\\build\bin\Win32\Release\GameAssembly.dll" --data-folder="C:\Users\Nicolo Giani\Documents\LiveStreamTest\LiveVideoStreamTest\App\\build\bin\Win32\Release\\" -cachedirectory="C:\Users\Nicolo Giani\Documents\LiveStreamTest\LiveVideoStreamTest\App\\build\obj\il2cppOutputProject\Win32\Release\\" -generatedcppdir="C:\Users\Nicolo Giani\Documents\LiveStreamTest\LiveVideoStreamTest\App\Il2CppOutputProject\\Source" --additional-defines=WINDOWS_UWP --additional-defines=UNITY_UWP --additional-defines=UNITY_WSA_10_0 --additional-defines=UNITY_WSA --additional-defines=UNITY_WINRT --additional-defines=PLATFORM_WINRT -dotnetprofile=net45 -verbose --map-file-parser="C:\Users\Nicolo Giani\Documents\LiveStreamTest\LiveVideoStreamTest\App\Il2CppOutputProject\\IL2CPP\MapFileParser\MapFileParser.exe"" exited with code -532462766.

I guess the error is related to building the GameAssembly dll, but i have no idea on how to solve it :-(
I'm using Unity 2017.3.0f3 and with Visual Studio 2017 v15.5.6.
My current player settings are the following :

• Scripting runtime : .NET 4.6
• Scripting backend: IL2CPP
• API compatibility level: .NET 4.6

Just for additional information, in the project am using the following plugins from Asset Store:

• https://assetstore.unity.com/packages/tools/video/ump-pro-win-mac-linux-webgl-83281
• https://assetstore.unity.com/packages/3d/characters/youtube-live-stream-for-hls-players-107576

Thank you in advance for any help

That is some excellent support right there.

 

Hi,
I'm using Unity 2020.3.25 and I'm trying to build a VR app targeting PC & Standalone in IL2CPP scripting backend but the build fails with the following log:

Things I tried:
1. I tried deleting the IL2CPPBuildCache and IL2CPPCache in my library folder -> Didn't work
2. I tried restarting my PC and Unity (found in one of the forums) -> Didn't work
3. I tried to switch to Mono and generate a build, it was built successfully. But the app is blank totally.
I've been browsing for an apt answer for 2days, but I haven't found one. Please help me resolve this issue

 

Thanks for the quick response.
But my project has no such class. I think this is an auto-generated class while building in the IL2CPP scripting backend. My project runs well in the editor, and I just don't know what's going wrong while building the project.

 

I'm currently being blocked here with this error and I'm unable to generate a successful build. Can anyone help me resolve this issue? Thanks in advance!!

 

Hello, I think I'm running into a similar issue to the above, which started to happen after I imported an external package. Running it in the editor works fine, but when I try to build, I get the following error.

Following the advice above, I tried to search for any C++ files that may have been autogenerated, "dl____" keywords, as well as "IL2", but nothing comes up.

What should I do in this case? Thanks in advance!
