Windows build fails

Hi all

I’m using Unity 2020.1.3f1

today something weird happened in my project. my visual studio 2019 enterprise edition got messed up so I lost the attach button, but I can still go to edit → attach to unity

also when I’m trying to build a windows version I’m getting the following error

Failed running D:\Program Files\Unity\Hub\2020.1.3f1\Editor\Data\il2cpp/build/deploy/netcoreapp3.0/il2cpp.exe --convert-to-cpp --emit-null-checks --enable-array-bounds-check --dotnetprofile="unityaot" --compile-cpp --libil2cpp-static --platform="WindowsDesktop" --architecture="x86" --configuration="Release" --outputpath="D:\Projects\TempName\Temp/StagingArea/Data\Native\GameAssembly.dll" --cachedirectory="D:\Projects\TempName\Assets\..\Library/il2cpp_cache" --baselib-directory="D:/Program Files/Unity/Hub/2020.1.3f1/Editor/Data/PlaybackEngines/WindowsStandaloneSupport\Variations\win32_development_il2cpp" --avoid-dynamic-library-copy --profiler-report --map-file-parser="D:/Program Files/Unity/Hub/2020.1.3f1/Editor/Data/Tools/MapFileParser/MapFileParser.exe" --directory=D:/Projects/TempName/Temp/StagingArea/Data/Managed --generatedcppdir=D:/Projects/TempName/Temp/StagingArea/Data/il2cppOutput

any ideas what’s wrong?

Regarding that error message:

Workaround: Do a full rebuild or delete the PCH files to force the compiler to recreate them. (src)

supervelly · September 18, 2020, 8:42am

thanks
Although deleted all PCH files didn’t work.
what worked for me was deleting the entire Library/il2cpp_cache folder

Deleting the entire Library/il2cpp_cache folder also worked for me.

Deleting the compiler-mentioned PCH file didn’t. The compiler said it couldn’t find it once I deleted it. Not being able to build was correlated in time (though maybe not causally related) with upgrading Visual Studio.

Thanks for this. I got this error after upgrading to Unity.Entities 0.17. Deleting that il2cpp_cache folder worked for me too.

Heya QA, can you catch this error to send us some in-Unity guidance, mates?

Show us a popup with some options. “Delete cache and try again?”

This one was driving me crazy for hours, even reinstalled Unity 2020 LT
“Deleting the entire Library/il2cpp_cache folder also worked for me” …and so for me.
Thanks

I also had this after a Visual Studio update (applied when closing) and “Deleting the entire Library/il2cpp_cache folder also worked for me”
