You will need to install some version of Visual Studio with the C++ compiler workload, as mentioned in the error message.

3

I resolved the problem by installing the windows 10 sdk through visual studio.

4

It looks like this is the error message which suggests the problem:
clang++.exe: error: no such file or directory: ‘C:\Users\Vladim?r Dubeck?\Desktop\Geometry leap - kopie\Library\il2cpp_android_armeabi-v7a\il2cpp_cache\AC9A2E9056678649598B692E5353E9B3.o’
I suspect those ‘?’ characters that are now not phase of the ASCII character set. I suppose that the Android NDK has hassle with these characters. I would advocate locating your Unity task in a course which has solely ASCII characters. That would possibly work.

Yeah this whole message is a bit of a poor experience when trying to build to il2cpp…
I have VS2019 installed and I installed some C++ component and the windows SDK, still get same issue - edit: eventually fixed by installing all of C++/windows option in VS 2019

  • why is VS2019 not mentioned? (2018 LTS)
  • why no 1-click solution to install the relevant components?
  • why such obtuse console error until you drill down into it?

If you install Unity and choose to install “Visual Studio” component, it will install all the components needed for the build to succeed.

Got any suggestions on how to improve it? I thought the error message was pretty straightforward.

OK I wondered that thanks, I had installed separately.

well I guess I am used to Unity taking the load when building to all platforms, so do not have much knowledge on the individual platforms and even VS setup. So any 1 line summary visible in the console without clicking through would be more explicit, but perhaps I am just too used to how straight forward and easy Unity’s cross platform building is most of the time!

8

For me installing Visual Studio with Unity didn’t help. However installing the Windows 10 SDK like the error said did (before that I first tried installing VS, so maybe both are needed, but my error said it didn’t work because of the missing SDK, even though it also mentioned VS).

Anyway, this is the SDK I installed: Windows SDK - Windows app development | Microsoft Developer

It would be nice that this is installed automatically when installing IL2CPP, I would consider it a bug that it doesn’t, though the given error is clear enough to not really make this a very big problem.
