Build Error Relating to IL2CCP When on Android

Unity Engine
,
1

I get this build error whenever I’m building for android, and I have no idea what it means or how to fix it. If somebody could help out I would greatly appreciate it:

The error seems to be this:

Access to the path ‘\?\C:\Users\cafeboy\Desktop\Unity\Practice\Parry_Slash\Library\il2cpp_android_arm64-v8a\il2cpp_cache\linkresult_883AF8FA1F5B9312C39A7AF85E9B1117’ is denied.

It looks like something it trying to use an extended length path or use some special characters in the path. See windows - What does \\?\ mean when prepended to a file path - Stack Overflow for more details.

I’m unsure why that is happening in this case though. Could it have something to do with the way you started the Unity editor?

3

I recently changed the project folder name. Could this be a large factor?

4

That might be the case. I wonder if something is cached in the Library folder with the previous project name. You could try deleting or renaming the Library folder (with the editor closed). Then it will be regenerated.

Deleted the Library folder, then tried to Build. It resulted in this error:

Based on this thread, it looks like that happens when the disk is out of space: Win IO 32 returned 112

Is that the case for your build?
