IL2CPP build error - Githubissues

murray-walker commented 3 years ago

We're not able to build the latest version due to an IL2CPP issue. There's not much help on the forums for this so thought I'd flag it here.

My colleague and I are getting the same error - We believe we have the correct C++ compilers and Windows 10 SDKs installed in our IDEs.

Here is the error:
