In addition to C++being difficult to build, combining that with Maya on Windows is even harder. I don't have much experience compiling on windows so maybe a windows user will recognize the fix. A quick look shows that Maya 2020 says it uses Visual Studio C++ 2017. > > On Monday, May 24, 2021 at 1:59:52 PM UTC+2 Marcus Ottosson wrote: > >> Could you post some of those error messages?
