Failed to build on MSYS2 MINGW64

[ghost]

Please have a look. There are too many errors so I can't post it here. Thank you.

Hi, I was just able to try compiling with MSYS2 in a long while, and I am running into problem compiling LuaJIT.

Are your error related to LuaJIT or the engine itself ?

Actually they are not errors but warnings. There are too many warning and as ninja by default does parallel builds so I mistake them as full of errors. Indeed there is only one error:

This looks like an include problem. Can you try including <functional> in ecs.h?
