[3.0 Alpha] Compile Error: 'JSON::Token::value' uses undefined class 'Variant'

Question

Hello! I was doing alright compiling 3.0 to use the new features despite that it could crash on me at any time, when suddenly the compile doesn't work anymore and renders out this error result:

godot\core/io/json.h(62): error C2079: 'JSON::Token::value' uses undefined class 'Variant'

scons: *** [modules\gdnative\godot\dictionary.windows.tools.64.obj] Error 2
scons: building terminated because of errors.

Any idea on what is causing this error in the compiler?

Answer 1

Open the file godot/core/io/json.h
Change the line 33 from #include "variant.h" to this #include "../variant.h" and it should be compiled successfully.
