I tried to compile Godot on my raspberry pi 3 B+ with this post: https://www.reddit.com/r/godot/comments/af1cji/compiling_godot_31_for_raspberry_pi/. I get this error:
./core/math/random_pcg.h:44:37: warning: integer literal is too large to be
represented in type 'long' and is subject to undefined behavior under
C++98, interpreting as 'unsigned long'; this literal will have type
'long long' in C++11 onwards [-Wc++11-compat]
static const uint64t RANDOMMAX = 4294967295;
(The arrow points toward the 4)
What to do?
