what's your lua version?

[Ashvith10]

@waruqi I am using Lua v5.4.8.

It should exists if LUA_COMPAT_5_3 is defined.

https://github.com/xmake-io/xmake/blob/3dd5c00c62dcd51ded121a9a0bdb524739fd0bec/core/xmake.sh#L86

#if defined(LUA_COMPAT_5_3)	/* { */

#define lua_objlen(L,i)		lua_rawlen(L, (i)) <--------------------------------------

#endif				/* } */

you can run make VERBOSE=1 to check verbose flags.
