Error using luarocks installation #54
Description
lua_cjson.c: In function ‘json_append_data’:
lua_cjson.c:743:19: warning: implicit declaration of function ‘lua_objlen’ [-Wimplicit-function-declaration]
len = lua_objlen(l, -1);
^~~~~~~~~~
I'm using lua 5.3, and according to the manual lua_objlen is a thing, so I don't see why this would error, but it does

Check how your Lua installation was built. lua_objlen is only available if you compile Lua with certain compatibility flags: https://www.lua.org/source/5.3/luaconf.h.html
It was renamed to lua_rawlen in 5.2.
You need to rebuild with -DLUA_COMPAT_5_1

@ignacio Thanks for the pointer! I'll be sure to try that when I get home, If it works I'll make sure to report back and close this issue.
