本文件用于生成内嵌到固件里的脚本

默认是corelib目录里的全部.lua文件

如需新增或更新, 把.lua文件放入corelib目录, 在当前目录下执行:
luatos_32bit.exe update_inline_libs.lua

相关exe文件可以在 https://gitee.com/openLuat/LuatOS/attach_files 下载

-- 主要配置项, lua分需要区分两种编译环境:
-- lua_Integer的大小, 受 LUA_32BITS控制, 默认是启用
-- size_t 大小, 与平台相关, MCU上通常为32bit
-- 虽然可以两两组成, 但实际情况只有2种,当前:

-- local bittype = "64bit_size32"
local bittype = "32bit"
-- local bittype = "source"

if bittype == "32bit" then
    typename = ""
