ubuntu 环境编译bsp/linux下demo后执行./luatos 提示找不到sys

[yougaliu007]

如题，在ubuntu环境下载luatOS代码后，编译bsp/linux下代码，执行如下命令，提示找不到sys模块。 luatos可执行文件所在目录 bsp/linux/build

$ ./luatos -i ../main.lua Lua 5.3.6 Copyright (C) 1994-2018 Lua.org, PUC-Rio Enhance by LuatOS E/lua.err ./luatos: E/lua.err ../main.lua:3: module 'sys' not found stack traceback: [C]: in global 'require' ../main.lua:3: in main chunk [C]: in ?

确实，你可以手动把sys.lua复制到当前目录

[yougaliu007]

copy sys.lua and main.lua file to luatos dir, still can not find sys

我觉得是这里导致的问题

需要编译成32位才能兼容

[wendal]

因为内嵌的sys.luac是32位的
