SCons

SConstruct (SCons) 是跨平台的构建系统，因此在 Windows 和 Linux 上的用法相同。关于 SConstruct 的详细介绍，可查看 SConstruct。

SCons 常用的命令有：

罗列项目： scons –list-def

罗列 SDK 中发布的项目名称。

scons --list-def
scons: Reading SConscript files ...
Built-in configs:

使用项目：scons –apply-def

设置使用某一个项目，可以用项目名称，也可以用项目的索引。

scons --apply-def=2
scons: Reading SConscript files ...
Load config from target\configs\d21x_demo100-nand_rt-thread_helloworld_defconfig

scons --apply-def=d21x_demo100-nand_rt-thread_helloworld_defconfig
scons: Reading SConscript files ...
Load config from target\configs\d21x_demo100-nand_rt-thread_helloworld_defconfig

配置项目：scons –menuconfig
Luban-Lite 使用 menuconfig 界面进行项目的配置工作。
```
scons --menuconfig
```
构建项目：scons
进行项目构建，默认是简洁模式，不会输出编译选项等信息，调试时可以使用 scons –verbose 打印编译器选项等辅助信息。
```
scons
scons: Reading SConscript files ...
>>> Extract toolchain Xuantie-900-gcc-elf-newlib-mingw ...
```
清理项目：scons –clean
清除上一次编译的临时文件。执行该命令后，下一次编译将能保证所有源文件都会被重新编译。
```
scons --clean
scons -c
```

OneStep

OneStep 是 ArtInChip 为了简化 SDK 的使用而开发的一系列易用性命令。

在 Windows 系统中，OneStep 自动集成到 win_cmd.bat 和 win_env.bat 批处理脚本中。
在 Linux 系统中需要加入到当前路径中：sourcetools/onestep.sh

OneStep 命令列表如下：

Luban-Lite SDK OneStep commands:
  hmm|h                     : Get this help.
  lunch          [keyword]  : Start with selected defconfig.e.g. lunch mmc
