2.3.1.2. 使用项目

命令：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=d21x_demo100-nand_baremetal_helloworld_defconfig
scons: Reading SConscript files ...
Load config from target\configs\d21x_demo100-nand_baremetal_helloworld_defconfig

scons --apply-def=8
scons: Reading SConscript files ...
Load config from target\configs\d21x_demo100-nand_baremetal_helloworld_defconfig

2.3.1.3. 配置项目

命令：scons –menuconfig：Luban-Lite 使用 menuconfig 界面进行项目的配置工作

scons --menuconfig
../../_images/lbl-menuconfig.png

2.3.1.4. 构建项目

命令：scons：进行构建，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 ...

2.3.1.5. 清理项目

命令：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

2.3.2. OneStep

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

2.3.2.1. Windows

在 Windows 系统中，OneStep 自动集成到 win_cmd.bat 和 win_env.bat 批处理脚本中

2.3.2.2. Linux

在 Linux 系统中需要加入到当前路径中

source tools/onestep.sh
