• 1. 配置环境

sudo apt-get install graphviz;sudo apt-get install cflow将 tree2dotx 放入 ~/binsource ~/.profile

• 2. 运行脚本生成 .svg 图

#在你感兴趣的目录下运行,最好不是linux 顶层目录下.mkdir ../outgrep -E "EXPORT_SYMBOL|EXPORT_SYMBOL_GPL" * -nr --exclude=${
   0##*/}  > ../out/log.EXPORT_SYMBOL_origingrep -E "EXPORT_SYMBOL|EXPORT_SYMBOL_GPL" * -nr --exclude=${

• 3. 根据Kconfig Makefile .svg图分析
