rk3399 pro编译内核

1.从哪里来

• 官方固件没有cdc_acm驱动
• 下载内核源码
• 参考make.sh根据自己的环境执行命令，需要在make rockchip_linux_defconfig之后执行make menuconfig添加cdc_acm驱动编译选项

2.途径何处

• 1.fatal error curses.h no such file or directory
  • sudo apt-get install libncurses5-dev libncursesw5-dev
• 2.gcc: error: unrecognized command line option ‘-mlittle-endian’
  • make时加上交叉编译器CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-gcc
• 3./usr/bin/arm-linux-gnueabihf-gcc gcc:No such file or directory Is your PATH set correctly?
  • 去板子上编译
• 4.bc not found
  • sudo apt install bc
• 5.‘strncat’ specified bound 2 equals source length [-Wstringop-overflow=]
  • Makefile的KBUILD_CFLAGS加入-Wno-stringop-overflow
• 6.板子上没空间了
  • 报错时已有3.6G
