arm linux kernel编译问题总结
1 make menuconfig报错
guang@guang-kylin:~/Develop/linux-stable$ make menuconfig
HOSTCC scripts/basic/fixdep
* Unable to find the ncurses libraries or the
* required header files.
* ‘make menuconfig’ requires the ncurses libraries.
* Install ncurses (ncurses-devel or libncurses-dev
* depending on your distribution) and try again.
scripts/kconfig/Makefile:219: recipe for target ‘scripts/kconfig/dochecklxdialog’ failed
make[1]: * [scripts/kconfig/dochecklxdialog] Error 1
Makefile:528: recipe for target ‘menuconfig’ failed
make: * [menuconfig] Error 2
guang@guang-kylin:~/Develop/linux-stable$
解决，安装ncurses：
sudo apt install ncurses-dev
3 busybox执行 make menuconfig报错
guang@guang-ubuntu:~/Develop/busybox$ make menuconfig
HOSTCC scripts/basic/fixdep
HOSTCC scripts/basic/split-include

compilation terminated.
scripts/Makefile.host:120: recipe for target ‘scripts/kconfig/lxdialog/checklist.o’ failed
make[2]: * [scripts/kconfig/lxdialog/checklist.o] Error 1
/home/guang/Develop/busybox/scripts/kconfig/Makefile:14: recipe for target ‘menuconfig’ failed
make[1]: * [menuconfig] Error 2
Makefile:443: recipe for target ‘menuconfig’ failed
make: * [menuconfig] Error 2
解决：
sudo apt-get install libncurses5-dev libncursesw5-dev
make menuconfig执行效果如下
4 开发板启动过程中报：can’t run ‘/etc/init.d/rcS’: Permission denied
解决：增加rcS可执行权限
guang@arm-vexpress:/ # cd etc/init.d/
guang@arm-vexpress:/etc/init.d # ls
rcS
guang@arm-vexpress:/etc/init.d # ls -al
total 3
drwxr-xr-x 2 0 0 1024 Jun 11 18:26 .
drwxr-xr-x 3 0 0 1024 Jun 11 18:26 ..
-rw-r–r– 1 0 0 328 Jun 11 18:26 rcS
guang@arm-vexpress:/etc/init.d # chmod -R 777 rcS
guang@arm-vexpress:/etc/init.d # ls -al

drwxr-xr-x 2 0 0 1024 Jun 11 18:26 .
drwxr-xr-x 3 0 0 1024 Jun 11 18:26 ..
-rwxrwxrwx 1 0 0 328 Jun 11 18:26 rcS
5 无法重启开发板，报
guang@arm-vexpress:/etc/init.d # reboot
reboot: can’t open ‘/proc’: No such file or directory
VFS: Mounted root (ext3 filesystem) on device 179:0.
Freeing unused kernel memory: 1024K
random: crng init done
mount: mounting proc on /proc failed: No such file or directory
mount: mounting tmpfs on /tmp failed: No such file or directory

Welcome to arm vexpress-a9 board
can’t open /dev/console: No such file or directory
can’t open /dev/console: No such file or directory
can’t open /dev/console: No such file or directory
can’t open /dev/console: No such file or directory
can’t open /dev/console: No such file or directory
can’t open /dev/console: No such file or directory
解决：排查了一下，是制作完善rootfs的时候，创建了etc目录，而根目录下对应的proc、mnt、tmp、sys等文件夹忘记创建了，创建了就OK，新增如下文件
效果如下
6 make编译ko文件报错
guang@guang-ubuntu:~/Develop/trainning/ko_file/20180611$ make
make -C /home/guang/Develop/linux-stable M=/home/guang/Develop/trainning/ko_file/20180611 modules
make[1]: Entering directory ‘/home/guang/Develop/linux-stable’
Building modules, stage 2.
MODPOST 1 modules
/bin/sh: 1: scripts/mod/modpost: not found
scripts/Makefile.modpost:92: recipe for target ‘__modpost’ failed
make[2]: * [__modpost] Error 127
Makefile:1576: recipe for target ‘modules’ failed
make[1]: * [modules] Error 2
make[1]: Leaving directory ‘/home/guang/Develop/linux-stable’
Makefile:17: recipe for target ‘default’ failed
make: * [default] Error 2
解决：如下的库可以解决上面类似的大多数问题
sudo apt-get install bison
sudo apt-get install flex
7 make menuconfig报错：
guang@guang-kylin:~/Develop/linux-stable$ make clear
HOSTCC scripts/basic/fixdep
HOSTCC scripts/kconfig/conf.o
YACC scripts/kconfig/zconf.tab.c
/bin/sh: 1: bison: not found

Makefile:528: recipe for target ‘syncconfig’ failed
make[1]: * [syncconfig] Error 2
make: * No rule to make target ‘clear’. Stop.
guang@guang-kylin:~/Develop/linux-stable$
解决：
sudo apt-get install bison
sudo apt-get install flex
8 刚下载完成的linux kernel，make clear失败，make clean成功了，还没来得及分析，记录一下：
guang@guang-kylin:~/Develop/linux-stable$ make clear

HOSTCC scripts/kconfig/zconf.tab.o
HOSTLD scripts/kconfig/conf
scripts/kconfig/conf –syncconfig Kconfig
* Configuration file “.config” not found!
* Please run some configurator (e.g. “make oldconfig” or
* “make menuconfig” or “make xconfig”).
