[LINUX问答]内核编译

1、make mrproper

root@ubuntu:/boot# cd /usr/src/linux-source-3.5.0/
root@ubuntu:/usr/src/linux-source-3.5.0# make mrproper
  CLEAN   /usr/src/linux-source-3.5.0/debian/
root@ubuntu:/usr/src/linux-source-3.5.0#

 

2、make menuconfig

root@ubuntu:/usr/src/linux-source-3.5.0# make menuconfig
  HOSTCC  scripts/basic/fixdep
  HOSTCC  scripts/kconfig/conf.o
 *** Unable to find the ncurses libraries or the
 *** required header files.
 *** 'make menuconfig' requires the ncurses libraries.
 ***
 *** Install ncurses (ncurses-devel) and try again.
 ***
make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
make: *** [menuconfig] Error 2

注意

Linux下面去编译项目之前，一般常会用make mrproper去先删除之前编译所生成的文件和配置文件，备份文件等，其中，mrproper和distclean，clean之间的区别，Linux内核源码根目录下面的makefile中，有很清晰的解释：
help:
@echo 'Cleaning targets:'
@echo ' clean - Remove most generated files but keep the config and'
@echo ' enough build support to build external modules'
@echo ' mrproper - Remove all generated files + config + various backup files'

@echo ' distclean - mrproper + remove editor backup and patch files'

简单点说

make mrproper命令会删除所有的编译生成文件、内核配置文件(.config文件)和各种备份文件，所以几乎只在第一次执行内核编译前才用这条命令。

make clean命令则是用于删除大多数的编译生成文件，但是会保留内核的配置文件.config，还有足够的编译支持来建立扩展模块。所以你若只想删除前一次编译过程的残留数据，只需执行make clean命令。

总而言之，make mrproper删除的范围比make clean大，实际上，make mrproper在具体执行时第一步就是调用make clean
