在slackware上编译2.6.0内核

Question

出于纯粹的好奇心,我尝试在我的slackware机器上编译2.6.0内核.

root@darkstar:/home/linux-2.6.0# uname -a
Linux darkstar 2.6.37.6-smp #2 SMP Sat Apr 9 23:39:07 CDT 2011 i686 Intel(R) Core(TM)2 Duo CPU     P8600  @ 2.40GHz GenuineIntel GNU/Linux

当我尝试编译时,我得到: -

root@darkstar:/home/linux-2.6.0# make menuconfig                                                                                         
  HOSTCC  scripts/fixdep
scripts/fixdep.c: In function 'traps':

  HOSTCC  scripts/kconfig/conf.o
  HOSTCC  scripts/kconfig/mconf.o

scripts/kconfig/lkc.h:63:21: note: previous declaration of 'current_menu' was here
make[1]: *** [scripts/kconfig/mconf.o] Error 1
make: *** [menuconfig] Error 2

关于我做错什么的一些暗示？谢谢!

你是如何开始这样做的？

通常,您从kernel.org下载最新的内核,将tarball复制到/ usr/src,然后:

 1. tar -zxvvf linux-2.6.xxxx.tar.gz
 2. ln -nsf linux-2.6.xxxx linux   # ie: Update the "/usr/src/linux" symbolic link to
                                   #   point to the new kernel source directory
 3. make menuconfig                # or make xconfig
 4. make modules                   # Build the kernel modules
 5. make modules_install           # Install the previously built modules for the
                                   #   new kernel
 6. make bzImage                   # Create the boot image

此时,请勿运行make install.大多数导游说这样做,但这是错误的!相反,将新创建的bzImage文件复制到/ boot(即:find -name bzImage /usr/src/linux,然后复制cp到/boot),然后编辑LILO配置文件(编辑/etc/lilo.conf,完成后运行lilo),然后重新启动系统(即:init 6或shutdown -r now),并尝试新的核心.

跳过该make install步骤的重点是因为它会覆盖/替换现有内核.我上面描述的步骤允许您同时安装和运行新内核和现有内核.如果新内核被破坏或您遗漏了一个重要选项,您仍然可以回退到现有的稳定/可用内核而无需启动/恢复CD/DVD.
