利用busybox, extlinux 在工控機CompactFlash(CF卡)上構建Linux系統(下)

< 工控機 (AMD LX處理器平台, 非ARM) Linux kernel & Busybox 編譯選項配置 >

 

(一) 配置並編譯Busybox:

 

說明, 此次編譯的目標機不是arm板, 而是工控機(研華3355), CPU是AMD low power LX800/500 MHz and LX600/366 MHz Processor,

so~, 注意與傳統的移植arm平台的不同~

 修改Makefile,
       164行改成CROSS_COMPILE ?= 空
       189行改成ARCH ?= i386
       #如果是arm平台,CROSS_COMPILE ?= arm-linux-, ARCH ?= arm,

這裡暫用預設設定, 不修改Makefile, 執行make menuconfig,進入配置介面,

 

General Configuration---> 
 [*] Show verbose applet usage messages 
 [*] Store applet usage messages in compressed form 
 [*] Support –install [-s] to install applet links at runtime 
 [*] Enable locale support(system needs locale for this to work) 
 [*] Support for –long-options 
 [*] Use the devpts filesystem for unix98 PTYs 
 [*] Support writing pidfiles 
 [*] Runtime SUID/SGID configuration via /etc/busybox.config 
 [*]  Suppress warning message if /etc/busybox.conf is not readable 
 
Build Options---> 
 [*] Build BusyBox as a static binary(no shared libs) 
 [*] Build with Large File Support(for accessing files>2GB) 
 
Installation Options-> 
 []Don’t use /usr 
   Applets links (as soft-links) ---> 
 (./_install) BusyBox installation prefix 

 

Busybox Library Tuning ---> 
 (6)Minimum password legth 
 (2)MD5:Trade Bytes for Speed 
 [*]Fsater /proc scanning code(+100bytes) 
 [*]Command line editing 
 (1024)Maximum length of input 
 [*] vi-style line editing commands 
 (15) History size 
 [*] History saving 
 [*] Tab completion 
 [*]Fancy shell prompts 
 (4) Copy buffer size ,in kilobytes 
 [*]Use ioctl names rather than hex values in error mess
 [*]Support infiniband HW 
 
(2)、Linux Module Utilities---> 
  (/lib/modules)Default directory containing modules 
(modules.dep)Default name of modules.dep
[ ] Simplified modutils  
[*] insmod 
[*] rmmod 
[*] lsmod 
[*] modprobe 
-----options common to multiple modutils 
[ ] support version 2.2/2.4 Linux kernels 
[*]Support tainted module checking with new kernels 
[*]Support for module .aliases file 
[*] support for modules.symbols file 

 

退出make menuconfig的介面, 執行:
make
make install

產生busybox/_install檔案夾;

 

 

(二)配置並編譯Kernel:

 

  解壓核心源碼: tar xvzf linux-2.6.32.2.tar.gz
 修改Makefile: vi Makefile
在Vi中輸入/,進入搜尋,再輸入CROSS_COMPILE,找到
  export KBUILD_BUILDHOST := $(SUBARCH)
  ARCH            ?= $(SUBARCH)
  CROSS_COMPILE   ?=
 
修改為:
  export KBUILD_BUILDHOST := $(SUBARCH)
  ARCH  ?= x86
  CROSS_COMPILE ?=

如果目標機是arm平台,並且編譯器首碼是arm-linux-,則:
  export KBUILD_BUILDHOST := $(SUBARCH)
  ARCH  ?= arm
  CROSS_COMPILE ?= arm-linux-

然後執行make menuconfig
