< 工控機 (AMD LX處理器平臺, 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平臺的不同~
修改Makefile,
164行改成CROSS_COMPILE ?= 空
189行改成ARCH ?= i386
#如果是arm平臺,CROSS_COMPILE ?= arm-linux-, ARCH ?= arm,
這裏暫用默認設置, 不修改Makefile, 執行make menuconfig,進入配置界面,
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的界面, 執行:
make
make install
生成busybox/_install文件夾;
(二)配置並編譯Kernel:
解壓內核源碼: tar xvzf linux-2.6.32.2.tar.gz
修改Makefile: vi Makefile
在Vi中輸入/,進入搜索,再輸入CROSS_COMPILE,找到
export KBUILD_BUILDHOST := $(SUBARCH)
ARCH ?= $(SUBARCH)
CROSS_COMPILE ?=
修改爲:
export KBUILD_BUILDHOST := $(SUBARCH)
ARCH ?= x86
CROSS_COMPILE ?=
如果目標機是arm平臺,並且編譯器前綴是arm-linux-,則:
export KBUILD_BUILDHOST := $(SUBARCH)
ARCH ?= arm
CROSS_COMPILE ?= arm-linux-
然後執行make menuconfig
