嵌入式linux-arm穿插编译东西链的构建

第一步：首要下载如下源文件
binutils-2.16.tar.gz,gcc-3.4.4.tar.bz2,t-linux.diff,glibc-2.3.5.tar.gz,glibc-linuxthreads-2.3.5.tar.gz,ioperm.c.diff,linux-2.6.11.12tar.gz而且把一切的源文件放入/home/zmj/usr/arm/src文件夹中，其间zmj是用户名。并把如下脚本，写入一个文件，例如文件名为buildchain.sh，并把该文件放入usr目录下。
第二步：运转buildchain.sh脚本即可。其间第七步是不需要的，将来自己编译内核的时分还要重新配置，故能够删去。
#!/bin/bash

# Setup

PREFIX=/home/zmj/usr/arm
TARGET=arm-unknown-linux-gnu
SYSROOT=${PREFIX}/sysroot
export ARCH=arm
export CROSS_COMPILE=${TARGET}-
export PATH=$PATH:${PREFIX}/bin
mkdir -p ${PREFIX}/src

## Get the sources
#
#cd ${PREFIX}/src
#tar xvfz binutils-2.16.tar.gz
#mkdir -p BUILD/binutils-2.16
#cd BUILD/binutils-2.16
# ../../binutils-2.16/configure –prefix=${PREFIX} –target=${TARGET} –with-sysroot=${SYSROOT} 2>&1 | tee configure.out
#make 2>&1 | tee make.out
#make install 2>&1 | tee -a make.out
#
# Linux Kernel Headers

#cd ${PREFIX}/src
#tar xvfz linux-2.6.11.12.tar.gz
#ln -s linux-2.6.11.12 linux
#cd linux
#make ARCH=arm CROSS_COMPILE=${CROSS_COMPILE} menuconfig
#make include/linux/version.h
#mkdir -p ${SYSROOT}/usr/include
#cp -a ${PREFIX}/src/linux/include/linux ${SYSROOT}/usr/include/linux

## Glibc headers
#
#cd ${PREFIX}/src
##tar xvfz glibc-2.3.5.tar.gz
##patch -d glibc-2.3.5 -p1 #cd glibc-2.3.5
##tar xvfj ../glibc-linuxthreads-2.3.5.tar.gz
#cd ..
#mkdir BUILD/glibc-2.3.5-headers

#touch ${SYSROOT}/usr/include/gnu/stubs.h
#touch ${SYSROOT}/usr/include/bits/stdio_lim.h
#
# Step 4: stage 1 gcc
#
#cd ${PREFIX}/src
#bunzip2 -c gcc-3.4.4.tar.bz2 | tar xvf –
#patch -d gcc-3.4.4 -p1 < flow.c.diff

#make 2>&1 | tee make.out
#make install 2>&1 | tee -a make.out
#
# Step 5: glibc

#cd ${PREFIX}/src
#mkdir BUILD/glibc-2.3.5
#cd BUILD/glibc-2.3.5
#BUILD_CC=gcc CC=${CROSS_COMPILE}gcc AR=${CROSS_COMPILE}ar RANLIB=${CROSS_COMPILE}ranlib AS=${CROSS_COMPILE}as LD=${CROSS_COMPILE}ld ../../glibc-2.3.5/configure –prefix=/usr –build=i686-pc-linux-gnu–host=arm-unknown-linux-gnu –target=arm-unknown-linux-gnu –without-__thread –enable-add-ons=linuxthreads –with-headers=${SYSROOT}/usr/include 2>&1 | tee configure.out
#
#make 2>&1 | tee make.out
#make install_root=${SYSROOT} install

# Step 6: stage 2 gcc

#cd ${PREFIX}/src
#mkdir BUILD/gcc-3.4.4
#cd BUILD/gcc-3.4.4
#../../gcc-3.4.4/configure –prefix=${PREFIX} –target=${TARGET} –enable-languages=c,c++ –with-sysroot=${SYSROOT} 2>&1 | tee configure.out
#make 2>&1 | tee make.out
#make install 2>&1 | tee -a make.out
#cd ../..

# Step 7: Linux kernel

cd ${PREFIX}/src/linux
make zImage
make modules
make INSTALL_MOD_PATH=${SYSROOT} modules_install

留意：文中的大部分#号是自己最初为了分步编译过失便利而屏蔽掉的部分。自己编译的时分能够去掉。趁便说一下我是在suse环境下树立这个穿插编译环境的，内核是2.6以上的版别，其间—build=i686-pc-linux-gnu。
几个简略的指令：：set nu显现文本行号。：1，5s/^/#/g能够在文本的1~5行增加一个#号，也即屏蔽掉这几行。1，5s/^#//g去掉文本1~5行文本最初的#号。

第三步测验程序Helloworld.c

#include《stdio.h》
int main( )
{
printf(“Hello ,world!\n”);
return 0;
}
能够在脚本中/etc/bash.bashrc中写入环境变量，也能够直接写如下：
export PATH=/home/zmj/usr/arm/arm/bin:$PATH其间bin中寄存的是自己穿插编译器的途径。
cd ..到helloworld.c的目录。# arm-unknown-linux-gnu-gcc helloworld.c结束！
