用crosstool-ng建立arm-linux 4.3.2 交叉工具链

2013年10月03日 ⁄ 综合 ⁄ 共 6717字 ⁄ 字号小中大 ⁄ 评论关闭

crosstool-ng是新的用来建立交叉工具链的工具，它是crosstool的替换者.
使用crosstool最多只能编译gcc 4.1.1　glibc 2.x的版本.

而crosstool-ng一直保持着更新,现在最新能够建立 gcc 4.3.2版本 glibc 2.9版本...

在使用低于4.1.1的版本编译2.6.29 kernel时，会出现

include/linux/compiler-gcc4.h:7:3: error: #error Your version of gcc miscompiles the __weak directive

include/linux/compiler-gcc4.h:7
:如下

/* GCC 4.1.[01] miscompiles __weak */
#if __GNUC_MINOR__ == 1 && __GNUC_PATCHLEVEL__ <= 1
# error Your version of gcc miscompiles the __weak directive
#endif

所以使用crosstool-ng建立一个新的工具链(gcc 4.3.2 glibc 2.9)，以支持对最新kernel编绎.

测试环境：

Debian Linux 2.6.18-6-686
Ubuntu Linux 2.6.28-14 (Ubuntu 9.0.4)

1.crosstool-ng的安装

cd /tmp

mkdir crosstool-ng

wget http://ymorin.is-a-geek.org/download/crosstool-ng/crosstool-ng-1.4.1.tar.bz2

tar jxvf crosstool-ng-1.4.1.tar.bz2

cd /tmp/crosstool-ng-1.4.1

./configure --prefix=/opt/crosstool-ng

make

make install

echo "PATH=$PATH:/opt/crosstool-ng/bin" >> ~/.bashrc

source ~/.bashrc

ct-ng help

## ^ ^ 安装成功

2.安装必要工具包

#安装java开发包

sudo apt-get install gcj

#安装cvs

sudo apt-get install cvs

#切换mawk

sudo apt-get install gawk

cd /usr/bin

sudo mv mawk mawk.bak

sudo ln -s gawk mawk

Ubuntu 9.0.4 请先安装下 termcap 库参考本文错误与解决 4.. .

3.crosstool-ng使用范例

本范例记录了使用crosstool-ng编绎arm-unknown-linux-gnueabi工具链的过程

cd /tmp/crosstool-ng

mkdir build_toolchain

cp /opt/crosstool-ng/lib/ct-ng-1.4.1/samples/arm-unknown-linux-gnueabi/crosstool.config .config

mkdir ~/src

vi .config

修改工具链安装路径

CT_PREFIX_DIR="/opt/arm/4.3.2/${CT_TARGET}"

ct-ng build.4(用太多线程，很耗系统资源)

4.为工具链增加新链接

cd /opt/arm/4.3.2/arm-unknown-linux-gnueabi/bin

./autoln.sh

autoln.sh是一个脚本，用来自动链接arm-unknown-linux-gnueabi的工具...

文件名:autoln.sh
拷到要自动建立链接的文件夹使用。

#!/bin/bash

#
# main
#
if [ $# -lt 1 ] ; then
echo "default path: ./"
BIN_PATH=./
else
BIN_PATH=$1
fi
if [ ! -d $1 ] ; then
echo "path error"
exit
fi
cd $BIN_PATH
SRC=`ls | awk '{print $1}'`

for i in $SRC ; do
if [ "$i" != "autoln.sh" ] ; then
      #echo $i
      TARGET=`echo $i | sed 's/arm-unknown-linux-gnueabi/arm-linux/g' `
      echo $TARGET
      ln -s $i $TARGET
fi
done

[ERROR] (elapsed: 36:41.91)

make: *** [build.4] 错误 2

解决:查看build.log

[ALL ] /usr/bin/install: cannot stat `/tmp/crosstool-ng/targets/arm-unknown-linux-gnueabi/build/build-libc-headers/gnu/li
b-names.h': No such file or directory

但在这之前也发生了一个error，但crosstool-ng并没有报错

[ALL ]     mawk: scripts/gen-sorted.awk: line 19: regular expression compile failed (bad class -- [], [^] or [)
[ALL ]     /[^
[ALL ]     mawk: scripts/gen-sorted.awk: line 19: syntax error at or near ]
[ALL ]     mawk: scripts/gen-sorted.awk: line 19: runaway regular expression /, "", subd ...

OK,在gen-sorted.awk第19行，出错，这是一个简单的错误，缺少了转义符

查找一个看有没有类似的　　

cd /tmp/crosstool-ng/targets/src/glibc-cvs-2.9/scripts　

　sed '//^///p' gen-sorted.awk -n

　输出的则是存在语法错误的语句

　可以直接用

　sed -i 's//^////^/////g' gen-sorted.awk

这种方法是不完善的，后面的还是会出现错误。

　网上搜了下，需要用/usr/bin/gawk 替换/usr/bin/mawk，即

sudo apt-get install gawk

cd /usr/bin

sudo mv mawk mawk.bak

sudo ln -s gawk mawk

解决
:
      这个问题我只在ubuntu 9.0.4中遇到过...缺少了termcap 库，但我在源里又没有搜到termcap相关的库（似乎是被其它库替换了，termcap这东西的确很古老)
      cd /tmp
      wget ftp://ftp.gnu.org/gnu/termcap/termcap-1.3.1.tar.gz
      tar zxvf
termcap-1.3.1.tar.gz
      cd termcap-1.3.1
      ./configure --prefix=/usr
      make
      make install
      （又需要从头编译工具链了 …… ）
