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
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:
1.crosstool-ng的安装
2.安装必要工具包
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
4.为工具链增加新链接
  
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
  
错误与解决

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: 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 …… )
