    首先感谢网上很多前辈的文章，可以少走些弯路。主要参照了下边的文章，在此表示感谢。

从打算亲手制作下交叉工具链，到编译成功，前后折腾了10多个晚上。终于编译成功了，感到很高兴。其中最不顺利的是编译glibc库。

 下边是自己的编译过程，希望为其他也想编译交叉工具链的兄弟，能提供些参考。

 

    一、编译交叉工具链的大致过程是，首先用本机gcc编译binutils，之后用本机gcc编译boot-trap gcc，
接着用编译出来的boot-trap gcc 编译glibc，最后用本机gcc编译完整的交叉gcc。

    二、另外注意配置./configure交叉编译时，用到的三个重要的平台选项：
--build=编译这个软件所使用的平台。如果没有指定,默认值将是'--host'选项的值
--host=该软件运行的平台。如果没有指定,将会运行`config.guess'来检测.
--target=该软件生成目标文件的运行平台。如果没有指定,默认将使用'--host'选项的值
  
     也就是--build=编译平台　--host=运行平台　--target=目标平台
  
   三、需要的源码：binutils-2.19.1.tar.bz2, gcc-4.4.0.tar.bz2, gdb-7.2a.tar.gz, gmp-4.3.0.tar.bz2,  mpfr-2.4.1.tar.bz2,
 linux-2.6.29.tar.bz2,  glibc-2.9.tar.gz,  glibc-ports-2.9.tar.bz2 可以从http://oss.ustc.edu.cn 以及网上下载。

   四、下边是自己的编译过程。

1、bash 文件bashEnv的内容
[yanglu@localhost ~]$ cat bashEnv
#!/bin/sh

export PRJROOT=/home/yanglu/arm
export TARGET=arm-sdutyl-linux-gnueabi
export PREFIX=${PRJROOT}/tools
export TARGET_PREFIX=${PREFIX}/${TARGET}
export PATH=$PREFIX/bin:$PATH

#===========my cmd===============
alias  cdb='cd ${PRJROOT}/build '
alias  cdt='cd ${PRJROOT}/tools'
alias  cds='cd ${PRJROOT}/source'

2、目录结构
/home/yanglu
/home/yanglu/arm
/home/yanglu/arm/build
/home/yanglu/arm/build/gcc
/home/yanglu/arm/build/gdb
/home/yanglu/arm/build/gdbserver
/home/yanglu/arm/build/glibc
/home/yanglu/arm/build/gcc2
/home/yanglu/arm/build/binutils

/home/yanglu/arm/source
/home/yanglu/arm/source/linux-2.6.29
/home/yanglu/arm/source/binutils-2.19.1
/home/yanglu/arm/source/gcc-4.4.0/
/home/yanglu/arm/source/gmp-4.3.0/
/home/yanglu/arm/source/mpfr-2.4.1/
/home/yanglu/arm/source/glibc-2.9
/home/yanglu/arm/source/glibc-ports-2.9
/home/yanglu/arm/source/gdb-7.2

/home/yanglu/arm/tools

3、编译前，首先导入bashEnv文件使环境变量生效
[yanglu@localhost ~]$ source bashEnv

4、编译binutils
[yanglu@localhost]$ pwd
/home/yanglu/arm/build/binutils

[yanglu@localhost]$ ../../source/binutils-2.19.1/configure --target=${TARGET} --prefix=${PREFIX} --disable-nls --disable-werror --disable-multilib  --enable

-shared

[yanglu@localhost ]$make configure-host 
[yanglu@localhost ]$make
[yanglu@localhost ]$make install

5、编译boot-trap gcc (首先将浮点支持的库的源文件移动到gcc目录)
[yanglu@localhost ]$mv ~/arm/source/gmp-4.3.0/  ~/arm/source/gcc-4.4.0/gmp
[yanglu@localhost ]$mv ~/arm/source/mpfr-2.4.1/  ~/arm/source/gcc-4.4.0/mpfr
[yanglu@localhost ]$cdb
[yanglu@localhost ]$cd gcc
[yanglu@localhost gcc]$ pwd
/home/yanglu/arm/build/gcc

[yanglu@localhost gcc]$ ~/arm/source/gcc-4.4.0/configure  --target=${TARGET} --prefix=${PREFIX} --without-headers --with-newlib --with-float=soft \
--with-cpu=arm920t --with-tune=arm9tdmi --with-gnu-as --with-gnu-ld --disable-nls --disable-decimal-float --disable-libgomp \
--disable-multilib --disable-libmudflap --disable-libssp --disable-shared --disable-threads --disable-libmudflap \
--disable-libstdcxx-pch --disable-libffi --enable-languages=c

[yanglu@localhost gcc]$make

[yanglu@localhost gcc]$make install

[yanglu@localhost gcc]$cd /home/yanglu/arm/tools/lib/gcc/arm-sdutyl-linux-gnueabi/4.4.0
[yanglu@localhost gcc]$ln -s libgcc.a libgcc_eh.a

6、配置linux 生成头文件

<1> [yanglu@localhost ]$ cd /home/yanglu/arm/source/linux-2.6.29
<2> [yanglu@localhost linux-2.6.29]$ make ARCH=arm CROSS_COMPILE=${TARGET}- INSTALL_HDR_PATH=${TARGET_PREFIX} menuconfig
     配置后保存退出。
    注： 在弹出的配置中，选择cpu型号（三星SC2440）
        System Type->ARM System Type->/Samsung S3C2440

<3> [yanglu@localhost linux-2.6.29]$make ARCH=arm CROSS_COMPILE=${TARGET}- INSTALL_HDR_PATH=${TARGET_PREFIX}
    执行这步出错后，不用管，主要是为了生成头文件。
 
<3> 检查目录home/yanglu/arm/source/linux-2.6.29/include/linux 下是否生成了version.h 和 autoconf.h，
    若存在，说明生成了正确的头文件

<4>  [yanglu@localhost linux-2.6.29]$ make ARCH=arm CROSS_COMPILE=${TARGET}- INSTALL_HDR_PATH=${TARGET_PREFIX} headers_install
    安装头文件

7、编译glibc
<1>为了使Glibc支持NPTL，需要在Glibc编译目录下建立config.cache文件并写入：
[yanglu@localhost glibc]$ pwd
/home/yanglu/arm/build/glibc

[yanglu@localhost glibc]$cat > config.cache << EOF
libc_cv_forced_unwind=yes
libc_cv_c_cleanup=yes
libc_cv_arm_tls=yes
libc_cv_gnu99_inline=yes
EOF

<2> 添加环境变量
[yanglu@localhost glibc]$ BUILD_CC=gcc \
CC=${TARGET}-gcc \
AR=${TARGET}-ar \
RANLIB=${TARGET}-ranlib \

(注: glibc 用交叉gcc编译，感觉应该是因为glibc是在嵌入式平台上工作的--host=${TARGET}， 而用本机的gcc编译出来的target 目标文件，
  是运行的本机上的。 而交叉gcc编译出来的target目标文件，就是工作在嵌入式平台的。所以编译工具需要用交叉gcc)

<3> 配置
[yanglu@localhost glibc]$ ~/arm/source/glibc-2.9/configure  --host=${TARGET} --target=${TARGET} --prefix="/usr" --with-headers=${TARGET_PREFIX}/include --

with-binutils=${PREFIX}/bin --with-tls --with-__thread --enable-sim --enable-nptl --enable-add-ons --enable-kernel=2.6.29 --disable-profile --without-gd --

without-cvs --cache-file=config.cache

<4> make

<5> make install_root=${TARGET_PREFIX} prefix="" install

<6> 去掉libc.so 中的绝对路径
    vi ${TARGET_PREFIX}/lib/libc.so

   [yanglu@localhost lib]$ cat ${TARGET_PREFIX}/lib/libc.so
/* GNU ld script
   Use the shared library, but some functions are only in
   the static library, so try that secondarily.  */
OUTPUT_FORMAT(elf32-littlearm)
GROUP ( libc.so.6 libc_nonshared.a  AS_NEEDED ( ld-linux.so.3 ) )
[yanglu@localhost lib]$

8、编译full gcc
[yanglu@localhost gcc2]$ pwd
/home/yanglu/arm/build/gcc2

[yanglu@localhost gcc2]$ ~/arm/source/gcc-4.4.0/configure --target=${TARGET} --prefix=${PREFIX} --with-float=soft --with-cpu=arm920t \
--with-tune=arm9tdmi --enable-languages=c,c++ --enable-threads=posix --enable-c99 --enable-long-long \
--enable-shared --enable-__cxa_atexit --enable-nls --disable-libgomp

9、编译gdb
 [yanglu@localhost gdb]$ ~/arm/source/gdb-7.2/configure --target=${TARGET} --prefix=${PREFIX}
 [yanglu@localhost gdb]$ make
 [yanglu@localhost gdb]$ make install

10、 编译gdbserver（因为gdbserver 需要运行在嵌入式开发板上，所以host配置成嵌入式平台。也就需要交叉gcc编译器）
 [yanglu@localhost gdbserver]$ CC=${TARGET}-gcc AR=${TARGET}-ar RANLIB=${TARGET}-ranlib
 [yanglu@localhost gdbserver]$  ~/arm/source/gdb-7.2/gdb/gdbserver/configure --host=${TARGET} --target=${TARGET}
 [yanglu@localhost gdbserver]$  make
 
注：编译gdbserver时如果出现PATH_MAX undeclared错误，在gdb/gdbserver/hostio.c，
   /home/yanglu/arm/source/gdb-7.2/gdb/gdbserver/thread-db.c 文件中增加，#include <linux/limits.h>，原因是宏PATH_MAX在<limits.h>中没有定义，   而是定义在

<linux/limits.h>中

#编译完成之后会在/home/yanglu/arm/build/gdbserver中生成gdbserver


附:文件目录变化
1、安装binutils 之后的目录
