接前一篇文章：x86 Linux系统下构建交叉编译工具（2）
本文参考以下文章：
建立交叉编译器 for arm （binutils-2.17 gcc-3.4.6 glibc-2.3.6）
特此致谢！
上一回构建了binutils的交叉环境，本回进行引导编译器交的构建。
二、编译构建
2. 引导编译器构建
（1）build-tools目录下创建build-binutils文件夹
进入到cross-compiler/build-tools目录。如下所示：
~$ cd cross-compiler/build-tools/
~/cross-compiler/build-tool$ ls
binutils-2.41 binutils-2.41.tar.xz build-binuitls gcc-13.2.0.tar.xz glibc-2.38.tar.xz
（2）解压glibc源码压缩包
通过tar命令解压glibc源码压缩包。实际命令及结果如下所示（截取部分）：
$ tar xvf glibc-2.38.tar.xz
……

glibc-2.38/wctype/wctype.c
glibc-2.38/wctype/wctype.h
glibc-2.38/wctype/wctype_l.c
$ 解压后glibc-2.38目录内容如下：
$ ls glibc-2.38

（3）下载glibc-linuxthreads源码压缩包
到以下页面下载gibc-linuxthreads源码压缩包：http://ftp.vim.org/ftp/gnu/glibc/
选择glibc-linuxthreads-2.5.tar.bz2，下载并将其放入到~/cross_compiler/build-tools目录。
（4）解压glibc-linuxthreads源码压缩包
进入~/cross-compiler/build-tools目录，通过tar命令解压glibc-linuxthreads源码压缩包。实际命令及结果如下所示：
$ tar xvf glibc-linuxthreads-2.5.tar.bz2 --directory=glibc-2.38

（5）创建并进入build-glibc-headers文件夹
在cross-compiler/build-tools目录下创建build-glibc-headers目录，并进入。如下所示：
~/cross-compiler/build-tools$ mkdir build-glibc-headers
~/cross-compiler/build-tools$ cd build-glibc-headers/
~/cross-compiler/build-tools/build-glibc-headers$
（6）配置
执行configure进行glibc的配置。实际命令及结果如下：

running configure fragment for sysdeps/unix/sysv/linux
checking installed Linux kernel header files... missing or too old!
configure: error: GNU libc requires kernel header files from
Linux 3.2.0 or later to be installed before configuring.
The kernel header files are found usually in /usr/include/asm and
/usr/include/linux; make sure these directories use files from
Linux 3.2.0 or later. This check uses <linux/version.h>, so
make sure that file was built correctly when installing the kernel header
files. To use kernel headers not from /usr/include/linux, use the
configure option --with-headers.
（7）编译
执行make命令进行glibc的编译。实际命令及结果如下：
~/cross-compiler/build-tools/build-glibc-headers$ make cross-compiling=yes install_root=/usr/local/arm/arm-linux/ prefix="" build_directory=../build-glibc-headers install-headers
make: *** 没有规则可制作目标“install-headers”。 停止。
将目录切换到glibc-2.38下，再次运行以上命令：
~/cross-compiler/build-tools/build-glibc-headers$ cd ../glibc-2.38/
~/cross-compiler/build-tools/glibc-2.38$ make cross-compiling=yes install_root=/usr/local/arm/arm-linux/ prefix="" build_directory=../build-glibc-headers install-headers
Makeconfig:43: *** objdir must be defined by the build-directory Makefile。 停止。
存在一定问题，也许是版本问题，也许是其它问题。需要后续深入解决。
