x86 Linux系统下构建交叉编译工具（3）

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/wcsmbs/wcstoull_l.c
glibc-2.38/wcsmbs/wcswidth.c

glibc-2.38/wcsmbs/wmemset.c
glibc-2.38/wctype/
glibc-2.38/wctype/Makefile
glibc-2.38/wctype/Versions
glibc-2.38/wctype/bits/
glibc-2.38/wctype/bits/wctype-wchar.h
glibc-2.38/wctype/bug-wctypeh.c
glibc-2.38/wctype/iswctype.c
glibc-2.38/wctype/iswctype_l.c
glibc-2.38/wctype/test_wcfuncs.c
glibc-2.38/wctype/test_wctype.c
glibc-2.38/wctype/towctrans.c
glibc-2.38/wctype/towctrans_l.c
glibc-2.38/wctype/wcfuncs.c
glibc-2.38/wctype/wcfuncs_l.c
glibc-2.38/wctype/wchar-lookup.h
glibc-2.38/wctype/wctrans.c
glibc-2.38/wctype/wctrans_l.c
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：

（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：

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 , 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。
