\[arm@localhost tchain3.4.4\]\#cd $\{KERNEL\} \[arm@localhost kernel\]\#tar xvfz linux2.6.14.1.tar.gz \[arm@localhost kernel\]\#cd linux2.6.14.1

\[arm@localhost linux2.6.14.1\]\#make ARCH=arm menuconfig \[arm@localhost linux2.6.14.1\]\#make

复制内核头文件

\[arm@localhost kernel\]\#su root

\[root@localhost kernel\]\#mkdir p $\{SYSROOT\}/usr/include

\[root@localhost kernel\]\#cp a include/linux $\{SYSROOT\}/usr/include/linux \[root@localhost kernel\]\#cp a include/asmi386 $\{SYSROOT\}/usr/include/asm \[root@localhost kernel\]\#cp a include/asmgeneric $\{SYSROOT\}/usr/include/asmgeneric \[root@localhost kernel\]\#exit

\[arm@localhost kernel\]\#

译编 **glibc** 头文件

\[arm@localhost kernel\]\#cd $\{SRC\}

\[arm@localhost chain3.4.4\]\#tar xvfz glibc2.3.5.tar.gz \[arm@localhost chain3.4.4\]\#patch d glibc2.3.5 p1 < ioperm.c.diff \[arm@localhost glibc2.3.5\]\#cd glibc2.3.5

\[arm@localhost glibc2.3.5\]\#tar xvfz ../glibclinuxthreads2.3.5.tar.gz \[arm@localhost chain3.4.4\]\#cd ..

\[arm@localhost chain3.4.4\]\#mkdir BUILD/glibc2.3.5headers \[arm@localhost chain3.4.4\]\#cd BUILD/glibc2.3.5headers

\[arm@localhost glibc2.3.5headers\]\#../../glibc2.3.5/configure prefix=/usr host=$\{TARGET\} \\

enableaddons=linuxthreads –withheaders=$\{SYSROOT\}/usr/include \[arm@localhost glibc2.3.5headers\]\#su root

\[root@localhost glibc2.3.5headers\]\#make crosscompiling=yes install\_root=$\{SYSROOT\} installheaders \[root@localhost glibc2.3.5headers\]\#touch $\{SYSROOT\}/usr/include/gnu/stubs.h

\[root@localhost glibc2.3.5headers\]\#touch $\{SYSROOT\}/usr/include/bits/stdio\_lim.h \[root@localhost glibc2.3.5headers\]\#exit

\[arm@localhost glibc2.3.5headers\]\#

注意: prefix=/usr :是 gcc 寻找库的搜索路径。

编译 **gcc** 第一阶段

\[arm@localhost glibc2.3.5headers\]\#cd $\{SRC\} \[arm@localhost chain3.4.4\]\#tar xjvf gcc3.4.4.tar.bz2 \[arm@localhost chain3.4.4\]\#patch d gcc3.4.4 p1 < flow.c.diff \[arm@localhost chain3.4.4\]\#patch d gcc3.4.4 p1 < tlinux.diff \[arm@localhost chain3.4.4\]\#mkdir p BUILD/gcc3.4.4stage1 \[arm@localhost chain3.4.4\]\#cd BUILD/gcc3.4.4stage1

\[arm@localhost gcc3.4.4stage1\]\#../../gcc3.4.4/configure prefix=$\{PREFIX\} target=$\{TARGET\} \\

enablelanguages=c withsysroot=$\{SYSROOT\}

注意：不能加上"disableshared"选项。 \[arm@localhost gcc3.4.4stage1\]\#make allgcc \[arm@localhost gcc3.4.4stage1\]\#su root \[root@localhost gcc3.4.4stage1\]\#make installgcc \[root@localhost gcc3.4.4stage1\]\#exit \[arm@localhost gcc3.4.4stage1\]\#

编译完整的 **glibc**

\[arm@localhost gcc3.4.4stage1\] \#cd $\{SRC\} \[arm@localhost tchain3.4.4\]\#mkdir BUILD/glibc2.3.5 \[arm@localhost tchain3.4.4\]\#cd BUILD/glibc2.3.5

\[arm@localhost glibc2.3.5\]\#BUILD\_CC=gcc CC=$\{CROSS\_COMPILE\}gcc AR=$\{CROSS\_COMPILE\}ar \\ RANLIB=$\{CROSS\_COMPILE\}ranlib AS=$\{CROSS\_COMPILE\}as LD=$\{CROSS\_COMPILE\}ld \\

../../glibc2.3.5/configure prefix=/usr build=i386redhatlinux host=armunknownlinuxgnu \\

target=armunknownlinuxgnu without    thread enableaddons=linuxthreads \\

withheaders=$\{SYSROOT\}/usr/include

说明：

prefix:                            指定安装路径。

target：           指定目标平台。

host:                               指定当前平台。

build:                              指定编译平台。

withsysroot:                 用于指定编译所需要的头文件，及链接库。

enableaddons:           加入其它的库，如线程库等。

enablelanguages:       指定 gcc 所支持的语言。
