使用当前平台的 gcc 编译内核头文件

[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。

[arm@localhost glibc­2.3.5]#make [arm@localhost glibc­2.3.5]#su root

[root@localhost glibc­2.3.5]#make install_root=${SYSROOT} install [root@localhost glibc­2.3.5]#exit

[arm@localhost glibc­2.3.5]#
