基于 linux-3.0.3、binutils-2.21.1、glibc-2.13、glibc-ports-2.13、gcc-4.6.1、gmp-5.0.2、mpfr-3.0.1、mpc-0.9 构建。
1.创建宿主机编译环境
# apt-get install build-essential libncurses5-dev
创建setbuildenv.sh脚本
setbuildenv.sh
+--------------setbuildenv.sh-----------------+
- #!/bin/sh
- export PRJROOT=/home/mini/arm
- export TARGET=arm-linux
- export PREFIX=${PRJROOT}/tools
- export TARGET_PREFIX=${PREFIX}/${TARGET}
- export PATH=${PREFIX}/bin:${PATH}
+--------------------------------------------------+
$ source setbuildenv.sh
$ cd
$ mkdir arm
$ cd ${PRJROOT}
$ mkdir build-tools tools kernel
$ cd ${PRJROOT}/build-tools
$ mkdir build-binutils build-boot-gcc build-gcc build-glibc build-glibc-headers
$ cd ${PRJROOT}/tools
$ mkdir arm-linux
2.安装内核头文件
$ cd ${PRJROOT}/kernel
$ wget
$ tar xvf linux-3.0.3.tar.gz
$ cd linux-3.0.3
$ cp arch/arm/configs/s3c2410_defconfig ./.config
$ make ARCH=arm CROSS_COMPILE=arm-linux- menuconfig
$ make ARCH=arm CROSS_COMPILE=arm-linux-
$ mkdir -p ${TARGET_PREFIX}/include
$ cp -r include/linux/ ${TARGET_PREFIX}/include
$ cp -r include/asm-generic/ ${TARGET_PREFIX}/include
$ cp -r arch/arm/include/asm/ ${TARGET_PREFIX}/include
################################################################################
$ make ARCH=arm CROSS_COMPILE=arm-linux-
此步的目的是生成 include/linux/version.h 文件，而不是真正的编译，忽略所有错误。
################################################################################
3.编译 binutils
$ cd ${PRJROOT}/build-tools
$ wget
$ tar xvf binutils-2.21.1.tar.gz
$ cd build-binutils
$ ../binutils-2.21.1/configure --target=${TARGET} --prefix=${PREFIX}
$ make
$ make install
4.安装 glibc 头文件
$ cd ${PRJROOT}/build-tools
$ wget
$ wget
$ tar xvf glibc-2.13.tar.gz
$ tar xvf glibc-ports-2.13.tar.gz
$ mv glibc-ports-2.13 ./glibc-2.13/ports
$ cd build-glibc-headers
$ ../glibc-2.13/configure --host=${TARGET} --prefix="/usr" --enable-add-ons --with-headers=${TARGET_PREFIX}/include
$ make cross-compiling=yes install_root=${TARGET_PREFIX} prefix="" install-headers
################################################################################
错误：
+--------------------------------------------------+
configure: error: GNU libc requires kernel header files from Linux 2.0.10 or later to be installed before configuring.
+--------------------------------------------------+
解决方法：
在安装内核头文件的过程中，在设置好内核配置以后，没有使用相应的命令生成 include/linux/version.h 文件。
$ cd ${PRJROOT}/kernel/linux-3.0.3/
$ make ARCH=arm CROSS_COMPILE=arm-linux-
$ cp -r include/linux/ ${TARGET_PREFIX}/include
$ cp -r include/asm-generic/ ${TARGET_PREFIX}/include
################################################################################
错误：
+--------------------------------------------------+
/usr/bin/install: cannot stat `/home/mini/arm/build-tools/build-glibc-headers/gnu/lib-names.h': No such file or directory
+--------------------------------------------------+
解决方法：
方法一：
$ su -
# aptitude purge mawk
# apt-get install gawk
# exit
$ cd ${PRJROOT}/build-tools/build-glibc-headers
$ ../glibc-2.13/configure --host=${TARGET} --prefix="/usr" --enable-add-ons --with-headers=${TARGET_PREFIX}/include
$ make cross-compiling=yes install_root=${TARGET_PREFIX} prefix="" install-headers
方法二：
$ su -
# apt-get install gawk
# exit
$ cd ${PRJROOT}/build-tools/build-glibc-headers
$ vi config.make
找到如下行：
AWK = mawk
将其修改为：
AWK = gawk
################################################################################
5.安装 gcc 引导编译器
$ cd ${PRJROOT}/build-tools
$ wget
$ wget
$ wget
http://www.mpfr.org/mpfr-current/mpfr-3.0.1.tar.gz
$ wget
$ tar xvf gcc-4.6.1.tar.gz
$ tar xvf gmp-5.0.2.tar.gz
$ tar xvf mpfr-3.0.1.tar.gz
$ tar xvf mpc-0.9.tar.gz
$ mv gmp-5.0.2 ./gcc-4.6.1/gmp
$ mv mpfr-3.0.1 ./gcc-4.6.1/mpfr
$ mv mpc-0.9 ./gcc-4.6.1/mpc
$ cd build-boot-gcc
$ mkdir -p ${TARGET_PREFIX}/include/gnu
$ touch ${TARGET_PREFIX}/include/gnu/stubs.h
$ ../gcc-4.6.1/configure --target=${TARGET} --prefix=${PREFIX}
--disable-shared --without-headers --with-newlib --enable-languages=c
$ make all-gcc all-target-libgcc
$ make install-gcc install-target-libgcc
################################################################################
错误：
+--------------------------------------------------+
../../../gcc-4.6.1/libgcc/../gcc/gthr-posix.h:41:21: fatal error: pthread.h: No such file or directory
+--------------------------------------------------+
解决方法：
如果没有安装 glibc 头文件，就开始安装 gcc 引导编译器，需要在 configure 后面加上 --disable-threads 选项。
$ cd ${PRJROOT}/build-tools/build-boot-gcc
$ ../gcc-4.6.1/configure --target=${TARGET} --prefix=${PREFIX}
--disable-shared --disable-threads --without-headers --with-newlib
--enable-languages=c
