原文地址:编译linaro-gcc工具链 作者:jimgle

关于linaro参见其官网www.linaro.org
gcc-linara源码可以从这个网址下载 http://launchpad.net/gcc-linaro/+milestone/4.8-2013.10
gcc的编译依赖于几个库,GMP,MPFR,MPC,首先需要编译他们,从ftp://gcc.gnu.org/pub/gcc/infrastructure/ 下载这几个库的源代码。
1. 编译GMP  ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-4.3.2.tar.bz2
解压后使用标准的GNU源码编译方法
./configure  --prefix=/home/jqzeng/tools/gmp
make
make install
--host指定的是编译所用主机类型
2. 编译MPFR  ftp://gcc.gnu.org/pub/gcc/infrastructure/mpfr-2.4.2.tar.bz2
./configure  --prefix=/home/jqzeng/tools/mpfr --with-gmp=/home/jqzeng/tools/gmp
make && make install
3.编译MPC  ftp://gcc.gnu.org/pub/gcc/infrastructure/mpc-0.8.1.tar.gz
./configure --prefix=/home/jqzeng/tools/mpc --with-gmp=/home/jqzeng/tools/gmp --with-mpfr=/home/jqzeng/tools/mpfr
make && make install
4.编译isl 下载地址 http://isl.gforge.inria.fr/isl-0.12.tar.gz
./configure --prefix=/home/jqzeng/tools/isl --with-gmp-prefix=/home/jqzeng/tools/gmp
make && make install
5.编译cloog  下载地址 http://www.bastoul.net/cloog/pages/download/count.php3?url=./cloog-0.18.1.tar.gz
./configure  --prefix=/home/jqzeng/tools/cloog --with-gmp-prefix=/home/jqzeng/tools/gmp
make && make install
 ./configure --prefix=/home/jqzeng/tools/libelf
make && make install
7.编译binutils http://releases.linaro.org/13.10/components/toolchain/binutils-linaro
./configure --prefix=/usr/local/linaro-gcc --with-sysroot=/usr/local/arm-linux/arm-linux-gnueabi/libc --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=arm-linux-gnueabi --with-gmp=/home/jqzeng/tools/gmp --with-isl=/home/jqzeng/tools/isl  --with-mpfr=/home/jqzeng/tools/mpfr --with-mpc=/home/jqzeng/tools/mpc
make 
sudo make install
加上--with-sysroot是很重要的,否则编译gcc的时候会出现“ld:this linker was not configured to use sysroots”的错误。
8. 安装内核头文件
解压内核并cd到源码目录,执行下面的命令构建sanitized 版本内核头文件。
make ARCH=arm headers_check
 sudo make ARCH=arm INSTALL_HDR_PATH=/usr/local/arm-linux/arm-linux-gnueabi/libc/usr headers_install
9. 编译c库头文件  eglibc  http://releases.linaro.org/13.10/components/toolchain/eglibc-linaro/eglibc-linaro-2.18-2013.10.tar.bz2
mkdir build

CC=gcc ../configure  --prefix=/usr/local/arm-linux/arm-linux-gnueabi/libc/usr --build=x86_64-linux-gnu --host=arm-linux-gnueabi --with-header=/usr/local/arm-linux/arm-linux-gnueabi/libc/usr/include 
sudo make install-headers
注意这里设置的--host是目标板,与其他地方的不一样。
内核头文件和C库头文件放在sysroot下,消除缺少头文件的问题“The directory that should contain system headers does not exist” 
10.编译用于编译glibc的gcc
解压gcc-linara,cd到源码目录
mkdir build
cd build
../gcc-linaro-4.8-2013.10/configure --prefix=/usr/local/arm-linux --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=arm-linux-gnueabi --with-gmp=/home/jqzeng/tools/gmp
 --with-mpfr=/home/jqzeng/tools/mpfr --with-mpc=/home/jqzeng/tools/mpc --with-isl=/home/jqzeng/tools/isl --with-cloog=/home/jqzeng/tools/cloog
--with-libelf=/home/jqzeng/tools/libelf --enable-languages=c,c++,fortran --enable-multilib --with-arch=armv7-a --with-tune=cortex-a9 --with-fpu=vfpv3-d16 --with-float=hard
--enable-__cxa_atexit --enable-libmudflap --enable-libgomp --enable-libssp --enable-threads=posix --disable-libstdcxx-pch --enable-linker-build-id --enable-gold  --enable-c99
--enable-long-long --with-mode=thumb --with-sysroot=/usr/local/linaro-gcc/arm-linux-gnueabi/libc --with-local-prefix=/usr/local/linaro-gcc/arm-linux-gnueabi/libc
make -j4


到这里配置出错了
checking for version 0.10 of ISL... no
checking for version 0.11 of ISL... no
checking for version 0.12 of ISL... no
configure: error: Unable to find a usable ISL.  See config.log for details.
打开config.log
configure:5857: checking for version 0.10 of ISL

configure:5924: $? = 0
configure:5924: ./conftest
好吧,是加载动态库的时候出问题了。
 sudo vim /etc/ld.so.conf.d/ld.isl.so.conf
将isl的lib库的绝对路径写入ld.isl.so.conf文件中 /home/jqzeng/tools/isl/lib
顺便将tools目录下的其他动态库的路径都加上
执行下面的命令重建/etc/ld.so.cache
sudo ldconfig
重新来一遍配置gcc-linara。
执行make,喝杯咖啡歇会,这是个漫长的过程。
sudo make install

11 编译eglibc
 CC=arm-linux-gnueabi-gcc ../configure  --prefix=/usr/local/arm-linux/arm-linux-gnueabi/libc/ --build=x86_64-linux-gnu --host=arm-linux-gnueabi
--with-header=/usr/local/arm-linux/arm-linux-gnueabi/libc/usr/include --enable-add-ons --with-binutils=/usr/local/arm-linux/bin --enable-shared libc_cv_forced_unwind=yes
libc_cv_c_cleanup=yes
make 
sudo make install

好吧,现在工具链已经编译完成,下一步是使用该工具链编译uboot和kernel。
