按照上述内容check到相应的版本。

3.准备sysroot

可以自己先编译一版android os，只要确保bionic c被编译即可

使用build下的脚本拷贝到sys root下

./build-sysroot.sh build_out_target_path sysroot_path

4.build gcc

事先可以参照一下google的编译参数：

arm-eabi-gcc -v
Using built-in specs.
Target: arm-eabi
Configured with: /Volumes/project-jingyu/android_toolchain/build/../gcc/gcc-4.4.3/configure --prefix=/usr/local --target=arm-eabi --host=i686-apple-darwin --build=i686-apple-darwin --enable-languages=c,c++ --with-gmp=/Volumes/project-jingyu/toolchain-build/obj/temp-install --with-mpfr=/Volumes/project-jingyu/toolchain-build/obj/temp-install --disable-libssp --enable-threads --disable-nls --disable-libmudflap --disable-libgomp --disable-libstdc__-v3 --disable-sjlj-exceptions --disable-shared --disable-tls --with-float=soft --with-fpu=vfp --with-arch=armv5te --enable-target-optspace --with-abi=aapcs --with-gcc-version=4.4.3 --with-binutils-version=2.19 --with-gmp-version=4.2.4 --with-mpfr-version=2.4.1 --with-gdb-version=7.1.x --with-arch=armv5te --with-multilib-list=mandroid --with-sysroot=/Volumes/project-jingyu/cupcake_rel_root --enable-gold=both/gold --program-transform-name='s&^&arm-eabi-&'
Thread model: single
gcc version 4.4.3 (GCC)

接下来自己自己设定下自己的编译参数

../build/configure --with-gcc-version=4.4.3 --with-gmp-version=4.2.4 --with-binutils-version=2.19 --with-mpfr-version=2.4.1 --with-sysroot=sysroot_path --prefix=${PWD}/gccinstall --target=arm-eabi --build=x86_64-apple-darwin --with-multi-list=mandroid --enable-gold=both/gold --host=x86_64-apple-darwin --with-gdb-version=7.1.x

本人测试过，binutils的版本不对的话，编译OS的时候会出错，是ld的问题

由于mac的gcc 4.2目前默认带了-Wformat-security参数，编译binutils会有error，需要改下binutils-2.19的configure文件

在-Wall 后面添加 -Wno-format

make build

5.install

make install

至此android 使用的 arm-eabi-gcc 4.4.3 就编译完成了
