1、编译binutils

/path/to/binutils/source/configure --build=x86_64-centos-linux-gnu \
--host=x86_64-centos-linux-gnu --target=arm-cortex_a8-linux-gnueabi \
--prefix=/path/to/install
make -j4
make install

2、编译安装gcc-core

make all-gcc
make install-gcc

3、编译目标libc（glibc或eglibc）

/path/to/libc/source/configure --build=x86_64-centos-linux-gnu \
--host=arm-cortex_a8-linux-gnueabi --target=arm-cortex_a8-gnueabi \
--prefix=/usr
make -j4 
make -j4 install_root=${SYSROOT} install

4、编译完整gcc

make -j4 
make install

Just For Me

1.

--host=x86_64-centos-linux-gnu --target arm-cortex_a8-linux-gnueabi \
--prefix=/opt/arm-cortex_a8-linux-gnueabi --with-float=softfp \
--with-sysroot=/opt/arm-cortex_a8-linux-gnueabi/sysroot --enable-lto \
--disable-nls
make -j6
make install
