1. 代码结构为:

setup ---> 源代码压缩包

:~/code/cross-compile$ ls setup/
binutils-2.24.tar.bz2  gcc-4.7.1.tar.bz2  gdb-7.6.2.tar.bz2   glibc-2.18.tar.bz2              linux-3.10.tar.bz2
gcc-4.6.4.tar.bz2      gcc-4.8.0.tar.bz2  glibc-2.17.tar.bz2  glibc-linuxthreads-2.5.tar.bz2  termcap-1.3.1.tar.gz
src --->源码

~/code/cross-compile$ ls src/
binutils-2.24  gcc-4.7.1  gdb-7.6.2  glibc-2.18

build --> 编译目录

:~/code/cross-compile$ ls build/
binutils  gcc  gdb  glibc

kernel ----> 内核代码:

~/code/cross-compile/kernel$ ls
linux-3.10

2.编译 binutils

在build/binutils 下,执行命令:

 ../../src/binutils-2.24/configure --target=mipsel-linux-gnueabi --prefix=/home/charles/code/cross-compile/embedded-toolchain/cross-tools --with-sysroot=/home/charles/code/cross-compile/embedded-toolchain
然后,执行 make, make install 安装

3. 编译  GCC stage 1

在 build/gcc目录下,执行

AR=ar LDFLAGS="-Wl,-rpath=/home/charles/code/cross-compile/embedded-toolchain/cross-tools/lib" ../../src/gcc-4.7.1/configure --prefix=/home/charles/code/cross-compile/embedded-toolchain/cross-tools --target=mipsel-linux-gnueabi  --with-sysroot=/home/charles/code/cross-compile/embedded-toolchain --with-gmp=/usr/local --with-mpfr=/usr/local --with-ppl=/usr/local --with-newlib --without-headers --disable-multilib --disable-nls --disable-decimal-float --disable-libgomp --disable-libmudflap --disable-libssp --disable-shared --disable-threads --enable-languages=c  --with-float=soft --with-arch=mips32r2 --with-tune=mips32r2
然后,

make all-gcc all-target-libgcc

make install-gcc install-target-libgcc

4. 安装内核头文件

进入到内核代码目录,

执行命令:

ARCH=mips make mrproper
ARCH=mips make headers_check
ARCH=mips CROSS_COMPILE=mipsel-gcc-linux-gnueabi make INSTALL_HDR_PATH=/home/charles/code/cross-compile/embedded-toolchain/usr headers_install
 find /home/charles/code/cross-compile/embedded-toolchain/usr/include/ -name ".install" -or -name "..install.cmd" | xargs rm -fv ;\

5. 编译 GLIBC

进入到 build/glibc,执行

BUILD_CC=gcc CC=mipsel-linux-gnueabi-gcc AR=mipsel-linux-gnueabi-ar RANLIB=mipsel-linux-gnueabi-ranlib ../../src/glibc-2.18/configure --prefix=/usr --host=mipsel-linux --enable-add-ons --with-fp=no libc_cv_forced_unwind=yes libc_cv_c_cleanup=yes libc_cv_ctors_header=yes --with-tune=mips32r2 --with-arch=mips32r2 --with-headers=/home/charles/code/cross-compile/embedded-toolchain/usr/include
把步骤3生成的mipsel gcc 加入到  path:

export PATH=$PATH:/home/charles/code/cross-compile/embedded-toolchain/cross-tools/bin
执行

make
make install install_root=/home/charles/code/cross-compile/embedded-toolchain
6.编译最后的GCC

 AR=ar LDFLAGS="-Wl,-rpath=/home/charles/code/cross-compile/embedded-toolchain/cross-tools/lib" ../../src/gcc-4.7.1/configure --prefix=/home/charles/code/cross-compile/embedded-toolchain/cross-tools --target=mipsel-linux-gnueabi --with-sysroot=/home/charles/code/cross-compile/embedded-toolchain --with-gmp=/usr/local --with-mpfr=/usr/local --with-ppl=/usr/local --disable-multilib --disable-libssp  --disable-nls --disable-libstdcxx-pch --with-arch=mips32r2 --with-tune=mips32r2 --enable-languages=c,c++  --with-float=soft  --with-mips-plt --disable-libgomp --disable-libmudflap --enable-poison-system-directories --enable-symvers=gnu --enable-long-long --enable-threads --enable-shared --enable-lto --enable-__cxa_atexit --with-gnu-as --with-gnu-ld

再执行

make all-gcc -j10 -i -k
make all-target-libgcc
make install-gcc
make  install-target-libgcc
make
make install


最后,看一下生成的gcc的信息:

./mipsel-linux-gnueabi-gcc -v 
Using built-in specs.
COLLECT_GCC=./mipsel-linux-gnueabi-gcc
COLLECT_LTO_WRAPPER=/home/charles/toolchain/embedded-toolchain/cross-tools/bin/../libexec/gcc/mipsel-linux-gnueabi/4.7.1/lto-wrapper
Target: mipsel-linux-gnueabi
Configured with: ../../src/gcc-4.7.1/configure --prefix=/home/charles/code/cross-compile/embedded-toolchain/cross-tools --target=mipsel-linux-gnueabi --with-sysroot=/home/charles/code/cross-compile/embedded-toolchain --with-gmp=/usr/local --with-mpfr=/usr/local --with-ppl=/usr/local --disable-multilib --disable-libssp --disable-nls --disable-libstdcxx-pch --with-float=soft --with-arch=mips32r2 --with-tune=mips32r2 --enable-languages=c,c++ --with-float=soft --with-mips-plt --disable-libgomp --disable-libmudflap --enable-poison-system-directories --enable-symvers=gnu --enable-long-long --enable-threads --enable-shared --enable-lto --enable-__cxa_atexit --with-gnu-as --with-gnu-ld
Thread model: posix
gcc version 4.7.1 (GCC)
