      1. TARGET=arm-linux-gnueabi
      2. PREFIX=/opt/cross/gcc-4.7.2/$TARGET
      3. PATH=$PREFIX/bin:$PATH
      4. LD_LIBRARY_PATH=/opt/gmp-5.0.5/lib:/opt/mpfr-3.1.1/lib:/opt/mpc-1.0.1/lib
      5. export TARGET PREFIX PATH LD_LIBRARY_PATH

   3. cd mpc-1.0.1
   4. ./configure –prefix=/opt/ mpc-1.0.1 –with-gmp=/opt/gmp-5.0.5  –with-mpfr=/opt/mpfr-3.1.1
   5. make && make check && sudo make install
8. 第一次编译gcc
   1. mkdir gcc-bootstrap-build
   2. cd  gcc-bootstrap-build
   3. ../gcc-4.7.2/configure –target=$TARGET –host=x86-linux-gnu –build=x86-linux-gnu  –enable-targets=all –prefix=$PREFIX   –enable-languages=c –with-newlib –without-headers –disable-nls  –disable-threads –disable-shared –disable-libmudflap –disable-libssp  –disable-libgomp –disable-decimal-float –enable-checking=release  –disable-bootstrap –disable-libquadmath  –with-gmp=/opt/gmp-5.0.5 –with-mpfr=/opt/mpfr-3.1.1 –with-mpc=/opt/mpc-1.0.1
   4. make -j2 all-gcc
   5. make -j2 all-target-libgcc
   6. make install-gcc
   7. make install-target-gcc 
   8. cp -v libiberty/libiberty.a $PREFIX/lib 
   9. 以下两个添加 libgcc_eh.a，  ,libgcc_s.a到 libgcc.a的软链接
   10. ln -vs libgcc.a `arm-linux-gnueabi-gcc -print-libgcc-file-name | sed ‘s/libgcc/&_eh/’`
   11. ln -vs libgcc.a `arm-linux-gnueabi-gcc -print-libgcc-file-name | sed ‘s/libgcc/&_s/’` 
   12. cd ..
9. 安装内核头文件

Issue:

    configure: error: libmpfr not found or uses a different ABI (including static vs shared).

Solution:

    apt-get install libmpfr-dev

Issue:

    checking for suffix of object files… configure: error: in `/share/arm-tool/glibc-build’: 

    configure: error: cannot compute suffix of object files: cannot compile

Solution:

    export LD_LIBRARY_PATH=/opt/gmp-5.0.5/lib:/opt/mpfr-3.1.1/lib:/opt/mpc-1.0.1/lib

Issue:

    arm-linux-gnueabi/bin/ld: cannot find -lgcc

Solution:

    回到gcc编译目录执行以下命令

        make all-target-libgcc

        make install-target-libgcc

Issue:

    cannot find -lgcc_s

Solution:

    http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo/src/patchsets/glibc/2.16.0/

    下载0040_all_glibc-2.16-no-libgcc_s.patch文件打补丁

     patch -p1 -d glibc-2.16.0 < 0040_all_glibc-2.16-no-libgcc_s.patch

Issue:

    /opt/cross/gcc-4.7.2/arm-linux-gnueabi/lib/gcc/arm-linux-gnueabi/4.7.2/libgcc.a(libunwind.o): In function `_Unwind_Resume’:

    /share/arm-tool/gcc-bootstrap-build/arm-linux-gnueabi/libgcc/../../../gcc-4.7.2/libgcc/config/arm/libunwind.S:347: multiple definition of `_Unwind_Resume’

    /share/arm-tool/glibc-build/elf/static-stubs.o:/share/arm-tool/glibc-2.16.0/elf/static-stubs.c:32: first defined here

Solution:

    直接修改static-stubs.c,去除该函数定义
