   1. You might check to output message like next.

   2. Move to directory of binutils zip (For example, My version of binutils is 2.24.51.)

       Anonymous@Anonymous-PC ~
       $ cd /usr/src/binutils-**[tap]**
   
       Anonymous@Anonymous-PC /usr/src/binutils-2.25-1.src

   3. unzip to binutils-gdb-*.tar.bz2

   4. move to unzip directory

       Anonymous@Anonymous-PC /usr/src/binutils-2.25-1.src/binutils-gdb-2.25/binutils-gdb
       $ 
   

   5. export environment variables to TARGET and PREFIX

       Anonymous@Anonymous-PC /usr/src/binutils-2.25-1.src/binutils-gdb-2.25/binutils-gdb
       $ export TARGET=x86_64-pc-linux
   
       Anonymous@Anonymous-PC /usr/src/binutils-2.25-1.src/binutils-gdb-2.25/binutils-gdb
       $ export PREFIX=/usr/cross
   

   6. binutils source - configure

       Anonymous@Anonymous-PC /usr/src/binutils-2.25-1.src/binutils-gdb-2.25/binutils-gdb
       $ ./configure --target=$TARGET --prefix=$PREFIX --enable-64bit-bfd --disable-shared --disable-nls
   

   7. modify to environment information of build

       Anonymous@Anonymous-PC /usr/src/binutils-2.25-1.src/binutils-gdb-2.25/binutils-gdb
       $ make configure-host
   

   8. Build to binutils

       Anonymous@Anonymous-PC /usr/src/binutils-2.25-1.src/binutils-gdb-2.25/binutils-gdb
       $ make all
   

   9. Install to binutils

       Anonymous@Anonymous-PC /usr/src/binutils-2.25-1.src/binutils-gdb-2.25/binutils-gdb
       $ make install
   

   10. Supported to 64bit mode check

       Anonymous@Anonymous-PC /usr/src/binutils-2.25-1.src/binutils-gdb-2.25/binutils-gdb
       $ /usr/cross/bin/x86_64-pc-linux-ld --help | grep "supported"
       x86_64-pc-linux-ld: supported targets: elf64-x86-64 elf32-i386 elf32-x86-64 a.out-i386-linux pei-i386 pei-x86-64 elf64-l1om elf64-k1om elf64-little elf64-big elf32-little elf32-big srec symbolsrec verilog tekhex binary ihex

3. Build and Install to Cross-GCC compiler

   1. You might check to output message like next.

       Anonymous@Anonymous-PC ~
       $
   

   2. If you want to install cross compiler about gcc, it should checked about install of library like next.

      • libgmp-devel
      • libmpfr-devel
      • libmpc-devel

   3. Move to directory of gcc zip (For example, My version of gcc is 4.8.3.)

       Anonymous@Anonymous-PC ~
       $ cd /usr/src/gcc-**[tap]**
   
       Anonymous@Anonymous-PC /usr/src/gcc-4.8.3-3.src
       $ 
   

   4. unzip to gcc-*.tar.bz2

      • If you want to install cross compiler safe, it should not use tar. instead you can use bandizip or other unzip programs.

   5. move to unzip directory

       Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2
       $ 
   

   6. export environment variables to TARGET and PREFIX, PATH

       Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2
       $ export TARGET=x86_64-pc-linux
   
       Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2
       $ export PREFIX=/usr/cross
   
       Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2
       $ export PATH=$PREFIX/bin:$PATH
   

   7. gcc source - configure

   Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2 $ ./configure --target=$TARGET --prefix=$PREFIX --disable-nls --enable-languages=c,c++ --without-headers --disable-shared --enable-multilib

   
       - If you want to build about gcc only, `--enable-languages` option value is `c`.
   
   
   8. modify to environment information of build
       ```
   Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2
       $ make configure-host
   

   9. Copy to library about build of gcc and g++

       Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2
       $ cp /lib/gcc/i686-pc-cygwin/4.9.2/libgcc_s.dll.a /lib/gcc/i686-pc-cygwin/4.9.2/libgcc_s.a
   
       Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2
       $ cp /lib/libmpfr.dll.a /lib/libmpfr.a
   
       Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2
       $ cp /lib/libgmp.dll.a /lib/libgmp.a
   
       Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2
       $ cp /lib/libmpc.dll.a /lib/libmpc.a
   

   10. Build to gcc & g++

   Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2 $ make all-gcc

   
   11. Install to `gcc` & `g++`
       ```
   Anonymous@Anonymous-PC /usr/src/gcc-4.9.2-1.src/gcc-4.9.2
       $ make install-gcc
