When compiling GCC,

Main references from http://blog.csdn.net/mcy_cool/article/details/17047027

Modified for some reason, marked red place for the modified place

Compilation Environment:
Kernel Name: Linux
Hardware schema name: i686
Hardware platform: I386
Operating system: Ubuntu 13.10
Current system GCC version number: 4.8.1

Target Platform OK6410:ARM11

First, the preparatory work

1. Download the source package

binutils-2.23.1.tar.bz2

gcc-4.8.2.tar.bz2
glibc-2.18.tar.bz2
glibc-linuxthreads-2.5.tar.bz2
gdb-7.6.1.tar.bz2
Linux-2.6.34.14.tar.xz
mpfr-3.1.2.tar.bz2
Mpc-1.0.1.tar.gz
gmp-5.1.3.tar.bz2

2. Prepare the SOFTWARE Environment
#apt-get Install Xz-utils
#apt-get Install M4
#apt-get Install Libncurses-dev
#apt-get Install g++
#apt-get Install Gawk

3, set the environment variables (recommended to be modified directly in the ~/.BASHRC, note that after the change to make the variable effective)
#vim ~/.BASHRC
Export Target=arm-linux-gnueabi
Export prefix=/usr/local/arm/4.8.2
Export target_prefix= $PREFIX/$TARGET
Export path= $PATH: $PREFIX/bin
#source ~/.BASHRC
4, for host installation MPFR, MPC, GMP
#tar-XJVF gmp-5.1.3.tar.bz2
#cd gmp-5.1.3
#mkdir Build && CD Build
#.. /configure--prefix=/usr/local/gmp--build=x86_64-linux-gnu
#make
#make Install

#tar-XJVF mpfr-3.1.2.tar.bz2
# CD mpfr-3.1.2
#.. /configure--build=x86_64-linux-gnu--PREFIX=/USR/LOCAL/MPFR--with-gmp=/usr/local/gmp
#make
#make Install

#tar-XZVF mpc-1.0.1.tar.gz
#cd mpc-1.0.1
#mkdir Build && CD Build
#.. /configure--build=x86_64-linux-gnu--PREFIX=/USR/LOCAL/MPC--with-gmp=/usr/local/gmp--WITH-MPFR=/USR/LOCAL/MPFR
#make
#make Install
5. Copy Linux-kernel-headers
#xz-D Linux-2.6.34.14.tar.xz
#tar-XVF Linux-2.6.34.14.tar
#cd linux-2.6.34.14
#make Menuconfig
Do not make changes and exit directly.
#make Include/linux/version.h
#mkdir-P $TARGET _prefix/include
#cp-R./include/linux/$TARGET _prefix/include
#cp-R./include/asm-generic/$TARGET _prefix/include
#cp-R./arch/arm/include/asm/$TARGET _prefix/include
Then go to the appropriate directory to see if the Version.h file was established successfully.

Second, compiling binutils
#tar-XJVF binutils-2.23.1.tar.bz2
#cd binutils-2.23.1
#mkdir Build && CD Build
#.. /configure--prefix= $PREFIX--target= $TARGET
#make
#make Install
When you are done, go to $prefix to check the generated tools.
# CD $PREFIX/bin
# LL
The following files are available:
arm-linux-addr2line*
arm-linux-ar*
arm-linux-as*
arm-linux-c++filt*
arm-linux-elfedit*
arm-linux-gprof*
arm-linux-ld*
arm-linux-ld.bfd*
arm-linux-nm*
arm-linux-objcopy*
arm-linux-objdump*
arm-linux-ranlib*
arm-linux-readelf*
arm-linux-size*
arm-linux-strings*
arm-linux-strip*
The resulting files have the following effects:
Arm-linux-addr2line: Turn the address you're looking for into a file and line number, and it's going to use the debug information
Arm-linux-ar: Generating, modifying, and unlocking an archive file
Arm-linux-as:gnu's Assembler
Arm-linux-c++filt:c++ and Java have an overloaded function, the overloaded function used by the end will be compiled into the assembly of the standard, c++filt is to achieve this reverse conversion, according to the label to get the function name
Arm-linux-elfedit: Use temporarily unknown
ARM-LINUX-GPROF:GNU Assembler Pre-compiler
The ARM-LINUX-LD:GNU connector
ARM-LINUX-LD.BFD: Use temporarily unknown
ARM-LINUX-NM: Lists the symbol and corresponding address of the target file
Arm-linux-objcopy: Convert a target file in one format to a different format target file
Arm-linux-objdump: Displays information about the destination file
Arm-linux-ranlib: An index is generated for an archive file, and the index is stored in an archive file
Arm-linux-readelf: Displays information about the target file in elf format
Arm-linux-size: Displays the size of each section of the target file and the size of the target file
Arm-linux-strings: Prints a string that can be printed in the destination file, with a default length of 4
Arm-linux-strip: Stripping all symbolic information from the target file

Third, establish the initial compiler (without GLIBC support)
#tar-XJVF gcc-4.8.2.tar.bz2
Re-unzip mpfr-3.1.2.tar.bz2, mpc-1.0.1.tar.gz, gmp-5.1.3.tar.bz2, and rename to gcc-4.8.2
#rm-rf mpfr-3.1.2 mpc-1.0.1 gmp-5.1.3
#tar-XJVF gmp-5.1.3.tar.bz2
#mv gmp-5.1.3 GMP
#mv./gmp./gcc-4.8.2
#tar-XJVF mpfr-3.1.2.tar.bz2
#mv mpfr-3.1.2 MPFR
#mv./mpfr./gcc-4.8.2
#tar-XZVF mpc-1.0.1.tar.gz
#mv mpc-1.0.1 MPC
#mv./mpc./gcc-4.8.2

#cd gcc-4.8.2
#mkdir Build
#cd Build
#.. /configure--prefix= $PREFIX--target= $TARGET--without-headers--enable-languages=c--disable-threads--with-newlib- -disable-shared--disable-libmudflap--DISABLE-LIBSSP--disable-decimal-float
#make ALL-GCC

#make INSTALL-GCC
#make ALL-TARGET-LIBGCC
#make INSTALL-TARGET-LIBGCC

After completion, $PREFIX/bin a few more files:
arm-linux-cpp*
arm-linux-gcc*
arm-linux-gcc-4.8.2*
arm-linux-gcov*
The resulting files have the following effects:
Arm-linux-cpp:gnu C's pre-compiler
C language Compiler for ARM-LINUX-GCC:GNU
Arm-linux-gcc-4.8.2:gnu C language compiler, in fact, and ARM-LINUX-GCC is the same
ARM-LINUX-GCOV:GCC Auxiliary testing tools for analyzing and optimizing programs

Iv. compiling glibc
GLIBC is the runtime of the cross-compilation environment.

#tar-xvf glibc-2.18.tar.xz
#tar-xvf glibc-linuxthreads-2.5.tar.bz2--directory=./glibc-2.18
# CD glibc-2.18
# mkdir Build
# cd Build
# cc= $TARGET-gcc
#export cflags= " -g-o2-march=arm "
# ln-s/usr/local/arm/4.8.2/lib/gcc/arm-linux-gnueabi/4.8.2/libgcc.a/usr/local/arm/ 4.8.2/LIB/GCC/ARM-LINUX-GNUEABI/4.8.2/LIBGCC_EH.A
Create Config.cache configuration file
# vim Config.cache
Libc_cv_forced_ Unwind=yes
Libc_cv_c_cleanup=yes
Libc_cv_arm_tls=yes
#.. /configure--host= $TARGET--target= $TARGET--prefix= $TARGET _prefix--enable-add-ons--disable-profile--cache-file= Config.cache--with-binutils= $PREFIX/bin--with-headers= $TARGET _prefix/include cc= $TARGET-gcc cflags= "-G o2– March-armv6 "

Note: The CC and cflags to modify will affect the subsequent compilation of GCC, resulting in CC using ARM-LINUX-GCC and cxx using g++ platform different error, where-MARCH-ARMV6 is 6410 ARM11 instruction set used
#make All
#make Install
V. Build a full set of compilers (fully GCC)
# CD gcc-4.8.2/build/
# RM-RF *
# .. /configure--prefix= $PREFIX--target= $TARGET--enable-shared--enable-languages=c,c++--with-arch=armv6–with-cpu= Arm1176jzf-s–with-tune=arm1176jzf-s–with-fpu=vfp

Description: 6410 contains the floating-point processor, adds it when compiling gcc, and the ARM11 architecture is the ARMV6 instruction set.
# make
# make Install

After completion, $PREFIX/bin a few more files:
arm-linux-c++*
arm-linux-g++*
The resulting files have the following effects:
C + + compiler for ARM-LINUX-G++:GNU
Arm-linux-c++: Equivalent to arm-linux-g++

Vi. compiling GDB
# TAR-XVF GDB-7.6.1.TAR.BZ2

#./configure--prefix= $PREFIX--target= $TARGET

Description: Red should be added, original error
# make
# make Install
Vii. Creating Links

# ln-s Arm-linux-gnueabi-strings arm-linux-strings
# ln-s Arm-linux-gnueabi-strip Arm-linux-strip
Viii. Verification
Use Vim to write a simple file, here hello.c for example (Cheng):

Then execute the compile command:
# arm-linux-gcc-static Hello.c–o Hello
Validates the final compiled file after compilation is complete. Instance:
# file Hello
Hello:elf 32-bit LSB executable, ARM, version 1, statically linked, for Gnu/linux 2.0.0, not stripped
As above output indicates the success of compiling the arm version of the program.

This completes.
