Compiling and installing GCC

1. Download the GCC source package: gcc-4.6.3.tar.bz2

2. Download gcc Dependency pack: gmp-5.0.4.tar.bz2, mpfr-3.1.0.tar.bz2, mpc-0.9.tar.gz

3. Decompression gcc-4.6.3.tar.bz2 instruction = "[Flydream@flydream opt]$ TAR-XVF gcc-4.6.3.tar.bz2

4. Enter [Flydream@flydream opt]$ CD gcc-4.6.3

5. Put the downloaded gmp-5.0.4.tar.bz2, mpfr-3.1.0.tar.bz2, mpc-0.9.tar.gz package into the gcc-4.6.3 directory

6. In the gcc-4.6.3 directory to extract the above three packets respectively

Install gmp-5.0.4.tar.bz2 First

Access to GMP directory: CD gmp-5.0.4

To establish the installation path: mkdir Gmp_install

CD Gmp_install

.. /configure--prefix=/opt/gcc-4.6.3/gmp-5.0.4/gmp_install

Make

Make install

Install mpfr-3.1.0.tar.bz2

Enter MPFR Directory

[Flydream@flydream gcc-4.6.3]$ CD mpfr-3.1.0

To establish the installation path: mkdir Mpfr_install

CD Mpfr_install

.. /configure--prefix=/opt/gcc-4.6.3/mpfr-3.1.0/mpfr_install--with-gmp=/opt/gcc-4.6.3/gmp-5.0.4/gmp_install

Make

Make install

Then install mpc-0.9.tar.gz

Into the MPC

To establish the installation path: mkdir Mpc_install

CD Mpc_install

.. /configure--prefix=/opt/gcc-4.6.3/mpc-0.9/mpc_install--with-gmp=/opt/gcc-4.6.3/gmp-5.0.4/gmp_install-- With-mpfr=/opt/gcc-4.6.3/mpfr-3.1.0/mpfr_install

Make

Make install

A "configure:error:cannot compute suffix of object Files:cannot compile" error may occur during the compilation of GCC, and the solution is:

Export Ld_library_path= $LD _library_path:/opt/gcc-4.6.3/mpc-0.9/mpc_install/lib:/opt/gcc-4.6.3/gmp-5.0.4/gmp_ Install/lib:/opt/gcc-4.6.3/mpfr-3.1.0/mpfr_install/lib

Last Install GCC

Set up the installation path outside of the GCC source directory

mkdir Gcc_install

.. /configure--prefix=/opt/gcc_install--with-gmp=/opt/gcc-4.6.3/gmp-5.0.4/gmp_install--with-mpfr=/opt/gcc-4.6.3/ Mpfr-3.1.0/mpfr_install----With-mpc=/opt/gcc-4.6.3/mpc-0.9/mpc_install--enable-checking=release-- program-suffix=4.6.3--enable-languages=c,c++

Make

Make install

Note the –program-suffix parameter, which represents the suffix of the generated executable file. The –enable-languages parameter represents the language to support. Final make; Make install. Make is also a small tip: because gcc files a lot, compile very slowly, you can use make-j n parameters, open multithreaded editing. Where the n value can be set to machine CPU kernel number x2.

Once compiled, you can use/opt/gcc-4.6.3/bin/gcc-4.6.3 to compile the C program. For ease of use,/opt/gcc-4.6.3/bin/gcc-4.6.3/bin can be placed in the system path:

Export path= $PATH:/opt/gcc-4.6.3/bin/gcc-4.6.3/bin

Building arm-linux-gnueabi-gcc-4.6.3 Cross-compilation chain

First, preparatory work

1. Prepare documents

binutils-2.22.tar.bz2

gcc-4.6.3.tar.bz2

Glibc-2.14.1.tar.xz

Glibc-ports-2.14.1.tar.gz

glibc-linuxthreads-2.5.tar.bz2

gdb-7.4.1.tar.bz2

linux-2.6.38.8.tar.bz2

mpfr-3.1.1.tar.bz2

Mpc-1.0.1.tar.gz

gmp-5.1.0.tar.bz2

2, set up the following variables, easy to wait for the input

#vim ~/.BASHRC

Export Target=arm-linux-gnueabi
Export prefix=/usr/local/arm-linux-gcc/4.6.3
Export target_prefix= $PREFIX/$TARGET
Export path= $PATH: $PREFIX/bin

3, for host installation MPFR, MPC, GMP

#tar-XVF gmp-5.1.0.tar.bz2

#cd gmp-5.1.0

#mkdir Build

#cd Build

#.. /configure

#make All-j4

#make Install

#tar-XVF mpfr-3.1.1.tar.bz2

# CD mpfr-3.1.1
#mkdir Build

#cd Build

#.. /configure

#make All-j4

#make Install

#tar-XVF mpc-1.0.1.tar.gz

#cd mpc-1.0.1

#mkdir Build

#cd Build

#.. /configure

#make All-j4

#make Install

4. Copy Linux-kernel-headers

#tar-XVF linux-2.6.38.8.tar.bz2

#cd linux-2.6.38.8

#make Include/linux/version.h
CHK Include/linux/version.h
UPD 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

Second, compile Binutils

#tar-XVF binutils-2.22.tar.bz2

#cd binutils-2.22

#mkdir Build

#cd Build

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

#make All-j4

#make Install

Iii. Preliminary compilation of GCC (without glibc support)

#tar-XVF gcc-4.6.3.tar.bz2

Re-extract mpfr-3.1.1.tar.bz2, mpc-1.0.1.tar.gz, gmp-5.1.0.tar.bz2, and change the name to gcc-4.6.3

#rm-rf mpfr-3.1.1 mpc-1.0.1 gmp-5.1.0

#tar-XVF gmp-5.1.0.tar.bz2

#mv gmp-5.1.0 GMP

#mv./gmp./gcc-4.6.3

#tar-XVF mpfr-3.1.1.tar.bz2

#mv mpfr-3.1.1 MPFR

#mv./mpfr./gcc-4.6.3

#tar-XVF mpc-1.0.1.tar.gz

#mv mpc-1.0.1 MPC

#mv./mpc./gcc-4.6.3

#cd gcc-4.6.3

#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-j4

#make INSTALL-GCC

#make All-target-libgcc-j4

#make INSTALL-TARGET-LIBGCC

Iv. compiling glibc

#tar-XVF glibc-ports-2.14.1.tar.gz

#mv glibc-ports-2.14.1 Ports
#mv./ports/./glibc-2.14.1

#tar-XVF glibc-linuxthreads-2.5.tar.bz2--directory=./glibc-2.14.1

# CD glibc-2.14.1

# mkdir Build

# CD Build

# cc= $TARGET-GCC

# ln-s/usr/local/arm-linux-gcc/4.6.3/lib/gcc/arm-linux-gnueabi/4.6.3/libgcc.a/usr/local/arm-linux-gcc/4.6.3/lib /gcc/arm-linux-gnueabi/4.6.3/libgcc_eh.a
