LINUX,GCC installation (decompression version) __linux

First , before installing GCC, you need to install dependencies:

1, GMP installation:

Download: gmp-6.0.0a.tar.bz2
decompression: Tar jxf gmp-6.0.0a.tar.bz2
cd gmp-6.0.0
./configure--prefix=/usr/local/ gmp-6.0.0 && make make
install

2, MPFR installation:

Download: mpfr-3.1.5.tar.gz
decompression: Tar zxvfv mpfr-3.1.5.tar.gz
cd mpfr-3.1.5
./configure--prefix=/usr/local/ mpfr-3.1.5--with-gmp=/usr/local/gmp-6.0.0 && make make
install

3. MPC Installation:

Download: mpc-1.0.2.tar.gz
decompression: Tar zxvfv mpc-1.0.2.tar.gz
cd mpc-1.0.2
./configure--prefix=/usr/local/ mpc-1.0.2--with-gmp=/usr/local/gmp-6.0.0--with-mpfr=/usr/local/mpfr-3.1.5 && make make
install

second, add to environment variables:

Note the path installed above
export ld_library_path= $LD _library_path:/usr/local/mpc-1.0.2/lib:/usr/local/gmp-5.0.1/lib:/usr/ Local/mpfr-3.1.5/lib
Add configuration:
vi/etc/ld.so.conf
/usr/local/gmp-5.0.1/lib
/usr/local/mpfr-3.1.5/ Lib
/usr/local/mpc-1.0.2/lib
execution:
ldconfig

4, gcc installation:

Download: gcc-4.5.1.tar.gz
decompression: Tar zxvfv gcc-4.5.1.tar.gz
cd gcc-4.5.1
./configure--prefix=/usr/local/ gcc-4.5.1
--enable-threads=posix--disable-checking--disable-multilib
--enable-languages=c,c++,java-- with-gmp=/usr/local/gmp-6.0.0
--with-mpfr=/usr/local/mpfr-3.1.5--with-mpc=/usr/local/mpc-1.0.2 make
# After a long wait ...
Make install

To View the installation path:

Whereis GCC

If there is an old GCC, replace the version:

Ln-s/usr/local/gcc-4.5.1/bin/gcc/usr/bin/gcc
