RedHat5.4更新安裝GCC-4.8.3

安裝的redhat版本

[[email protected] ~]$ lsb_release -a

LSB Version:    :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch

Distributor ID: RedHatEnterpriseServer

Description:    Red Hat Enterprise Linux Server release 5.4 (Tikanga)

Release:        5.4

Codename:       Tikanga

1.下載下傳gcc-4.6.1安裝包

gcc各版本浏覽位址:http://ftp.gnu.org/gnu/gcc/

2.将gcc-4.6.1.tar.bz2放到/opt檔案夾下解壓

[[email protected] ~]# cd /opt

[[email protected] opt]# tar -xjvf gcc-4.8.3.tar.bz2

3.建立安裝目錄

[[email protected] opt]# mkdir /usr/local/gcc-4.8.3/

4.進入安裝目錄

[[email protected] opt]# cd /usr/local/gcc-4.8.3/

5.配置安裝檔案

[[email protected] gcc-4.8.3]# /opt/gcc-4.8.3/configure --prefix=/usr/local/gcc-4.8.3

(執行源目錄 /opt/gcc-4.8.3/中的configure指令,配置将gcc安裝到目标目錄/usr/local/gcc-4.8.3/下,這裡–prefix選項代表要将該庫安裝在哪裡,我是裝在/usr/local/gcc-4.8.3目錄下,後面的安裝都會用到這個選項)

如果執行這步的時候出現了如下錯誤:

----------------------------------------------------------------------------------

configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+.

Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify

their locations.

----------------------------------------------------------------------------------

錯誤說明要安裝gcc需要GMP、MPFR、MPC這三個庫,可從ftp://gcc.gnu.org/pub/gcc/infrastructure/下載下傳相應的壓縮包。由于MPFR依賴GMP,而MPC依賴GMP和MPFR,是以要先安裝GMP,其次MPFR,最後才是MPC。這裡三個庫我用的版本分别是gmp4.3.2,mpfr2.4.2和mpc0.8.1,都放在 /opt檔案夾下。

①.安裝gmp4.3.2

[ [email protected] opt]# tar jxvf gmp-4.3.2.tar.bz2

[ [email protected] opt]# mkdir /usr/local/gmp-4.3.2

[ [email protected] opt]# cd /usr/local/gmp-4.3.2

[ [email protected] gmp-4.3.2]# /opt/gmp-4.3.2/configure --prefix=/usr/local/gmp-4.3.2

[ [email protected] gmp-4.3.2]# make (編譯)

[ [email protected] gmp-4.3.2]# make install (執行安裝)

②安裝mpfr2.4.2

[ [email protected] opt]# tar jxvf mpfr2.4.2.tar.bz2

[ [email protected] opt]# mkdir /usr/local/mpfr-2.4.2

[ [email protected] opt]# cd /usr/local/mpfr-2.4.2

[ [email protected] mpfr-2.4.2]# /opt/mpfr-2.4.2/configure --prefix=/usr/local/mpfr-2.4.2 --with-gmp=/usr/local/gmp-4.3.2

(注意配置的時候要把依賴關系選項加進去)

[ [email protected] mpfr-2.4.2]# make

[ [email protected] mpfr-2.4.2]# make install

③安裝mpc0.8.1

[ [email protected] opt]# tar jxvf gmpc0.8.1.tar.bz2

[ [email protected] opt]# mkdir /usr/local/mpc-0.8.1

[ [email protected] opt]# cd /usr/local/mpc-0.8.1

[ [email protected] mpc-0.8.1]# /opt/mpc-0.8.1/configure --prefix=/usr/local/mpc-0.8.1 --with-gmp=/usr/local/gmp-4.3.2 --with-mpfr=/usr/local/mpfr-2.4.2

[ [email protected] mpc-0.8.1]# make

[ [email protected] mpc-0.8.1]# make install

④再次安裝GCC 配置安裝選項

[ [email protected] mpc-0.8.1]# cd /usr/local/gcc- 4.8.3

[ [email protected] gcc- 4.8.3]# /opt/gcc- 4.8.3/configure --prefix=/usr/local/gcc- 4.8.3 -enable-threads=posix -disable-checking -disable-multilib -enable-languages=c,c++ --with-gmp=/usr/local/gmp-4.3.2 --with-mpfr=/usr/local/mpfr-2.4.2 --with-mpc=/usr/local/mpc-0.8.1

6.編譯安裝檔案

[ [email protected] gcc-4.8.3]# make

大概需要1個小時左右

第二個錯誤出現了:

打開/usr/local/gcc-4.8.3/i686-pc-linux-gnu/libgcc/config.log

ctrl+f查找error 發現如下錯誤

/----------------------------------------------------------------------------------

/usr/local/gcc-4.8.3/./gcc/cc1: error while loading shared libraries: libmpc.so.2: cannot open shared object file: No such file or directory

configure:3058: $? = 1

----------------------------------------------------------------------------------/

在網上找到了解決方法,需要添加環境變量LD_LIBRARY_PATH以指出前面三個庫的位置,鍵入以下指令:

[[email protected] gcc-4.8.3]# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/mpc-0.8.1/lib:/usr/local/gmp-4.3.2/lib:/usr/local/mpfr-2.4.2/lib

再次執行步驟6→

大概三小時後···

終于編譯成功了,效果圖入下:

RedHat5.4更新安裝GCC-4.8.3

7.執行安裝gcc

[[email protected] gcc-4.8.3]# make install

[[email protected] gcc-4.8.3]# 

如果不出意外,那麼到現在應該安裝成功了,不過還是不能使用新版本的gcc,因為新版本的gcc還沒有加入指令搜尋路徑中!

8.建立軟連結

[[email protected] /]# sudo ln -s /usr/local/gcc-4.8.3/bin/gcc gcc48

[[email protected] /]# sudo ln -s /usr/local/gcc-4.8.3/bin/g++ g++48

9.添加環境變量 

[root@localhost linfeng]# export PATH=$PATH:/usr/local/gcc-4.8.3/bin/
