linux編譯安裝gcc5.3.0

1、下載GCC5.3.0安裝包

#su

#cd /opt

#wget http://ftp.gnu.org/gnu/gcc/gcc-5.3.0/gcc-5.3.0.tar.gz

2、解壓

#tar -zxf gcc-5.3.0.tar.gz

3、創建安裝目錄

#mkdir /usr/local/gcc-5.3.0/

#cd /usr/local/gcc-5.3.0/

4、配置安裝

#/opt/gcc-5.3.0/configure -prefix=/usr/local/gcc-5.3.0

如果出現如下錯誤：

說明缺少依賴庫GMP、MPFR、MPC，可以從ftp://gcc.gnu.org/pub/gcc/infrastructure/下載，按下面順序安裝。

⑴ 安裝GMP4.3.2

#cd /opt

#wget ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-4.3.2.tar.bz2

#tar jxvf gmp-4.3.2.tar.bz2

#mkdir /usr/local/gmp-4.3.2

#cd /usr/local/gmp-4.3.2

#/opt/gmp-4.3.2/configure -prefix=/usr/local/gmp-4.3.2

#make -j 4

#make install

⑵ 安裝MPFR2.4.2

#cd /opt

#wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpfr-2.4.2.tar.bz2

#tar jxvf mpfr-2.4.2.tar.bz2

#mkdir /usr/local/mpfr-2.4.2

#cd /usr/local/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

#make -j 4

#make install

⑶ 安裝MPC0.8.1

#cd /opt

#wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpc-0.8.1.tar.gz

#tar -zxf mpc-0.8.1.tar.gz

#mkdir /usr/local/mpc-0.8.1

#cd /usr/local/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

#make -j 4

#make install

5、再次配置GCC安裝配置選項

#cd /usr/local/gcc-5.3.0

#/opt/gcc-5.3.0/configure --prefix=/usr/local/gcc-5.3.0 -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

#make -j 4

大約半小時編譯完成......

7、安裝

#make install

8、軟鏈接

#ln -s /usr/local/gcc-5.3.0/bin/gcc gcc 
#ln -s /usr/local/gcc-5.3.0/bin/g++ g++

9、添加環境變量

# vim /etc/bashrc

添加如下代碼：

#gcc

LD_LIBRARY_PATH=:/usr/local/mpc-0.8.1/lib:/usr/local/gmp-4.3.2/lib:/usr/local/mpfr-2.4.2/lib:/usr/local/gcc-5.3.0/lib:/usr/local/gcc-5.3.0/lib64

#export LD_LIBRARY_PATH

安裝完畢！
