linux编译安装gcc5.3.0-ag真人游戏

1、下载gcc5.3.0安装包

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

2、解压

#tar -zxf gcc-5.3.0.tar.gz

3、创建安装目录

#mkdir /usr/local/gcc-5.3.0/
#cd /usr/local/gcc-5.3.0/

4、配置安装

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

如果出现如下错误：

说明缺少依赖库gmp、mpfr、mpc，可以从ftp://gcc.gnu.org/pub/gcc/infrastructure/下载，按下面顺序安装。

⑴ 安装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
#make install

⑵ 安装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
#make install

⑶ 安装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
#make install

5、再次配置gcc安装配置选项

#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、编译

#make

大约半小时编译完成......

7、安装

#make install

8、软链接

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

9、添加环境变量

# vim /etc/bashrc

添加如下代码：

#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

安装完毕！
