RedFlag Linux SP3 升级最新版gcc4.8.1

首先需要准备需要材料:

mpc-1.0.1.tar.gz
mpfr-3.1.2.tar.gz
gmp-5.1.3.tar.gz

分别解压缩
tar zxvf gmp-5.1.3.tar.gz
tar zxvf mpfr-3.1.2.tar.gz
tar zxvf mpc-1.0.1.tar.gz
解压之后, 按照下面步骤安装。

1. 安装gmp:
# ./configure
# make
# make check
这一步用来查看有没有文件不匹配或缺失,然后安装:
# make install

2. 安装mpfr

配置:
# ./configure --with-gmp-include=/usr/local/include --with-gmp-lib=/usr/local/lib
# make
# make check
接下来安装:
# make install

3. 安装mpc

配置:
# ./configure --with-gmp-include=/usr/local/include --with-gmp-lib=/usr/local/lib --with-mpfr-include=/usr/local/include --with-mpfr-lib=/usr/local/lib
# make
# make check
接下来安装:
# make install

准备工作完成,以下是gcc的安装与更新。



4. 配置

  在我的机器上,我是这样配置的:

  $ ./configure --prefix=/usr/local/gcc4.8 --with-gmp-include=/usr/local/include --with-gmp-lib=/usr/local/lib --with-mpfr-include=/usr/local/include --with-mpfr-lib=/usr/local/lib --with-mpc-include=/usr/local/include --with-mpc-lib=/usr/local/lib

(注:/usr/local/gcc4.8是自定的安装目录)

  将GCC安装在/usr/local/gcc4.8目录下。

5. 编译

  $ make

  
6. 安装

# make install

  至此,GCC 安装过程就完成了。
