更新LINUX编译系统求助

sofast

我想更新LINUX的编译系统,下载了gcc-3.4.1, 然后执行下面的操作:
1 在/usr 下解压
tar xvfz gcc-3.4.1.tar.gz
2 建立gcc-3.4.1_obj目录
mkdir gcc-3.4.1_obj
3 进行软件安装路径配置
cd gcc-3.4.1_obj
../gcc-3.4.1/configure --prefix /usr
4 编译gcc/g77
make bootstrap
出现错误

[root@localhost usr]# mkdir gcc-3.4.1_obj
[root@localhost usr]# pwd
/usr
[root@localhost usr]# cd gcc-3.4.1_obj
[root@localhost gcc-3.4.1_obj]# pwd
/usr/gcc-3.4.1_obj
[root@localhost gcc-3.4.1_obj]# ../gcc-3.4.1/configure --prefix /usr
