Gcc的一个问题

Gcc的一个问题

我用的是REDHAT LINUX7.3(网上当的)
下载了个GCC3.0安装提示:
CHECKING HOST SYSTEM TYPE --I686-PC-LINUX-GNUOLDLD
CHECKING FOR GCC NO
CHECKING FOR CC NO
还有我的机器是C433 64M 8.4G
是不是我的机器不支持?
./configure
提示:
CHECKING FOR A--I686-PC-LINUX-GNUOLDLD HOST

CREATED 'MAKEFILE" IN /ROOT/XIAZAI/GCC-3.0 USING 'MT-FRAG'

./CONFIGURE:CC:COMMAND NOT FOUND

*** THE COMMAND 'CC -O CONFTEST -G CONFTEST.C' FAILED

*** YOU MUST SET THE ENVIRONMENT VARIABLE CC TO WORKING COMPILER.

请问我是不是缺少CC这个文件.?
如果是的话,我应该怎么安装?
(没LINUX安装盘)      
root@localhost gcc-3.0]# alias cc=gcc
[root@localhost gcc-3.0]#./configure
configuring for ai686-pc-linux-gnuoldld host
created "makefile" in /root/xiazai/gcc-3.0 using "mt-frag"
./configure: cc: command not found
***the command 'cc -o conftest -g  conftest.c' failed.
***you must set the environment variable
CC to a working compiler.


我该怎么办?
      
which cc
有CC吗?      
/usr/bin/which: no cc in (/usr/local/sbin:/sbin:/usr/sbin:/bin:/usr/bin:/usr/bin/X11:/usr/local/bin:/usr/bin:/usr/X11R6/bin:/root/bin:/root/bin)      
我相信你连GCC可能都没有,
装一个吧
