我用的是RED HAT LINUX8.0，安装GCC时出现下面的对话，请高人指点一下。
[root@kispblcs gcc-3.2.2]# ./configure
Configuring for a i686-pc-linux-gnuoldld host.
Created "Makefile" in /root/gcc-3.2.2 using "mt-frag"
./configure: line 7: cc: command not found
*** The command 'cc -o conftest -g   conftest.c' failed.
*** You must set the environment variable CC to a working compiler.
