can not install squid

["Jephe Wu" <jephe usa net>]

After downloading squid-1.1.22.src.tar.gz , I tried to install it.but
--------------
[root sh-proxy squid-1.1.22]# ./configure --prefix=/usr/local/squid
loading cache ./config.cache
checking host system type... i486-pc-linux-gnu
checking for gcc... gcc
checking whether the C compiler (gcc  -g) works... no
configure: error: installation or configuration problem: C compiler cannot
creat
e executables.
----------------
what 'C compiler cannot create executables' means? how to fix it ?

Thank you !
