编译C／C++源文件

为什么我装了红旗linux6以后，在控制台里输入gcc或g++无效，提示找不到此命令？只有gcc32 和g++32有效。但是用这两个命令边一个helloworld.c或helloworld.cpp编译不了。
用gcc32编译hellolworld.c结果如下：
#gcc32 helloworld.c
hello.c:1:18: stdio.h: 没有那个文件或目录

用g++32编译helloworld.cpp结果如下(一堆错误，救命呀）：
[root@liulinux ~]# g++32 hello.cpp

有人说看装了glibc没，我找了一下，确实装了呀。高手帮忙呀。
