现在介绍一下在安装gcc时可能遇到的问题。
在安装gcc时，可能会提示要求安装下面几个软件包：
binutils-2.13.90.0.18-9.i386.rpm
cpp-3.2.2-5.i386.rpm
glibc-devel-2.3.2-11.9.i386.rpm
别担心，一步一步来。首先在red hat 第一张光盘中查找以上三个软件包，并安装它们。
[root@RedHat9 mnt]# mount /dev/cdrom /mnt/cdrom/
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@RedHat9 mnt]# find -iname binutils*
./cdrom/RedHat/RPMS/binutils-2.13.90.0.18-9.i386.rpm
[root@RedHat9 mnt]# rpm -ivh cdrom/RedHat/RPMS/binutils-2.13.90.0.18-9.i386.rpm

[root@RedHat9 mnt]# rpm -ivh cdrom/RedHat/RPMS/glibc-devel-2.3.2-11.9.i386.rpm
warning: cdrom/RedHat/RPMS/glibc-devel-2.3.2-11.9.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e
error: Failed dependencies:
kernel-headers is needed by glibc-devel-2.3.2-11.9
kernel-headers >;= 2.2.1 is needed by glibc-devel-2.3.2-11.9
这时不要查找kernel-headers，放心，你在三张光盘中都找不到kernel-headers的。你要查找glibc-kernheaders，看下面：
[root@RedHat9 mnt]# find -iname glibc-k*
./cdrom/RedHat/RPMS/glibc-kernheaders-2.4-8.10.i386.rpm
[root@RedHat9 mnt]# rpm -ivh cdrom/RedHat/RPMS/glibc-kernheaders-2.4-8.10.i386.rpm

到此为止，gcc所依赖的软件包都安装了，现在插入第二张光盘，安装gcc：
[root@RedHat9 mnt]# umount /mnt/cdrom
[root@RedHat9 mnt]# mount /dev/cdrom /mnt/cdrom/
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@RedHat9 mnt]# find -iname gcc*

./cdrom/RedHat/RPMS/gcc-objc-3.2.2-5.i386.rpm
[root@RedHat9 mnt]# rpm -ivh cdrom/RedHat/RPMS/gcc-3.2.2-5.i386.rpm

现在查看一下gcc有没有装好：
[root@RedHat9 mnt]# rpm -qa gcc*
gcc-3.2.2-5
[root@RedHat9 mnt]#
gcc安装成功
