現在介紹一下在安裝gcc時可能遇到的問題。
在安裝gcc時，可能會提示要求安裝下面幾個軟件包：
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

別擔心，一步一步來。首先在red hat 第一張光盤中查找以上三個軟件包，并安裝它們。

[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]# find -iname glibc-devel*
./cdrom/RedHat/RPMS/glibc-devel-2.3.2-11.9.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

這時不要查找kernel-headers，放心，你在三張光盤中都找不到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

1:glibc-devel          ########################################### [100%]

到此為止，gcc所依賴的軟件包都安裝了，現在插入第二張光盤，安裝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-3.2.2-5.i386.rpm
./cdrom/RedHat/RPMS/gcc-c++-3.2.2-5.i386.rpm
./cdrom/RedHat/RPMS/gcc-g77-3.2.2-5.i386.rpm
./cdrom/RedHat/RPMS/gcc-gnat-3.2.2-5.i386.rpm
./cdrom/RedHat/RPMS/gcc-java-3.2.2-5.i386.rpm
./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
warning: cdrom/RedHat/RPMS/gcc-3.2.2-5.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e

1:gcc                    ########################################### [100%]
[root@RedHat9 mnt]#

現在查看一下gcc有沒有裝好：

[root@RedHat9 mnt]# rpm -qa gcc*
gcc-3.2.2-5
[root@RedHat9 mnt]#

gcc安裝成功
