Abstraction　

Red Hat Enterprise 5默認是不安裝gcc的，需要自己手動安裝。gcc所需要的包都可以在安裝光盤上找到，至于最新的gcc可以在?http://gcc.gnu.org/?下載，但是是以源碼的形式壓縮的，需要對其進行編譯。

Solution
　　1、插入安裝盤,首先在/mnt下創建cdrom文件夾，然后掛載安裝盤：mount /dev/cdrom /mnt/cdrom；

　　2、進入/mnt/cdrom/Server，按順序安裝以下包：

（1）安裝kernel-headers-2.6.18-128.el5.i386.rpm

[root@localhost Server]# rpm -ivh ./kernel-headers-2.6.18-128.el5.i386.rpm

warning: ./kernel-headers-2.6.18-128.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

1:kernel-headers ########################################### [100%]

（2）安裝glibc-headers-2.5-34.i386.rpm

[root@localhost Server]# rpm -ivh ./glibc-headers-2.5-34.i386.rpm

warning: ./glibc-headers-2.5-34.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

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

（3）安裝glibc-devel-2.5-34.i386.rpm

[root@localhost Server]# rpm -ivh ./glibc-devel-2.5-34.i386.rpm

warning: ./glibc-devel-2.5-34.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

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

（4）安裝libgomp-4.3.2-7.el5.i386.rpm

[root@localhost Server]# rpm -ivh ./libgomp-4.3.2-7.el5.i386.rpm

warning: ./libgomp-4.3.2-7.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

1:libgomp ########################################### [100%]

（5）安裝rpm -ivh gcc-4.1.2-44.el5.i386.rpm

[root@localhost Server]# rpm -ivh gcc-4.1.2-44.el5.i386.rpm

warning: gcc-4.1.2-44.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

1:gcc ########################################### [100%]

（6）安裝libstdc++-devel-4.1.2-44.el5.i386.rpm

[root@localhost Server]# rpm -ivh ./libstdc++-devel-4.1.2-44.el5.i386.rpm

warning: ./libstdc++-devel-4.1.2-44.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

1:libstdc++-devel ########################################### [100%]

（7）安裝gcc-c++-4.1.2-44.el5.i386.rpm

[root@localhost Server]# rpm -ivh ./gcc-c++-4.1.2-44.el5.i386.rpm

warning: ./gcc-c++-4.1.2-44.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

1:gcc-c++ ########################################### [100%]

?此過程中有可能需要安裝其他的安裝包，?如下：
[root@localhost Server]# rpm -ivh gcc-4.1.2-14.el5.i386.rpm?
warning: gcc-4.1.2-14.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
error: Failed dependencies:
??????? glibc-devel >= 2.2.90-12 is needed by gcc-4.1.2-14.el5.i386

找到相應的安裝包安裝即可

[root@localhost Server]# rpm -ivh gcc-4.1.2-14.el5.i386.rpm?
warning: gcc-4.1.2-14.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
error: Failed dependencies:
??????? glibc-devel >= 2.2.90-12 is needed by gcc-4.1.2-14.el5.i386
[root@localhost Server]# rpm -ivh glibc-devel-2.5-18.i386.rpm?
warning: glibc-devel-2.5-18.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
Preparing...??????????????? ########################################### [100%]
?? 1:glibc-devel??????????? ########################################### [100%]

3、最后進入/mnt，輸入rpm –qa gcc*?，如果成功安裝了gcc，可以查出以下內容：

binutils-2.13.90.0.18-9.i386.rpm

cpp-3.2.2-5.i386.rpm
