CentOS是在linux开发基础上的常用系统，然后我深入探讨了CentOS rpm安装，在这里对CentOS用户概括讲解下CentOS rpm安装应用，linux下使用CentOS rpm安装libxml2，gcc,gcc-c++等基本包 我使用了的linux版本是CentOS5.0,进行了最小安装，所以很多包都没有安装上。比如gcc (C组件和解释器),libxml2,gcc-c++等。我现使用安装光盘安装这些所需的包。之前我已经安装过gcc了，没有记下这个安装时的步骤，不过跟其它的安装是一样的。现记下我的安装时的日记，以备后忘。希望对网友们也会有点帮助

CentOS rpm安装libxml2-devel

CentOSrpm安装libxml2-devel时提示其依赖的包还有pkgconfig-0.21-1,zlib-devel-1.2.3-3,所以按其提示缺少什么包就在CentOS rpm安装光盘上找什么包。一般基本的包在光盘上都会有放入第2张光盘[root@localhost mnt]# mount /dev/cdrom /mnt/cdrommount: block device /dev/cdrom is write-protected, mounting read-only[root@localhost mnt]# find -iname pkgconfig*./cdrom/CentOS/pkgconfig-0.21-1.fc6.i386.rpm[root@localhost mnt]# rpm -ivh ./cdrom/CentOS/pkgconfig-0.21-1.fc6.i386.rpmwarning: ./cdrom/CentOS/pkgconfig-0.21-1.fc6.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897Preparing...

[root@localhost mnt]# umount /mnt/cdrom

放入第3张光盘[root@localhost mnt]# find -iname zlib*./cdrom/CentOS/zlib-devel-1.2.3-3.i386.rpm[root@localhost mnt]# rpm -ivh ./cdrom/CentOS/zlib-devel-1.2.3-3.i386.rpm[root@localhost mnt]# find -iname libxml*./cdrom/CentOS/libxml2-devel-2.6.26-2.1.2.i386.rpm[root@localhost mnt]# rpm -ivh ./cdrom/CentOS/libxml2-devel-2.6.26-2.1.2.i386.rpm

CentOS rpm安装gcc-c++

出现错误configure: error: C++ preprocessor "/lib/cpp" fails sanity checkSee `config.log' for more details.gcc没有安装全,缺少c++预处理程序等还有
