卸载原有GDB

 

１. 查询　ｇｄｂ是否安装

[root@test01~]# rpm -qa |grep gdb

gdb-7.0.1-37.el5_7.1

gdbm-1.8.0-26.2.1

２.　删除包

rpm-e --nodeps gdb-7.0.1-37.el5_7.1

 

注：

rpm -qa 后面要跟上包的名字才能搜索到
比如，rpm-qa http 搜不到，是因为包的名字叫做 httpd
rpm-qa | grep 是把搜索到的全部包的名字交给 grep 去过滤，只要包含那个字符串就会被显示出来

 

安装新版本GDB

 

１.获获取gdb-7.2.tar.gz版本安装包 

如果为gdb-7.2.tar.gz形式的则用 

[root@localhost]# tar –xvzf gdb-7.2.tar.gz 

２.　 安装执行步骤 

基本上所有的源码包都是三步，configure，make，make install。 进入gdb解压后的目录，按顺序执行以下命令： 

[root@test01gdb-7.2]#./configure 

[root@test01gdb-7.2]#make 

[root@test01gdb-7.2]#make instal

[root@test01gdb-7.2]# cp gdb/gdb /usr/bin

查看gdb版本

[root@test01 gdb-7.2]# gdb
