1.查看当前gdb安装情况

[root@localhost core]# rpm -qa | grep gdb
gdbm-1.8.0-36.el6.x86_64
gdbm-devel-1.8.0-36.el6.x86_64
eggdbus-0.6-3.el6.x86_64
gdb-7.2-60.el6_4.1.x86_64

2.删除当前gdb版本

[root@localhost core]# rpm -e --nodeps gdb-7.2-60.el6_4.1.x86_64

3.下载最新gdb文件

[root@localhost core]# wget http://ftp.gnu.org/gnu/gdb/gdb-7.12.tar.gz

4.解压并cd到gdb目录

[root@localhost core]# tar -zxvf gdb-7.12.tar.gz

[root@localhost core]# cd gdb-7.12/

[root@localhost gdb-7.12]# ls
bfd config-ml.in COPYING depcomp install-sh ltgcc.m4 ltversion.m4 md5.sum opcodes src-release.sh
ChangeLog config.rpath COPYING3 djunpack.bat intl ltmain.sh MAINTAINERS missing readline symlink-tree

config.guess configure.ac cpu include libtool.m4 ltsugar.m4 Makefile.tpl move-if-change sim zlib

5.执行./configure脚本

[root@localhost gdb-7.12]# ./configure

6.编译

[root@localhost gdb-7.12]# make

7.make install

[root@localhost gdb-7.12]# make install

报错如下：

WARNING: 'makeinfo' is missing on your system.
You should only need it if you modified a '.texi' file, or
any other file indirectly affecting the aspect of the manual.
You might want to install the Texinfo package:
http://www.gnu.org/software/texinfo/
The spurious makeinfo call might also be the consequence of
using a buggy 'make' (AIX, DU, IRIX), in which case you might
want to install GNU make:
http://www.gnu.org/software/make/
make[5]: *** [gdb.info] Error 127

解决方法：

yum install texinfo

重新make instal

8.拷贝编译好的gdb到指定路径

[root@localhost gdb-7.12]# cp gdb/gdb /usr/bin/gdb

9.查看gdb版本

[root@localhost gdb-7.12]# gdb -v
