linux的pvtrace环境配置
1.查看当前ubuntu版本号
froid@ubuntu:~/Desktop$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 10.04 LTS
Release: 10.04
Codename: lucid
2.如何终止ping
ctrl+c
3.linux修改文件访问权限
chmod 777 文件名
chmod -R 777 文件名 【注意是R,不是r】
参考:http://blog.csdn.net/chenjiiinliang/article/details/7288173
删除文件夹及其子文件
rm -rf 文件夹名
4.ubuntu更换软件源
/etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu/ precise main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ precise-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ precise-proposed main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ precise-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ precise main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ precise-security main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ precise-proposed main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ precise-backports main restricted universe multiverse
5.安装pvtrace和graphviz工具:
$ sudo apt-get install graphviz
$wget http://public.dhe.ibm.com/software/dw/library/l-graphvis/pvtrace.zip
$unzip pvtrace.zip –d pvtrace
$cd pvtrace
$make
$make install
------------------------------------------------------------------------------------------------------------11.06晚追加
6.打开终端快捷键 ctrl+alt+t
7.Ubuntu忘记root密码
Ubuntu的root默认是禁止使用的,在安装的时候也没要求你设置root的密码,和红帽系统系列这里是不同的。
要在Ubuntu下使用root,我们可以使用终端给root设置密码sudo passwd root
-------------------------------------------------------------------------------------------------------------11.30下午追加
8.VMware Workstation 11序列号:1F04Z-6D111-7Z029-AV0Q4-3AEH8
9.安装pvtrace:将压缩包拖入ubuntu,Extract Here,make,make install
安装graphviz:sudo apt-get install graphviz,网址http://www.graphviz.org/Download..php
追踪cflow:将压缩包拖入ubuntu,Extract Here,cd Desktop/cflow-1.1/,配置./configure,修改src下的makefile
搜索posix.$(OBJEXT) 在其后加入 instrument.$(OBJEXT)
搜索CFLAGS = -g 将其后改为 -finstrument-functions
修改这个参数的作用是在程序中加入hook 使得在每次程序进入和退出时分别调用两个函数enter 和exit 获得函数地址
搜索posix.c,在其后加入\ 换行加入instrument.c
然后将pvtrace文件夹下的insrtument.c复制到cflow的src文件夹下
在目录cflow-1.1下 make,make install【如果权限不够,切换到root用户】
cd src,使用cflow追一个文件,如cflow rc.c 生成trace.txt (函数进入和退出的地址,示例如下)
E0x804a56c
E0x805053e
X0x805053e
E0x805053e
X0x805053e
E0x804aa14
pvtrace cflow 则在src目录下生成graph.dot文件
dot -Tpng graph.dot -o graph.png 生成graph.dot文件和图像graph.png
