Valgrind是一款用于内存调试、内存泄漏检测以及性能分析的软件开发工具。
Valgrind遵守GNU通用公共许可证条款,是一款自由软件。
到3.3.0版本为止,Valgrind支持x86、x86-64以及PowerPC上的Linux。除此之外,还有一些其它非正式支持的类Unix平台(如FreeBSD、NetBSD以及Mac OS X)。
1、下载Valgrind 3.11.0
直接下载源码包
wget http://valgrind.org/downloads/valgrind-3.11.0.tar.bz2
tar -xjvf valgrind-3.11.0.tar.bz2
cd valgrind-3.11.0/
使用svn克隆一个
svn co svn://svn.valgrind.org/valgrind/trunk valgrind
2、生成Makefile并使用它进行编译
生成Makefile
的步骤在README
这个文件中有写。
- 运行
./autogen.sh
来设置环境(你需要标准的autoconf
工具)
这个脚本其实是调用的aclocal
autoheader
automake
autoconf
,所以必须先安装好它,如果没有安装,在运行这个脚本的时候会提示你的。
- 运行
./configure
来生成Makefile
文件
这里你可以使用./configure --help
来查看可以使用哪些参数设置。
一般设置好安装路径即可./configure --prefix=/usr/local/valgrind
- 运行
make
进行编译,运行make install
进行安装。
3、测试一下编译完成之后可以测试一下。
因为上面编译安装的时候指定了安装目录,所以还需要把valgrind
的bin
目录路径添加到环境变量PATH
中。否则只能使用全路径来运行valgrind
这里我把它写入到~/.bashrc
文件中。打开~/.bashrc
文件,然后在最后添加一行PATH=${PATH}:/usr/local/valgrind/bin
,之后使用source ~/.bashrc
来更新一下。
真的测试一下哦(这是README里面给出的测试命令)

自己写一个内存访问越界和泄露的小例子来测试一下
#include <stdlib.h>intmain()
{
((char*)malloc(10))[10] =100;return0;
}
使用下面的命令来检查
valgrind --track-fds=yes --leak-check=full --undef-value-errors=yes ./test
检查结果
