（Ubuntu64）valgrind安装+编译64位 32位版本

安装编译步骤：

wget http://valgrind.org/downloads/valgrind-3.12.0.tar.bz2

 

tar xvf valgrind-3.12.0.tar.bz2

 

cd valgrind-3.12.0

 

sudo apt-get install automake

 

./autogen.sh

 

./configure --prefix=/<pathto>/valgrind-3.12.0

 

make

 

make install

 

添加至环境变量：

sudo gedit ~/.bashrc

添加：

export PATH=$PATH:/<pathto>/valgrind-3.12.0/bin

export VALGRIND_LIB="/<pathto>/valgrind-3.12.0/lib/valgrind"

source .bashrc

检测是否成功编译：

valgrind --version

测试用例：

#include <stdlib.h>

int main()

{

int * pArray =malloc(sizeof(int) * 5);

pArray[5] = 1;

int * pInt ;

int x = *pInt;

* pInt = 2;

return 0;

}

编译：gcc -g -o test main.c

检测：valgrind --leak-check=yes ./test

检测32位程序的时候需要安装对应的i386库否则会提示错误：
