安裝編譯步驟：

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

新增至環境變數：

sudo gedit ~/.bashrc

新增：

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

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

source .bashrc

檢測是否成功編譯：

valgrind --version

測試用例：

#include <stdlib.h>

int main()

{

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

pArray[5] = 1;

int * pInt ;

int x = *pInt;

* pInt = 2;

return 0;

}

編譯：gcc -g -o test main.c

檢測：valgrind --leak-check=yes ./test

檢測32位程式的時候需要安裝對應的i386庫否則會提示錯誤：
