Qt Creator 安装 VLD
一、环境说明
1、VLD 内存检测工具，只能检测使用VC++编译器，不能用于检测MinGW编译器
所以要检测 Qt内存泄露问题编译器一定要是MSVC。
环境要求：
1、VLD 版本要2.X以上 不能使用1.X的版本。否则检测不准确，Qt检测会提示很多内存泄露。（本人使用vld-2.3-setup.exe）
2、VC++编译器 即MSVC 如果有安装VS则就有这编译器
D:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat
二、下载VLD
（1） http://vld.codeplex.com/releases
（2）
三、安装VLD
双击 vld-2.3-setup.exe
安装过程会弹出如下对话框，
选择是
安装完成
本人安装的路径是 D:\VLD
新的版本解决了path问题，所以我们无需做过多的设置
四、配置Qt Creator
在 工具->选项
构建和运行 --> 编译器
是否有vc++编译器 MSVC 如果没有 点击添加
构建和运行 --> 构建套件（Kit）
编译器选择
配置完成
五、VLD使用
1、创建测试项目：使用QtCreator创建一个Qt GUI项目
修改.pro文件，添加如下内容：
win32{
CONFIG(debug, debug|release) {
INCLUDEPATH += D:/VLD/include
DEPENDPATH += D:/VLD/include
LIBS += -LD:/VLD/lib/Win32 -lvld
}
}
注：D:/VLD 为本人安装的路径
2、在main函数上面添加以下代码：
#ifdef _DEBUG
#include "vld.h"
#endif
六、测试
#include "widget.h"
#include
#ifdef _DEBUG
#include "vld.h"
#endif
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Widget w;
w.show();
Widget *pWid= new Widget;
//delete pWid;
return a.exec();
}
测试结果：
Visual Leak Detector Version 2.3 installed.
