QT中的检测内存泄露

QT中的检测内存泄露 ，在WINDOWS下面检测

工具：vld-2.3-setup.exe  http://vld.codeplex.com/downloads/get/670164

.pro中的代码如下：

#-------------------------------------------------

#-------------------------------------------------

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = tabdialog
TEMPLATE = app


SOURCES += main.cpp\
#        mainwindow.cpp\
tabdialog.cpp

#HEADERS  += mainwindow.h
HEADERS  += tabdialog.h

#FORMS    += mainwindow.ui

#QT += widgets

#HEADERS       = tabdialog.h \
#    tabdialog.h
#SOURCES       = main.cpp \
#                tabdialog.cpp \
#    tabdialog.cpp

## install
#target.path = $$[QT_INSTALL_EXAMPLES]/widgets/dialogs/tabdialog
#INSTALLS += target

#wince50standard-x86-msvc2005: LIBS += libcmt.lib corelibc.lib ole32.lib oleaut32.lib uuid.lib commctrl.lib coredll.lib winsock.lib ws2.lib


win32
{
}
DEFINES += _DEBUG
        VLD_PATH = C:/Program Files (x86)/Visual Leak Detector
        INCLUDEPATH += $VLD_PATH/include
        #LIBS += -L $$VLD_PATH/lib/Win32 -lvld
        #LIBS += -L $$VLD_PATH/lib/Win32
#LIBS +=  -L C:/Program Files (x86)/Visual Leak Detector/lib/Win32/vld
#LIBS += -Lvld
LIBS += -LC:/Program Files (x86)/Visual Leak Detector/lib/Win32/-lvld
#LIBS+=  -lvld #
        #LIBS += -L $VLD_PATH/lib/Win32/vld.lib

#win32 {
#    CONFIG(debug, debug|release)
#    {
##        DEFINES += _DEBUG
#        # vld 2.2 downloaded from http://vld.codeplex.com/  C:\Program Files (x86)\Visual Leak Detector\include
#        VLD_PATH = C:/Program Files (x86)/Visual Leak Detector
#        INCLUDEPATH += $VLD_PATH/include
#        LIBS += -L$VLD_PATH/lib/Win32 -lvld
#    }
#}

在main.cpp中写如下：

<pre style="margin-top: 0px; margin-bottom: 0px;"><span style=" color:#409090;">#ifdef</span><span style=" color:#646482;"> </span><span style=" color:#409090;">_DEBUG</span>

#ifdef _DEBUG

#include "vld.h"

#endif

int *pint =NULL;
    pint=new int[30];

    int *pint1 =NULL;
    pint1=new int[30];

效果如图：

其中还要在环境变量中添加如下：

Path: C:\Program Files (x86)\Visual Leak Detector\bin;

如果在.PRO中出现如下图：

无法打开，一要检查你的PRO中的LIB的路径，二要检查你是否把此LIB放在DEBUG中，如下图所示：
