VS2019使用VLD(Visual Leak Detector)检测CPP内存泄漏

环境：

编译器: VS2019
VLD: 2.5.1

前言

在windows平台下，VLD(Visual Leak Detector)是一个比较准确的内存泄漏检测工具，支持输出检测报告。
下载地址：https://github.com/KindDragon/vld

1. 安装

下载路径：

https://github.com/KindDragon/vld/releases/download/v2.5.1/vld-2.5.1-setup.exe

双击安装即可

2. 编写测试代码

• main.cpp

#include "vld.h"
int main()
{
    char *s = new char[1024];
    return 0;
}

• CMakeLists.txt

cmake_minimum_required(VERSION 2.8.12)

project(main)

# release enable vld
add_definitions(-DVLD_FORCE_ENABLE)
# set vld include and lib
SET(VLD_PATH "C:/Program Files (x86)/Visual Leak Detector")
SET(VLD_INCLUDE "${VLD_PATH}/include")
SET(VLD_LIB "${VLD_PATH}/lib/Win64/vld.lib")

add_executable( ${PROJECT_NAME} main.cpp)

• 编译为64位RelWithDebInfo

cmake -B bin -Thost=x64
cmake --build bin --config=RelWithDebInfo

3. 结果

main.exe
Visual Leak Detector read settings from: C:\Program Files (x86)\Visual Leak Detector\vld.ini
Visual Leak Detector Version 2.5.1 installed.

4. 其他

4.1 报告输出到文件

复制C:\Program Files (x86)\Visual Leak Detector\vld.ini文件到main.exe所在目录

修改vld.ini中的ReportTo = debugger为ReportTo = both

然后运行main.exe会同时输出信息到控制台和memory_leak_report.txt文件

4.2 输出指定名称的报告文件

VLDSetReportOptions(VLD_OPT_REPORT_TO_FILE,L"main.txt");
