Linux 下用 valgrind 查找内存泄漏小例子

1.安装 valgrind

　　yum install valgrind

2.测试用例

main.cpp

#include <iostream>

using namespace std;

struct StockInfo
{
    int iMarket;
    string sCode;
    
    StockInfo()
    : iMarket(0)
    {
    }
};

int main()
{
    StockInfo *pStockInfo = new StockInfo;
    pStockInfo->iMarket = 1;
    pStockInfo->sCode = "000001";
    cout << "Market:" << pStockInfo->iMarket << "|" << "Code:" << pStockInfo->sCode << endl;
    
    //delete pStockInfo;
    return 0;
}

makefile

TARGET=main

INC=
LIB_PATH=
LIB=

CFLAGS:=-Wall -g -O0 -lrt -rdynamic -fPIC -Wl,-rpath=./ $(INC) $(LIB_PATH)
CPPFLAGS:=$(CFLAGS)

SRC=$(shell echo *.cpp)
OBJ=$(patsubst %.cpp,%.o,$(SRC))

all: $(TARGET)

$(TARGET): $(OBJ)
	$(CXX) $^ $(CFLAGS) $(LIB) -o $@

clean:
	rm -f $(OBJ)
	rm -f $(TARGET)

make 编译生成可执行文件：
