lambda表达式语法错误

Question

这段代码：

#include "Backpack.h"
#include <sstream>
#include <algorithm>

int Backpack::getCurrentWeight()
{
    int weight = 0;
    std::for_each(items.begin(),items.end(),[&](std::shared_ptr<PickupItem> item){ //8
        weight +=item->getWeight();
    });
    return weight;
}

生成这些错误：

Backpack.cpp: In member function 'int Backpack::getCurrentWeight()':
Backpack.cpp:8: error: expected primary-expression before '[' token
Backpack.cpp:8: error: expected primary-expression before ']' token
Backpack.cpp:8: error: expected primary-expression before 'item'

该项目建立在Linux上，但在Windows上却没有。 我的Qt版本：桌面Qt 4.7.4 - MinGW 4.4（Qt SDK）。 我添加了以下标志：QMAKE_CXXFLAGS + = -std = c ++ 0x

您的编译器不支持lambda表达式。
