此代码:
#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
