当我使用 TBB 库的 parallel_for 时出现错误。我不明白为什么..我已经能够使用 tbb::atomic 所以我猜这不是链接问题。这是我使用 tbb 的代码部分：

auto values = std::vector<double>(10);

    tbb::parallel_for( tbb::blocked_range<int>(0,values.size()),
                       [&](tbb::blocked_range<int> r)
    {
        for (int i=r.begin(); i<r.end(); ++i)
        {
            values[i] = std::sin(i * 0.001);
        }
    });

    double total = 0;

    for (double value : values)
    {
        total += value;
    }

    std::cout << total << std::endl;

我在网上举了一些例子，调试起来更方便。这是我的包含，我尝试添加 tbb::task 但它没有用。

#include "interval_map_estimator.h"
#include "interval_map_estimation.h"
#include <stdlib.h>
#include <boost/numeric/ublas/matrix.hpp>

//Antoine
#include <chrono>
#include <boost/thread/thread.hpp>
#include <tbb/parallel_for.h>
#include <tbb/task.h>
#include <iostream>

在我得到的两个错误中（它们是相同的）
