如何使用英特尔 TBB 并发无序列图

以下是我用来开始学习如何使用Intel TBB中的concurrent容器的代码。

代码只是尝试填充tbb::concurrent_unordered_map。

我已经使用以下命令在 Ubuntu 上安装了Intel TBB： sudo apt-get install libtbb-dev

但是，当我将代码编译为： g++ -std=c++11 -fopenmp -ltbb concur_hash.cpp

#include <iostream>
#include <vector>
#include <omp.h>
#include "tbb/concurrent_unordered_map.h"
int main() {
    tbb::concurrent_unordered_map<int, int> ht;
    std::vector<std::pair<int, int>> vec;
    vec.push_back({1,1});
    vec.push_back({1,9});
    vec.push_back({2,1});
    vec.push_back({2,2});
    vec.push_back({2,7});
    vec.push_back({3,0});
    vec.push_back({3,0});
    vec.push_back({3,0});
    vec.push_back({3,0});
    vec.push_back({3,10});
    const int vec_size = vec.size();

    #pragma omp parallel for
    for (int i = 0; i < vec_size; ++i) {
        auto it = ht.find(vec[i].first); 
        if (it != ht.end()) {
            it->second += vec[i].second;
        }   
        else { ht.insert(vec[i]); }
    }
    for (auto kv : ht) {
        std::cout << "k: " << kv.first << "t v: " << kv.second << std::endl;
    }
    return 1;
}

它抛出以下错误，我无法理解。
