我正在尝试将其编译为嵌入式项目，但始终无法编译。在Mac上使用clang可以正确编译代码。
该示例基本上将2个线程添加到双端队列容器，将它们加入并从容器中删除。更新
class th {
public:
void func() {
sleep(3);
*this->progress = 100;
}
th(int* prog) :
progress(prog),
m_thread(std::thread(&th::func, this)) {};
th(th const& other) = delete;
th(th && other) = default;
th& operator=(th const& other) = delete;
th& operator=(th &&) = default;
void join() { m_thread.join(); }
int *progress;
private:
std::thread m_thread;
};
int main(void) {
std::vector<int> progress;
progress.push_back(-1);
progress.push_back(-1);
std::deque<std::unique_ptr<th>> deq;
std::cout << "progress[0]:" << progress[0] << std::endl;
std::cout << "progress[1]:" << progress[1] << std::endl;
std::cout << "executing threads..." << std::endl;
for(size_t i = 0; i < 2; ++i) {

最佳答案
问题是您的班级不可移动。我可以理解，由于该类具有std::thread，因此您希望避免默认的复制行为，但是我看不出该类不可移动的任何原因。如果启用移动构造和分配your code works fine。
th(th const& other) = delete;
th(th && other) = default;
th& operator=(th const& other) = delete;
th& operator=(th &&) = default;
我也会根据以下内容调整您构建这些对象的方式
for(size_t i = 0; i < 2; ++i) {
deq.push_back(std::make_unique<th>(&progress[i]));
}
