Как правильно создать поток thread с методом класса в c++?

Question

[Bratis4ka]

Не могу понять как мне создать поток.

Часть кода:

#include <thread>

std::shared_ptr<Admin::ServerManager> Admin::ServerManager::mServerManager = nullptr;
std::mutex Admin::ServerManager::mMutex{};

bool Admin::ServerManager::exec(commandType type)
{
    std::thread th(&ServerManager::start);
    switch (type)
    {
        case START:
            start();
            return true;

        case STOP:
            stop();
            return true;
//Some Code

void Admin::ServerManager::start()
{
    if(serverStatus == 0)
    {
        serverStatus = 1;
        Admin::ServerManager::Socket.reset(new Network::ServerSocket);
    }
    else
        std::cout << "The server is already up";
}

Ошибки, которые вылетают при билде:

У вас та же ошибка, что и в предыдущем вопросе. Старт - нестатическая функция, значит ей надо передавать указатель на this. Одно из решений

std::thread th(&ServerManager::start, this);

[cunion]

xorknown, Или же

std::thread th([this]()
{
 this->start();
});
