Обновление с gcc 5.4 до gcc 6.3 std :: thread std: ref проблема
Я недавно обновился до gcc 6.3 с gcc 5.4. Код C ++, который раньше просто компилировался и запускался, прекратил компиляцию, и я не достаточно опытен, чтобы понять, что происходит не так.
Код находится в объекте, который я создал для порождения окон с помощью sfml. Он создает поток, который использует указатель sfml :: Window для обновления изображения на основе установленного извне указателя на видеокадр.
Код является основным и простым, и я порождаю потоки в другом месте кода (хотя не потоки объекта).
Вот фрагменты кода:
class owindow
{
public:
...
private:
...
std::thread renderThread;
...
void windowRender(void);
...
};
owindow::owindow(std::string name, win_t type, int width, int height, uint32_t *image)
: renderThread()
{
typ = type;
wid = width;
hei = height;
nam = name;
frame = image;
resizewin = false;
killthread = false;
...
window = new sf::Window(sf::VideoMode(windowwidth, windowheight), name.c_str(), sf::Style::Default, settings);
window->setVerticalSyncEnabled(false);
...
void owindow::start(void)
{
// Start the render thread.
renderThread = std::thread(&owindow::windowRender, this);
}
Ошибки генерируются в строке renderThread =, показанной выше (строка 174, в выводе ошибок), длинные и жестокие, и, честно говоря, я чувствую, что тону, когда пытаюсь их понять. С каких это пор у c ++ есть кортежи? ЛОЛ. Я изучаю Python на работе и, наконец, получил, что такое кортеж, а потом у меня это случилось …
Я только что проверил, он все еще компилируется и работает с gcc 5.4.
Вот ошибки, обратите внимание, что это только первые несколько ошибок, я не хотел спамить на форуме.

Решение
У меня была точно такая же проблема в течение нескольких дней, и когда я прочитал ваши выводы по «темам», мне удалось создать тестовый проект, который не работает в GCC 6.1.0, но работает на 5.3.0.
Важно отметить, что это не удается при компиляции под CUDA, то есть Launcher — это файл .cu. Если вы скомпилируете его как файл .cpp, проблема будет устранена путем установки флага -pthread в процессе компиляции.
Я сейчас работаю с 5.3.0 из-за этого. Я прилагаю здесь код, который не удается. Программное обеспечение, используемое, чтобы это терпело неудачу:
CMake 10, ниндзя, GCC 6.3.0, CUDA 9.0.176
Ракета-носитель:
#include "ClassWithT/Functions.hpp"#include <stdlib.h>
#include <iostream>
int main()
{
int* m = (int*)malloc(2 * sizeof(int));
float* n = (float*)malloc(2 * sizeof(float));
m[0] = 5;
m[1] = 6;
n[0] = 2.5f;
n[1] = 5.6f;
Functions<int>* f = new Functions<int>(m, 2, 0);
std::cout << f->ManagingFutures() << std::endl;
Functions<float>* g = new Functions<float>(n, 2, 0);
std::cout << g->ManagingFutures() << std::endl;
return 0;
}
Functions.ipp:
#pragma once
#include "Functions.hpp"
template<class T>

valuesList = list;
numberOfValuesInList = numValues;

{

}

}
return intAmount;
}
template<class T>

testThread = std::async(std::launch::async, &Functions::DoSomeStuff, this);
return testThread.get();

T ManagingFutures();

};
#include "Functions.ipp"
#endif
Я не понимаю, почему это не удается. Могу ли я выдать ошибку в Nvidia или GCC?
Если вы хотите воспроизвести это и получить какие-либо проблемы, не стесняйтесь комментировать, я помогу вам!
С наилучшими пожеланиями, ребята!
