[英]Upgrade from gcc 5.4 to gcc 6.3 std::thread std:ref issue
我最近從gcc 5.4升級到了gcc 6.3。 過去可以正常運行的C ++代碼停止了編譯，我沒有足夠的經驗來推斷出問題所在。
代碼位於我創建的對象中，該對象使用sfml生成窗口。 它實例化一個線程，該線程使用sfml :: Window指針根據指向視頻幀的外部設置的指針來更新圖像。
該代碼既簡單又基本，我在代碼的其他地方生成了線程（盡管不是對象的線程）。
以下是代碼片段：
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);
}
錯誤是在上面顯示的renderThread =行（錯誤輸出的第174行）上產生的，該錯誤又長又殘酷，說實話，當我嘗試理解它們時，我好像淹死了。 從什么時候開始c ++有元組？ 大聲笑。 我正在上班學習python，最后得到了一個元組，然后發生了這種情況...
我剛剛檢查了一下，它仍然可以在gcc 5.4上編譯和運行。
這些是錯誤，請注意，這只是前幾個錯誤，我不想向論壇發送垃圾郵件。

我有幾天完全相同的問題，當我讀到有關“線程”的結論時，我設法創建了一個測試項目，該項目在GCC 6.1.0中失敗，但在5.3.0上有效。
重要的是要注意，它在CUDA下編譯時會失敗，也就是說，啟動器是.cu文件。 如果將其編譯為.cpp文件，則可以通過在編譯過程中設置-pthread標志來解決問題。
因此，我現在正在使用5.3.0。 我在這里附加失敗的代碼。 導致失敗的軟件：

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;
}

}
return intAmount;
}

我不明白為什么它失敗了。 我可以向Nvidia或GCC發布錯誤嗎？
願您重現它並遇到任何麻煩，請隨時發表評論，我會幫助您！
最好的問候！
