multithreading - 无法将参数传递给 std::thread？

Question

我正在尝试使用 std::thread。正如许多示例所示，我的线程应该调用一个方法并将 struct 作为参数传递。除了我非常简单的代码不会编译。作为记录，我知道 this问题，但似乎没有任何帮助。

我在哪里调用线程:

void Exporter::save() const {
    thread(write_to_disk, this->parameter).detach();
}

write_to_disk 的签名:

void write_to_disk(const Parameter& parameter)

write_to_disk 在 .cpp 文件的无名命名空间中定义。

我收到以下错误:

src/Exporter.cpp:65:5: error: no matching constructor for initialization of 'std::__1::thread'
    thread(write_to_disk, this->parameter).detach();

如果我这样做对我来说很好

clang++ -std=c++11 test.cpp
