Question

我试图使用std::thread。我的线程应该调用一个方法并传递一个struct作为参数，正如许多例子所示。除了我非常简单的代码不会编译。为了记录，我知道this问题，但似乎没有任何帮助我。

我在哪里打电话：

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文件中的无名空间中定义。

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，对我来说没问题

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

无法将参数传递给std :: thread？
