I'm trying to use std::thread
. My thread is supposed to call a method and pass a struct
as a parameter, as so many examples show. Except my very simple code won't compile. For the record, I'm aware of this question but nothing there seems to help me.
Where I call the thread:
void Exporter::save() const {
thread(write_to_disk, this->parameter).detach();
}
The signature of write_to_disk
:
void write_to_disk(const Parameter& parameter)
write_to_disk
is defined in a nameless namespace in the .cpp
file.
I get the following error:
src/Exporter.cpp:65:5: error: no matching constructor for initialization of 'std::__1::thread'
thread(write_to_disk, this->parameter).detach();

Works fine for me if I do
clang++ -std=c++11 test.cpp
