Having trouble making a thread for a member function with parameters | C++ | WxWidgets

Question

My thread gives me no errors before compilation, but upon compilation, I get this error...

Error code:

This is despite following the solution provided in this question. Although the difference here is that I have multiple parameters and I'm starting the thread inside another member function.

I've looked at online resources and haven't turned up anything, if anyone can help that would be great.

Code:

class MyFrame : public wxFrame{
    public:
        MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size);
        
        

    private:
void RightSearchBarTextChange(wxCommandEvent& event);
void RightSearchResultsCreate(std::vector<std::string> CategoryFilterMap, std::vector<std::string> SubCategoryFilterMap, std::vector<std::variant<std::string, std::vector<std::string>>> DateFilterMap, std::vector<std::string> TagFilterMap);
}

void MyFrame::RightSearchBarTextChange(wxCommandEvent& event) {
std::thread thread_object(&MyFrame::RightSearchResultsCreate, RightSearchCategoryFilterSelectedVector, RightSearchSubCategoryFilterSelectedVector, RightSearchDateFilterSelectedVector, RightSearchTagFilterSelectedVector);
    thread_object.join();

}

void MyFrame::RightSearchResultsCreate(std::vector<std::string> CategoryFilterMap, std::vector<std::string> SubCategoryFilterMap, std::vector<std::variant<std::string, std::vector<std::string>>> DateFilterMap, std::vector<std::string> TagFilterMap) {

// do stuff here

}

It's hard to say without a [mcve], but it appears you're not passing an object to your `thread`: It should look like `std::thread thread_object(&MyFrame::RightSearchResultsCreate, this, ...);` (or simply use a lambda) — Tas, Aug 10 '22 at 03:26
Learn about std::async and lambda functions. https://en.cppreference.com/w/cpp/thread/async, https://www.learncpp.com/cpp-tutorial/introduction-to-lambdas-anonymous-functions/. By making the future a member you can ensure the thread will stop at object destruction. If you make it the first member you will ensure the thread can acces all members until it is (finished and) destroyed.
