    @wwwsharq you might consider to use a plain c++ or c project with Qt instead of trying projects with Qt Widgets

    @Ronel_qtmaster please stop posting useless stuff. What has your answer to do with the problem?

      @JonB hey, thank you for your response i have recently started to learn qt so i don't yet know it as well as i know winsock, can you specify what kind of like i should add to cmake (that's what i got from your comment at least) and/or how i would go about substituting this in qt?

        do you know what lines i'd have to add? honestly i've messed with the cmake file alot an i've had no luck

            This is a cmake configuration error. Either you don't have WindowsSDK installed or it doesn't provide a cmake module for what you requested, or you have not pointed to cmake to find said module.

            Read and abide by the Qt Code of Conduct

                  @Christian-Ehrlicher hello do you have a tutorial or site you would reccomend to learn what you just said that isn't the cmake website? i have not understood evrything there and saying add target_link_libraries call doesn't tell me much i have added that line plenty of times without any luck, just more errors

                  target_link_libraries(eccoci PRIVATE ws2_32)
                  

                  and the like i've tried already

                        add_executable(Executive ${exec_src})

                        You create a library but don't link it to your executable.
                        Also you link the QtWidgets library private to your library which is wrong (as you expose QtWidgets stuff in your library to it's users). So either properly link public or link your executable also to QtWidgets.

                          If you're using visual studio (and cl) by far the easiest way is to

                          # pragma comment(lib, "ws2_32.lib")
                          

                          the less you need to mess with CMake or (build files in general) the better.

                            Using some non-standard stuff instead standarized scripting is for sure much better.
                            If you would have read the post from above you would see that the OP is using MinGW which does not support this crap.

                              Nothing standard about "scripting" (which I believe you use to refer to CMake) . But yeah, some of us prefer to have things the easy way and some don't...

                                  You should try to rearrange your header files.

                                  Try the following way which is i used.

                                  #define WIN32_LEAN_AND_MEAN

                                    @Ketan__Patel__0011
                                    Have you verified these #pragma comment (lib, ... statements work from MinGW? They are not just an MSVC thing?

                                    Maybe your re-ordering of the headers will help, I don't know, but I don't see how this will solve MinGW not knowing to link with Ws2_32, which seems to be the error message.

                                    Same sort of thing as @SamiV123 above. Don't forget the OP actually already has

                                     #pragma comment(lib, "Ws2_32.lib")
                                    

                                    in his original code question, and it's still not linking....

                                      @Ketan__Patel__0011
                                      Have you verified these #pragma comment (lib, ... statements work from MinGW? They are not just an MSVC thing?

                                      Maybe your re-ordering of the headers will help, I don't know, but I don't see how this will solve MinGW not knowing to link with Ws2_32, which seems to be the error message.

                                      Same sort of thing as @SamiV123 above. Don't forget the OP actually already has

                                       #pragma comment(lib, "Ws2_32.lib")
                                      

                                      in his original code question, and it's still not linking....

                                      @JonB said in error: undefined reference to `__imp_WSAStartup':

                                      They are not just an MSVC thing

                                      The pragma is proprietary MSVC crap

                                        @Christian-Ehrlicher I know. I was inviting @Ketan__Patel__0011 to consider his answer for the OP with MinGW in this light.

                                          Using MingW on Windows when MSVS is free (and is essentially the de-facto standard C++ tool for Windows) is just bonkers.
