    @SGaist
    I removed the first line.
    But the second line is half incomplete! Add what to what?

      @tomy Just add the line as @SGaist wrote. This will add no Qt modules, not even core.

      Qt has to stay free or it will die.

        Here is .pro file:

        TEMPLATE = app
        CONFIG += console c++11
        CONFIG -= app_bundle
        QT =
        SOURCES += \
                main.cpp
        

        Still the same errors!

          Did you re-run qmake after modifying the .pro file ?

            If using qmake in Linux (Ubuntu) is this way, I did and below is the output. My project is on the Desktop named "hello_world".

              What do you get if you call make after that ?

                Do you mean I type "make" on the last line?

                      Thanks. I did it and it showed the output I wanted on the Terminal.
                      But still I see the errors and red lines on the code! :(

                      Why while the program runs successfully does Qt Qreator show them? And how to get rid of them. They are ugly indeed.

                        Try changing the code model used by Qt Creator.

                          @tomy said in My first console C++ program on Qt Creator:

                          Of course. I get 6 issues. 5 of them are errors and one warning, as shown in the screenshot in the first post here.

                          The screenshot in your first post shows errors and warnings from the static code analyzer, not from your compiler. We can tell because the red circle and yellow triangles are "hollow". Errors and warnings from your compiler have "filled" circles and triangles.

                          Try to build and run your code to activate your compiler. Does it run successfully?

                          Anyway, you are seeing these errors because the static code analyzer thinks you are writing C code (not C++ code) for some reason. You can disable it by clicking Help > About Plugins... and unchecking C++ > Clang Code Model

                          I believe @SGaist meant running qmake from within Qt Creator, when your project is open. The menu item is Build > Run qmake.

                          Running qmake in the console does not change anything in Qt Creator.

                                Thanks so much. It removed the majority of the red underlines.
                                Only two lines remain!

                                One more thing: Why does the IDE think I'm C coding while I explicitly told it by choosing "plain C++" that I would be coding on C++?

                                  I don't know. It works fine for me on Windows.

                                  It might be related to your Kit settings (this is just a guess).

                                      Hi! I think the problem is with your compiler, try setting it as g++ not gcc.

                                      For example, using MinGW on Windows (compiler path is ....\g++.exe):

                                        Unfortunately, I don't have a Linux machine with a recent version of Qt and Qt Creator.

                                        One thing you could try is to create a Qt Console Application, then remove Qt from the .pro file.

                                          Hi! I think the problem is with your compiler, try setting it as g++ not gcc.

                                          For example, using MinGW on Windows (compiler path is ....\g++.exe):

                                          Is it on Linux, please?
                                          The options are different between Windows and Linux.
