Error: qt 'iostream' file not found

  • Hello.
    I'm having an issue with QT on Ubuntu 18.04 and win10.

    When I start a New Project under the Welcome tab, under Non-QT Project, Plain C++ Application I get errors with all my #include statements. The project starts with "#include <iostream>" which the program attaches an error to.

    Can anyone tell me what's the problem and how do I solve it?

    Does other types of project works ?
    Like a Qt GUI application?

    Most likely something wrong with your compiler kit but its odd you get this in
    both Win and Linux..

    What Qt version did you download and install ?

    hi @rovguy,

    • which Creator version is that?
    • can you actually compile your app?
