    Which version of Qt are you using ? If above or equal 5.7, you can safely remove the C++XX config values. A C++11 able compiler is mandatory since 5.7. qmake should choose the latest standard available.

    And again, please post a more complete error log.

      I'm using qt 5.8
      Here is the content of .cpp, .h and .pro files, and text of error:
      //qt pro file

      The following define makes your compiler emit warnings if you use

      any feature of Qt which as been marked as deprecated (the exact warnings

      depend on your compiler). Please consult the documentation of the

      deprecated API in order to know how to port your code away from it.

      DEFINES += QT_DEPRECATED_WARNINGS

      You can also make your code fail to compile if you use deprecated APIs.

      In order to do so, uncomment the following line.

      You can also select to disable deprecated APIs only up to a certain version of Qt.

      #DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0

        Are you sure you are linking to all the required libraries ?

            For which version of MSVC are your Firebrid libraries compiled ?

            What about ib_util_ms.lib ?

              I really don't know what to do...I read on internet that this could be encoding problem, but I'm newb and it is little bit complex for me...

                Again: which compiler was used to build your IBPP libraries ? It's really important on Windows since you can't mix and match compilers. Only VS2017 is compatible with VS2015.

                  Where can I see that?
                  I'm including only ibpp.h file in my project, no ibpp library file.

                    Check the content of your package, README file etc. You can run Dependency Walker.

                      Checking the ZIP file contentes from https://www.firebirdsql.org/en/firebird-3-0-2/. Firebird is using MS compiler.

                      So, do not use MingW.
