    hi,
    I'm starting to code with qt and firebird
    I decided to use IBPP for connecting qt application with firebird db on windows 10
    after including ibpp.h in my project and after trying to build it I get the following errors:
    error1:
    C:\Users\jozol\OneDrive\APP-DEMO\qtFB\ibpp-core\ibpp.h:875: error: undefined reference to `IBPP::DatabaseFactory(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'

    error2:
    collect2.exe:-1: error: error: ld returned 1 exit status
    could you please help me on this?
    thanks

      Did you include de LIB in your .pro?

      
      win32{
        LIBS += -L<path to lib> -lfbclient_ms -ladvapi32
        DEFINES += IBPP_WINDOWS
      }

          Hi and welcome to devnet,

          You should post the actual error, this is just the end of the log and not the most useful information can be extracted from that part.

            Hi,
            This is how my .pro file looks now.
            It compiles...

              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

                      For which version of MSVC are your Firebrid libraries compiled ?

                      What about ib_util_ms.lib ?

                        Hi, I reinstalled Qt with MinGW, included ib_util_ms.lib and error looks like this:

                        When I comment this line in .cpp file
                        // db=IBPP::DatabaseFactory(serverName,dbName,userName, password);
                        no error occures...
                        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...
                        Regards.

                          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.

                            @SGaist
                            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.
