    @Toruha What compiler do you use for your Qt application?

      @Toruha I hope this is what you were asking.

        I'm trying to add a library to a project. https://github.com/AlexanderVatov/DuckX. Using qmake.
        I encountered the following errors when executing the test code proposed by the author of the library:

        alt text

        .pro file looks like this:

        alt text

        To solve the problem, I tried to rebuild the project.

        SOURCES +=

        qnx: target.path = /tmp/$${TARGET}/bin
        else: unix:!android: target.path = /opt/$${TARGET}/bin
        !isEmpty(target.path): INSTALLS += target

        win32:CONFIG(release, debug|release): LIBS += -L$$PWD/duckx/lib/ -lduckx
        else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/duckx/lib/ -lduckxd

          As suggested already by @jsulm , please don't list duckx headers in HEADERS variable.

          Can you paste the actual compiler output (Use Build>Rebuild, and paste the output of 'Comiple Output' pane?)

            After a short look at the duckx.hpp header file you will see that it lacks the proper import/export macros as described e.g. here. So you can either only build and link the library as static lib or add the correct macros.

                @Toruha said in undefined reference to duckx::Document::Document:

                c++11 console

                This doesn't tell me much, really!
                Did you use the Microsoft compiler (same as in Visual Studio)? Or did you use MinGW?

                    @Toruha You can't mix different compilers like in this case Microsoft compiler and MinGW. You have to build both, the library and your app, with same compiler.

                    But from your screen-shot above it rather looks like you're using Microsoft compiler...

                      Right, the _ITERATOR_DEBUG_LEVEL, RuntimeLibrary issues above rather show that you've done a Release build of duckx, but want to use it in a debug build of your app. This won't work; you need to compile both in the same configuration.

                        @jsulm I tried to rebuild under Microsoft compiler. What caused these new errors

                            @kkoehne Thanks. Everything works after changing the build type
