    Hi,

    I have resolved all string related error. Now my project is showing this :-1: error: LNK1104: cannot open file 'freeimage.lib' . If i could find the Visual Studio equivalent or Project property in QT, that would be very helpful to very file the linker paths.

      @bhim
      you mean to link the LIB file to the project ?
      http://doc.qt.io/qt-5/third-party-libraries.html
      http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html

      Basically you need a
      LIBS += -L"3rdparty/CatWhisperer/lib" -lCatWhisperer
      (with correct names of course)

          Hi
          seems you need to link to
          Shell32.lib also
          https://msdn.microsoft.com/en-us/library/windows/desktop/bb762204(v=vs.85).aspx

            Thanks. I m able to build and run it now. But not able to find the output file, a .ds file anywhere? Can you please help me find where project is generating this file.

                    ds is Twain data source, OR Twain Driver. See below from my pro file, based on this it should have generated

                    TWAIN datasources end with a .ds instead of .so

                    QMAKE_POST_LINK = cp
                    $(TARGET)
                    $${PROJECT_FILE_NAME}.ds
                    ds.path = /usr/local/lib/twain/FreeImage
                    ds.files = $${PROJECT_FILE_NAME}.ds

                      Ok but a SO file is a DLL.
                      so being on windows, i wonder if the DS is just a DLL.

                      Is that to load into the sample project ?

                        I change the DLL extension to ds and replaced with original DS file. It dd not work, it was not even detected. I think if somehow i could emit a .ds file , it will work. Below is the project property of visual studio project which generated original ds file

                          Sorry i have no idea what / how a ds file should be produced.
                          Site says
                          copy TWAINDS_Sample[32|64].ds to /Windows/twain_[32|64]/sample2
                          so it looks like a DLL. but sadly i cant find out more.

                            Coding wise everything looks fine, I am trying to debug ds file using a sample connection application. But connection application itself is giving below error. Can you please help.
