    It looks like you're not following my recommendations :-)
    Forget about the automatically created .pro file, change it by hand. Please compare the two lines I posted with what you have now...

      @Pablo-J.-Rogina I'm sorry but I did try the lines you suggested as I mentioned in my first reply to you. But it created 11 errors for each of the BL_ functions in my mainwindow.cpp.
      Maybe the error is now with the functions I used.
      I directly copied from the sample code on the Bitscope Library manual, these lines:
      BL_Intro(BL_ZERO); /* optional, default BL_ZERO /
      BL_Delay(BL_ZERO); /
      optional, default BL_ZERO /
      BL_Rate(MY_RATE); /
      optional, default BL_MAX_RATE /
      BL_Size(MY_SIZE); /
      optional, default BL_MAX_SIZE /
      BL_Select(BL_SELECT_CHANNEL,MY_CHANNEL); /
      choose the channel /
      BL_Trigger(BL_ZERO,BL_TRIG_RISE); /
      optional when untriggered /
      BL_Select(BL_SELECT_SOURCE,BL_SOURCE_POD); /
      use the POD input /
      BL_Range(BL_Count(BL_COUNT_RANGE)); /
      maximum range /
      BL_Offset(BL_ZERO); /
      optional, default 0 /
      BL_Enable(TRUE); /
      at least one channel must be initialised */

      Very much appreciate your support :)

      I'll add the full code just in case:
      #include "mainwindow.h"
      #include "ui_mainwindow.h"
      #include "limits.h"
      #include "bitlib.h"

      int x1=0, yl=0, x2=0, y2=0, x3=0, y3=0, x4=0, y4=0;
      #define MY_DEVICES 1 /* open one device only /
      #define MY_PROBE_FILE "" /
      default probe file if unspecified */

      #define MY_DEVICE 0
      #define MY_CHANNEL 0
      #define MY_MODE BL_MODE_FAST
      #define MY_RATE 1000000 /* capture sample rate /
      #define MY_SIZE 4 /
      number of samples to capture */

      MainWindow::MainWindow(QWidget parent) :
      QMainWindow(parent),
      ui(new Ui::MainWindow)
      {
      ui->setupUi(this);
      BL_Intro(BL_ZERO); /
      optional, default BL_ZERO /
      BL_Delay(BL_ZERO); /
      optional, default BL_ZERO /
      BL_Rate(MY_RATE); /
      optional, default BL_MAX_RATE /
      BL_Size(MY_SIZE); /
      optional, default BL_MAX_SIZE /
      BL_Select(BL_SELECT_CHANNEL,MY_CHANNEL); /
      choose the channel /
      BL_Trigger(BL_ZERO,BL_TRIG_RISE); /
      optional when untriggered /
      BL_Select(BL_SELECT_SOURCE,BL_SOURCE_POD); /
      use the POD input /
      BL_Range(BL_Count(BL_COUNT_RANGE)); /
      maximum range /
      BL_Offset(BL_ZERO); /
      optional, default 0 /
      BL_Enable(TRUE); /
      at least one channel must be initialised */
      }

      MainWindow::~MainWindow()
      {
      delete ui;
      }

      void MainWindow::on_btnCharge1_clicked()
      {
      x1 = ui->txtCharge1->text().toInt();
      }

      void MainWindow::on_btnCharge2_clicked()
      {
      x2 = ui->txtCharge2->text().toInt();
      }

      void MainWindow::on_btnCharge3_clicked()
      {
      x3 = ui->txtCharge3->text().toInt();
      }

      void MainWindow::on_btnCharge4_clicked()
      {
      x4 = ui->txtCharge4->text().toInt();
      }

      void MainWindow::on_btnCalibrate_clicked()
      {

      QVector<double> x(4),y(4);
      x[0]=x1;
      y[0]=yl;
      x[1]=x2;
      y[1]=y2;
      x[2]=x3;
      y[2]=y3;
      x[3]=x4;
      y[3]=y4;
      ui->Plot->addGraph();
      ui->Plot->graph(0)->setData(x, y);
      // give the axes some labels:
      ui->Plot->xAxis->setLabel("x");
      ui->Plot->yAxis->setLabel("y");
      // set axes ranges, so we see all data:
      ui->Plot->xAxis->setRange(0, 100);
      //ui->Plot->yAxis->setRange(0, 1);
      ui->Plot->replot();
      

      }

        Hi and welcome to devnet,

        Did you check that both Qt and BitScope are built for the same architecture ?

          @manuja I've just created a basic Qt GUI application, I hope you can grab code snippets from Bitbucket (sorry no time for a full Git repository).

          The application just displays a main window, nothing fancy, but by doing that most of the Bitscope functions you posted previously are called from QMainWindow constructor, so that proves Qt was able to build and run the application.

          As @SGaist mentioned please pay attention to what Bitscope version you're using (I mistakenly used x64 version initially, reinstalling i386 made the way with my environment: Win 7, Qt 4.7.4 and MinGW 32 bit)

            @Pablo-J.-Rogina Thank you very much!!!
            I'll try this. I actually tried the same library functions in a C++ console application on Codeblocks and they worked fine. I'll try with your code. Thanks again :-)

              Hello I have problems to use functions of bitlib.lib.
              I created a project without Qt, a c++ application, in qt-creator 4.9.2 (Community) version and build with the Qt 5.13.0 MinGW 64-bit and qmaxe.exe. It works for the function BL_Initialize() and every function with the return type void. But the others are not working and i get undefined reference to BL_Delay for example. Mabye someone had the same problem and can help me.

              Thanks in advance for a solution

                Hello I have problems to use functions of bitlib.lib.
                I created a project without Qt, a c++ application, in qt-creator 4.9.2 (Community) version and build with the Qt 5.13.0 MinGW 64-bit and qmaxe.exe. It works for the function BL_Initialize() and every function with the return type void. But the others are not working and i get undefined reference to BL_Delay for example. Mabye someone had the same problem and can help me.

                Thanks in advance for a solution

                Alex

                @alexfi Is there only one library file? Sometimes functionality is spread across several library files.

                  @alexfi said in Library doesn't open:

                  -BitLib

                  This is wrong

                    There are two files available. The 64bit version and the 32bit version, I tried both and installed them into the C: programm folder.
                    after I get the undefinded reference there error there was the collect2.exe error.

                      I tried -lBitLib before, but there was the error lBitlib not found. After I changed the to -BitLib it was found. I thought that was linux syntax. Mabe you can help me to get this run.
                      I installed the library in the C: folder after that I include this two lines in the pro file. i also added the header file in the project

                      INCLUDEPATH +=C:/BitScope64/Library
                      
                      LIBS += -LC:/BitScope64/Library -lBitLib
                      
                      

                      then i receive cannot find lBitLib

                      the structure of the library folder is following:

                      ->Library
                         ->Document
                         bitlib.def
                         BitLib.dll
                         bitlib.h

                        I tried -lBitLib before, but there was the error lBitlib not found. After I changed the to -BitLib it was found. I thought that was linux syntax. Mabe you can help me to get this run.
                        I installed the library in the C: folder after that I include this two lines in the pro file. i also added the header file in the project

                        INCLUDEPATH +=C:/BitScope64/Library
                        
                        LIBS += -LC:/BitScope64/Library -lBitLib
                        
                        

                        then i receive cannot find lBitLib

                        the structure of the library folder is following:

                        ->Library
                           ->Document
                           bitlib.def
                           BitLib.dll
                           bitlib.h
                           BitLib.lib
                           BitLib.pas
                        
                        -BitLib.dll
                        -BitScope.prb
                        -BitServe.prb

                          It's msvc, so according to the docs it must be

                          LIBS += C:/BitScope64/Library/BitLib.lib

                            @pablo-j-rogina

                            I am not sure how to include this correct in my pro. file do you have an example or some explanations for this?

                            g++ -o build/bin/myapp _mylib.so other_source_files
                            

                            Thank you for your help!!!

                            @Christian-Ehrlicher
                            I tried this also, but I get the undefined reference.

                            Thank you also for your help!!!

                            i also changed the library files from 64bit to 32bit because of that

                            //qmake: qmake.exe ConnectBitScope.pro -spec win32-g++ "CONFIG+=debug" "CONFIG+=qml_debug"

                                @alexfi said in Library doesn't open:

                                LIBS += -LC:/BitScope64/Library -lBitLib

                                I have done that several times and it used to work with MinGW and MSVC too. Can you show the linker command line from Compile Output?

                                Which MSVC version do you use?

                                The reason to prefer the -L/path/to/lib -llibname syntax is that Creator recognizes this and adds /path/to/lib to your Run Environment so your program finds the DLL automatically.

                                Qt has to stay free or it will die.

                                  @christian-ehrlicher I used that syntax before, but even MSVC can be feed with the Linux syntax (I guess qmake maps that), and that has advantages in Creator, see my last post.

                                    @Pablo-J-Rogina

                                    I saw the example but i think this is for librarys with the ending .so I am no sure how to use this in my case

                                      @alexfi said in Library doesn't open:

                                      In that case, something is really weird set up - no wonder that it doesn't work.

                                      Your compile output clearly shows the MinGW linker running.

                                      Qt has to stay free or it will die.

                                        I think this is the Compile Output you need:

                                        
                                        g++ -Wl,-subsystem,console -mthreads -o debug\ConnectBitScope.exe debug/main.o  -LC:\BitScope32\Library\BitLib.lib   
                                        debug/main.o: In function `main':

                                        I saw the example but i think this is for librarys with the ending .so I am no sure how to use this in my case

                                        you may want to try with .lib in your case

                                          I tried it like this :

                                          g++ -o$$PWD/ $$PWD/BitLib.lib
                                          
                                          but i get the "extra characters after test expression" error
