  Well, my code is looking like that:

  /**********variables**********/ QwtPlotMarker markers_array[1024]; QwtSymbol sym; /*****************************/ /*part where i create symbol for markers*/ sym.setSize(QSize (1,1)); sym.setColor(Qt::black); sym.setStyle(QwtSymbol::Ellipse); /*part where i plot markers*/ for (int counter = 0; counter < size; counter++)/ { markers_array[counter+filler_count].setSymbol(&sym); markers_array[counter+filler_count].setValue(QPointF(I[counter], Q[counter])); markers_array[counter+filler_count].attach(ui.vector_plot); } /*part of the code, where application is closing*/ app::~app() { for (int i = 0; i < 1024; i++) { markers_array[i].detach(); } ui.vector_plot->detachItems(QwtPlotItem::Rtti_PlotMarker, false); ui.vector_plot->replot(); sym.~QwtSymbol(); }

  Problem appears, when i'm trying to close application.

  @Hyo.

  This is not a Qt problem.

  The only relation to Qt is that you happen to use the MinGW compiler installed with Qt libraries. However, MinGW is not part of Qt either. It is from a separate open source project.

  The problem is obviously that a routine closesocket is referenced (even the line is given in your post) but not found as a compiled module. As with any source you need to find out where it belongs to and why it is not compiled or part of a library you are using.

  Hi,

  I'd recommend contacting this library author(s). This module isn't even part of PyQt.

  When I am building my project then it shows the inbuilt header files of Qt as "No such file or directory exist"
  Do I need to set path with every include statement in my project?

  @shashi-prasad said in installation of QT creator 5.6.0 with gstreamer on Windows 10:

  gstreamer-1.0-x86_64-1.12.1

  This is not a devel package so .lib files are not likely to be included. I would suggest using gstreamer-1.0-devel-x86_64-1.12.1.msi instead.

  Did you install Qt from the online/offline installer or are you using the Qt coming with your distribution ?

  In the second case, did you instal the matching debug package from the package manager ?

  @SGaist
  I believe I found the issue:

  Galil's installer placed the *.dll in a different path than the *.lib files:

  ..\gclib\dll\x86

  versus

  ..\gclib\lib\dynamic\x86

  When I copied the *.dll files to the same folder as the *.lib files, the problem went away.

  ..... the problem is about WITH_QT flag in cmake ..... I flak it on cmake-gui but I read that command enable support to qt4 only and make problem onto ubuntu 16.04 and major than QT5.2 .... opencv run in stand alone mode but inside qt project make these type of error .... so clean all my pc from opencv and re-install (i test opencv3.2) without WITH_QT flag .... all works like a charm.

  @pdsc_dy said in building LLVM with Qt:

  I am using vc++ with cmake for win32 project. I am trying to develop a simple language that allows a user to customize certain input, which will then be translated to IR and compiled with llvm.

  It sounds like you want to link to LLVM. You don't need to build LLVM, and you don't need to build Qt.

  Just use LLVM as an external library. See http://doc.qt.io/qtcreator/creator-project-cmake.html#adding-external-libraries-to-cmake-projects as a starting point.

  @Faisal_Ali

  In Qt creator you have a project file with the extension .pro

  Check the entries in this file. There typically some entries like

  SOURCES += main.cpp\ MainWindow.cpp \ MyRadio.cpp \ MyRadioLine.cpp \ MyLine.cpp HEADERS += MainWindow.h \ MyRadio.h \ MyRadioLine.h \ MyLine.h FORMS += MainWindow.ui

  Under SOURCES all files for compilation have to be listed.
  Under HEADERS all include files are listed.

  Most likely the source file with your source code of structured_light is missing.

  If so, the source file is not compiled and cannot be linked to your application.

  Sorry for zombieing this one.
  What that library does is loading all the data from the existing file and re-build it from scratch when you click save this means that any feature that existed in the original file but it's unsupported by the library will be removed on save just because the library doesn't even know they exist
