Set up OpenCV in Visual Studio 2017

Download Visual Studio 2017: https://visualstudio.microsoft.com/downloads/

Download Cmake: https://cmake.org/download/

References:

https://github.com/opencv/opencv opencv-master

https://github.com/opencv/opencv_contrib contrib libraries

Download OpenCV from github site

then extract into a folder name Opencv-master:

then, using CMake to  extract Opencv-master into a folder name OpenCVGithub:

Then Configure => choose some other value like OpenGL, OpenMP or un-tick in BUILD_JAVA

ð  Generate

Run OpenCV.sln from C:\Dev\Libraries\OpenCVGithub

From Solution Explorer part => Run ALL_BUILD for Debug X64 and for RELEASE X64 (long time)

Then Run INSTALL for Debug X64 and for RELEASE X64 (faster)

Going to: View => Property Manager

Type env to find Environment Variables from System Properties

Choose New – Var name: OPENCV_DIR with C:\Dev\Libraries\OpenCVGithub\install\x64\vc15

in Path: create two new paths: %OPENCV_DIR%\bin ; %OPENCV_DIR%\lib

Now open project and set up environment and library for the project:

C/C++ - General: $(OPENCV_DIR)\..\..\include       (% mean module, \.. turn back 1 directory)

Explain for \..\..

OPENCV_DIR: C:\Dev\Libraries\OpenCVGithub\install\x64\vc15

Include: C:\Dev\Libraries\OpenCVGithub\install\include

How to Setting Qt GUI using C++ with Visual studio 2017

Payialee VARTOU (Pary)

Jul 19, 2018

(including some example)

“C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do it blows your whole leg off” (Bjarne Stroustrup)

Firstly i wanna to explain about Qt “What is Qt ?” why I use Qt for create GUI? I know that is the first question that everyone want to know :) Okay let’s go!

#What is Qt?

(You can find more information about Qt from this URL: https://www.qt.io/)

Qt is much more than just a cross-platform SDK-it’s a technology strategy that lets you quickly and cost-effectively design, develop, deploy, and maintain software while delivering a seamless user experience across all devices. Easily create connected devices, UIs and applications with native C++ performance, Write your source code once, build and watch it run on any operating system and hardware. It’s truly cross-platform, Embrace the complete freedom to design tomorrow’s UIs. Use drag-and-drop tools, declarative QML or imperative C++ — the choice is yours, You can design your UI, write your code and much more in one cross-platform IDE. (https://www.qt.io/)

#Step 1: If you already install Visual Studio than just go to this URL https://www.qt.io/download

Download the open source version of Qt(Latest version is 5.10.1) that is suitable for your operating system. this will be automatically detected.

#Step 2: Start the installation. When asked for username, you have the option to skip that step and make sure you install the prebuilt components for the compiler you are using (MSVC2017/ MSVC2015), sources, charts and data visualization component and debugger support like this:

Now you have scroll down and select Tools, Qt Source, Qt chart and also Qt Data Visualization.

#Step 3 : Download and install the Qt Visual Studio Tools from : https://marketplace.visualstudio.com/items?itemName=TheQtCompany.QtVisualStudioTools-19123

#Step 4:

Open Visual studio, if the Qt VS Tools were correctly installed, you should find a new menu item “Qt VS Tools”.

#Step 5:

Add the path towards the components for the compiler: Qt VS Tools -> Qt Options-> Add button, Use the folder where you installed Qt

#Step 6:

Done! Restart Visual Studio and than let’s see how to create a new Qt project.

Creating A new Qt Project With VS STUDIO 2017

1. From the VS menu, select “File” -> “New” -> “Project”.
2. In the left-hand column of the “New Project” window, under “Visual C++” select “Qt”. In the middle column, select “Qt GUI Application”. Add a name and a location and then press “OK”.

You can save your application in any folders you want (Location)

3. In the following dialogs, keep the default settings (Next -> Next -> Finish).

4. In the “Source Files”, a file “main.cpp” should already be created (other .cpp, .h and .ui files will also be created).

5. Run the application. You should see an empty window:

Now! It’s Done for create a Qt Project. :) See you Next Blog! (How to build GUI Using C++ with Qt Platform)
