Compiling BGSLibrary with OpenCV 2.4.x and Visual Studio 2013 from CMAKE

Dependencies

• OpenCV 2.4.x
• GIT (tested with git version 2.7.2.windows.1).
• CMAKE for Windows (tested with cmake version 3.1.1).
• Microsoft Visual Studio (tested with VS2013).

Step-by-step Instructions

Please follow the instructions below:

1. Go to Windows console.

2. Clone BGSLibrary git repository:

git clone --recursive https://github.com/andrewssobral/bgslibrary.git

3. Go to bgslibrary/build folder.

4. Set your OpenCV PATH:

setlocal
set OpenCV_DIR=C:\OpenCV2.4.10\build

5. Launch CMAKE:

(For Windows x86 32bits) cmake -DOpenCV_DIR=%OpenCV_DIR% -G "Visual Studio 12" ..
(For Windows x64 64bits) cmake -DOpenCV_DIR=%OpenCV_DIR% -G "Visual Studio 12 Win64" ..

Now, you will see something like (for win64):

-- The C compiler identification is MSVC 18.0.40629.0
-- The CXX compiler identification is MSVC 18.0.40629.0
-- Check for working C compiler using: Visual Studio 12 2013 Win64
-- Check for working C compiler using: Visual Studio 12 2013 Win64 -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler using: Visual Studio 12 2013 Win64
-- Check for working CXX compiler using: Visual Studio 12 2013 Win64 -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Detecting CXX compile features
-- Detecting CXX compile features - done
-- OpenCV ARCH: x64
-- OpenCV RUNTIME: vc12
-- OpenCV STATIC: OFF
-- Found OpenCV 2.4.10 in C:/OpenCV2.4.10/build/x64/vc12/lib
-- You might need to add C:\OpenCV2.4.10\build\x64\vc12\bin to your PATH to be able to run your applications.
-- Configuring done
-- Generating done
-- Build files have been written to: C:/bgslibrary/build

6. Include OpenCV binaries in the system path:

(For Windows x86 32bits) set PATH=%PATH%;%OpenCV_DIR%\x86\vc12\bin
(For Windows x64 64bits) set PATH=%PATH%;%OpenCV_DIR%\x64\vc12\bin

7. Open the bgs.sln file in your Visual Studio and switch to 'RELEASE' mode

7.1) Note: if the version of your Visual Studio is superior than 2013, you need to 'CANCEL' the project wizard update. However, you can go backward to step (5) and change the Visual Studio version, e.g.: -G "Visual Studio XX", where XX is your Visual Studio version.

8. Click on 'ALL_BUILD' project and build!

9. If everything goes well, you can run bgslibrary in the Windows console as follows:

9.1) Running BGSLibrary with a webcamera:

C:\bgslibrary> build\bgslibrary.exe --use_cam --camera=0

9.2) Running demo code:

C:\bgslibrary> build\bgs_demo.exe dataset/video.avi

9.3) Running demo2 code:

C:\bgslibrary> build\bgs_demo2.exe

Additional information:

• Note that bgslibrary requires a 'config' folder in the working directory.
