Hello everyone, The OpenCV version I'm currently using is OpenCV 3.4 .

I'm trying to compile a sample program from github. But, I'm receiving the following errors:

/tmp/cctdl0lP.o: In function `createBGSubtractorByName(cv::String const&)':
bgfg.cpp:(.text+0xfd): undefined reference to `cv::bgsegm::createBackgroundSubtractorGMG(int, double)'
bgfg.cpp:(.text+0x190): undefined reference to `cv::bgsegm::createBackgroundSubtractorCNT(int, bool, int, bool)'
bgfg.cpp:(.text+0x2b8): undefined reference to `cv::bgsegm::createBackgroundSubtractorMOG(int, int, double, double)'
collect2: error: ld returned 1 exit status

I found the similar problem referred here. And hence I included the following:

#ifdef _DEBUG                   
#pragma comment(lib, "opencv_bgsegm340d.lib") 
#else
#pragma comment(lib, "opencv_bgsegm340.lib")               
#endif

Yet, the problem doesn't seem to be solved. Kindly, help.

Thanks in advance.

Thanks, @StevenPuttemans.That helped!

@LBerger well, No. It is a library to include few background subtraction modules such as MOG and GMG. Unfortunately, whe

@LBerger the platform I'm working on is g++.

I just found out that the OpenCV version that I recently installed(i.e. version 3.4.0) doesn't have opencv_bgsegm340.lib
