Opencv undefined reference to symbol '_ZN3tbb18task_group_contextD1Ev' when running with tbb [duplicate]

I am just trying to process multiple images using tbb in OpenCV as found in this question.

The following is my sample code.

#include <opencv2/opencv.hpp> #include "tbb/tbb.h" using namespace tbb; using namespace cv; using namespace std; void processBinary(Mat image) { //image processing Mat gray; cvtColor(image, gray, CV_BGR2GRAY); } int main( ) { Mat m1, m2, m3, m4; m1 = imread("test1.jpg", IMREAD_COLOR); // Read the file m2 = imread("test2.jpg", IMREAD_COLOR); // Read the file m3 = imread("test3.jpg", IMREAD_COLOR); // Read the file m4 = imread("test4.jpg", IMREAD_COLOR); // Read the file std::vector<cv::Mat> input = { m1, m2, m3, m4 }; tbb::parallel_for(size_t(0), input.size(), size_t(1), [=](size_t i) { processBinary(input[i]); }); return 0; } 

I ran the file using the command - g++ test1.cpp -a app `pkg-config --cflags --libs opencv

I got the following errors:

/usr/bin/ld: /tmp/cc79ceOq.o: undefined reference to symbol '_ZN3tbb18task_group_contextD1Ev' //usr/lib/x86_64-linux-gnu/libtbb.so.2: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status 

Any help is appreciated !!
