thanks for guiding me @berak.

Hi. I've taken interest on OpenCV and installed it on my machine with pacman package manager as I'm running with Arch Linux directly from the repository including the samples which is in a separate package. I tried compiling the source found in the /usr/share/opencv/samples directory with cmake . and then make. It compiles some of the examples, but it stops at 3% and shows the following error:

/usr/bin/ld: CMakeFiles/example_contours.dir/contours.c.o: undefined reference to symbol 'lrint@@GLIBC_2.1'
/usr/lib/libm.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
c/CMakeFiles/example_contours.dir/build.make:109: recipe for target 'c/c-example-contours' failed
make[2]: *** [c/c-example-contours] Error 1
CMakeFiles/Makefile2:236: recipe for target 'c/CMakeFiles/example_contours.dir/all' failed
make[1]: *** [c/CMakeFiles/example_contours.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2

I've already tried searching the web, but I couldn't find any answers on how to deal with this error. Can anyone please point me into the right direction, as all I wanted was to run the samples.
