Revision history [back]

I resolved this issue, after removing this -lgflags_nothreads_static from modules/sfm/CMakeFiles/opencv_sfm.dir/link.txt (as there was no lib file for gflags_nothreads_static from gflags) file OpenCV sfm module compiled successfully and executable for example_sfm_trajectory_reconstruction.cpp was generated. Thank you for yoru helps @berak and @LBerger.
