You may want to enable tests in CMake and then run “ctest” in your build tree to verify that the tests pass. There are some known issues with the last official release of VXL (1.17), but the master branch should work. You said VXL 1.18, I’m not sure that that exists.</div><div class="" style="line-height: 21px;"><br class=""></div><div class="" style="line-height: 21px;">The correct way to call maptk_track_features (or any MAP-Tk tool) is with the “-c” to specify the config file. In your last example without the “-c" the config check failures are because the tool is not reading the config file and just using the default config values.</div><div class="" style="line-height: 21px;"><br class=""></div><div class="" style="line-height: 21px;">In the case where you are correctly using “-c”, the exception you are getting indicates “Path does not exist”. This is most likely related to loading image files. Your config file should have “image_list_file” set to a path to a text file in which each line in the file is a path to one image to load (i.e. each frame of video). What is the contents of your image list file? Is it empty or does it have a blank line?</div><div class="" style="line-height: 21px;"><br class=""></div><div class="" style="line-height: 21px;">—Matt</div><div class="" style="line-height: 21px;"><br class=""></div><div class="" style="line-height: 21px;"><br class=""></div><div class="" style="line-height: 21px;"><br class=""><div class=""><blockquote type="cite" class=""><div class="">On Jul 1, 2015, at 11:30 PM, Stedraw <<a href="mailto:527063960@qq.com" class="">527063960@qq.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">Hello, thank you for reading (^_^)</div><div class="">I have installed :</div><div class="">Boost 1.58 ,</div><div class="">Eigen 3.25 ,</div><div class="">opencv 2.4.11 (the latest version 3.0 can't work with maptk, because it doesn't have Algorithm::_create() ), </div><div class="">proj 4.91 , </div><div class="">VXL 1.18 .</div><div class="">Then I built maptk sucessfully.</div><div class=""><br class=""></div><div class="">But when I ran <span class="" style="color: rgb(0, 0, 128);">maptk_track_features </span>, I can't get the output</div><div class=""><br class=""></div><div class=""><div class=""><font color="#000080" class="">stedraw@stedraw-PC:~/maptk/maptk/bin$ ./maptk_track_features -c track_feature.conf -o track_feature.conf</font></div><div class=""><font color="#000080" class="">File parsed!
