Surface Matching module gives wrong result on archlinux

[lihk11]

System information (version)

• OpenCV => 4.1.2
• Operating System / Platform => Arch Linux/ 5.2.14
• Compiler => gcc

Detailed description

When I compile "ppf_load_match.cpp" along with the whole OpenCV project, the result just goes well. But when I try to use the same sample code in a standalone cmake project, it gives a wrong one, like the following output. It seems that every element equals to 0 ...

• Pose to Model Index 0: NumVotes = 48, Residual = 0.000000 [1.630416631276114e-322, 4.678743796305481e-310, 6.922983242403995e-310, 4.678608658560999e-310; 1.630416631276114e-322, 4.67860865987798e-310, 4.678603857321961e-310, 4.678608661343576e-310; 1.630416631276114e-322, 4.678608665164878e-310, 4.678603857321961e-310, 4.678608659876399e-310; 4.792436764660091e-322, 6.923014081302762e-310, 4.678603886829142e-310, 1.581010066691989e-322]

My CMakeLists.txt:

cmake_minimum_required(VERSION 2.8) project( test ) find_package( OpenCV REQUIRED ) include_directories( ${OpenCV_INCLUDE_DIRS} ) add_executable( test test.cpp ) target_link_libraries( test ${OpenCV_LIBS} )

The same configuration works well on Ubuntu 16.04.

find_package( OpenCV REQUIRED )

What package version is used? Is OpenCV_DIR specified properly? Easy way to check this via compiler options paths (make VERBOSE=1 or ninja -v) Or dump cv::getBuildInformation() from your .cpp file.

Thanks for your reply! I'm using 4.1.2, just cloned from master branch.

I tried make VERBOSE=1. Here are the outputs, I can't see anything wrong..., Could you check it for me?
