Examples dont work #254

Good day.

I build your project and examples with opencv 4.3.0, but it doesn't work

Steps: 1) build opencv 2) git clone https://github.com/ShiqiYu/libfacedetection 3) cd libfacedetection 4) mkdir build && cd build 5) cmake -DDEMO=ON -DOpenCV_DIR=/home/i123/install/lib/cmake/opencv4 .. && make 6) ./detect-camera-demo 0

And as result I got this :"Illegal instruction (core dumped)"

Might your library work under Ubuntu?

Allius27 commented 4 years ago

Or is that incompatible with latest opencv?

ShiqiYu commented 4 years ago

maybe you enabled AVX2 or AVX512 that your CPU doesn't support.

Allius27 commented 4 years ago

True, examples work with turned off AVX2 and AVX512 options(intel core i7)

Thank you for advice

ShiqiYu commented 4 years ago

You can enable AVX2 and disable AVX512 to gain better speed

I tryed build project with different options, and for it works only with turned off options

ShiqiYu commented 4 years ago

It's strange. i7 CPU should support AVX2.
