i get error while running the sample code provided in opencv-contrib github.

0xC0000005: Access violation reading location 0x00000000.

after my research i found out its def-referencing a pointer.

the exact location of error is line93 in the code stated in link above.

how can i avoid this error??

Comments

the error is certainly not in the code (it runs fine elsewhere, and for other folks)

any chance you're mixing release and debug libs in your project ?
did you build the opencv libs from exactly the same opencv and opencv_contrib version ?
don't link to opencv_world !

Thanks so much for your response.

my project does not build for release version even if link libraries properly it gives link error.
i downloaded the latest version of opencv and opencv- contrib from github.
can you recommend the version you have used for your codes.

i used instructions from this website for my building with cmake.

clean your build folder, and try to re-run cmake (with path to opencv_contrib/modules added)

if you get build errors, please show us.

(i've been trying with 3.4 / master yesterday, but it worked fine with all previous versions before)

okay i will do that. i will get opencv3.4 and opencv_contrib and start everything again. i would like to mention i am using windows.
