Hey Derzu, We wanted to run the code for webcam, so I comment out this line in Makefile。 #CFLAGS += -DDEPTH

It was compiled successfully. But when I tried to run BodySkeletonTracker , I got the following error:

james@james-virtual-machine:~/BodySkeletonTracker/Bin/x64-Release$ ./BodySkeletonTracker 
main::Compilado SEM Depth
Compilado SEM Depth
select timeout
select timeout
OpenCV Error: Assertion failed (total() == 0 || data != __null) in Mat, file /home/james/opencv/modules/core/include/opencv2/core/mat.inl.hpp, line 500

  what():  /home/james/opencv/modules/core/include/opencv2/core/mat.inl.hpp:500: error: (-215) total() == 0 || data != __null in function Mat

Aborted (core dumped)

Could you please help me understand this?

Regards, james

Hi Linzheming,

Did you tried to compile with the original Makefile? If so, use the file Makefile.noDepth.

You can simply replace the files doing:

mv Makefile.noDepth Makefile

Please try that and give me a feedback.

Best regards,

Derzu.
