it failed for me with the following error:

'O0' is an unknown mex argument

Do you know how to fix this?

Thank you

To fix 'nvcc fatal : '-DNDEBUG': expected a number' ,
I changed 'O' to 'O0' from line 340:
flags.base{end+1} = '-O0' ;

But I still get an error like :

Error using mex
Unknown MEX argument '-O0'.

Error in vl_compilenn>mex_compile (line 584)
mex(args{:}) ;

Please give me any advice.

You just need to comment the line 340 (flags.base{end+1} = '-O' ).

You just need to comment the line 340 (flags.base{end+1} = '-O' ).

Thank you for your answer, I also meet this question. Is there any defect to comment this line340? Thank you.
