Ubuntu build fails with memcpy not declared in string.h

Trying to build OpenCV on Ubuntu 16.04, make fails with an error compiling cuda file:

Thanks for reformatting.
I tried a fresh build using the following script :
https://github.com/milq/scripts-ubunt...
and got the same error.

i know, you might be tired doing this, but can you try to disable anything cuda related for a try ? (also, clean up your build folder)
(this would at least narrow down the problem)
Disable Cuda? hehehe... you know what I had to go thorugh last weekend to get the Nvidia card working at all? I ain't touching that... :)
hehe, i see. i can give out free hugs, but unfortunately i can't help here
would above comment be an answer ? is it solved now ?
(i'd just propell it to one, then (no need to wait for another 24 hrs)
Yes, the build just completed. I think the github page seemed to indicate that a bug was logged on this but apparently it has not been fixed. If you wish please move the answer over the the answer box.
sure ! will do !
