invalid suffix on literal; C++11 requires a space between literal and identifier

[kbitr]

Hey, I get the following Error on several machines. On another, it worked, but I can not see the difference.

Hi, what compiler version do you use for each case: when error occured, and when it worked well?

[kbitr]

Hey, apparently the above error message was created on a Mac (gcc 7, llvm 5). I wasn't able to reproduce the same error on the Linux machine of my colleague since I installed the build-essentials and others yesterday. On another machine, (Ubuntu 16.4, gcc-5, libopencv-dev 2.4.9.1) it compiled. I'm sorry for not being able to provide more!

Now with gcc-7, libopencv-dev 3.1.0, Lubuntu 17.10, Issue20 appears. But apparently, it is not fixed. I changed all lines to "waitKey" and it worked.

I hope it helps, I added the space that the error said C++11 required and the first part achieved the [100%] (as you can see in the code below). I basically put a space after each "" found as errors in main.cpp.

Now the error is:
