I am trying to build the master (a98fe8b814ed4ad9007524c62763c5e56dd2c368) and run test on Ubuntu 18.04 but test are failing:

$ git clone https://github.com/erikzenker/inotify-cpp.git
$ mkdir build_release && cd build_release

@elvisdukaj thank you for the bug report. Sadly, the test does not fail on my arch linux system. I will setup a ubuntu vm and try to reproduce the issue.

[erikzenker]

Okay, I was able to reproduce it on ubuntu 18.04. I will start to work on a fix.

[erikzenker]

I merged #64 to master. Can you check if it works on your system?

[elvisdukaj]

I updated it and now it's working properly! Thank you!
