@JonB Oh yeah sorry.. I wasn't reading the right. It was opening in a VS text editor. I tried running it with notepad and it worked. I guess VS has something where they keep the file open, so i couldn't edit it and then update the display.

After so many attempts without luck, the first attempt I try after writing this reply is a dfferent error :) So the boost is no longer my problem. For other people that my face the same problem as me, in the includepath just add: '$(BOOST_ROOT)'

Just did mark it as solved. This might be because you have signed up lately. Not sure what the restrictions are, but it is meant for spam prevention. Otherwise at your top post respectively any other post you should see a gear wheel at the right. Click on this and on the left button showing up. In general it is self-explanatory and I am sure you will find it next time.
