Problems with boost due to wrong version of g++?

I'm working on a program that worked on the original computer I used. I also got it to work on another computer, after I deleted the lib directory in home/myname/Desktop/MyProject/build/lib because it contained boost files that are outdated and caused a huge list of errors, possibly because of a conflict since I newly installed boost files in usr/lib and usr/include on this new computer. However, I'm working on another computer and now can't get this program to compile. If I now try to delete that lib folder, it just gets created again when I type ccmake .. and then the lib files the program uses are inserted there after I type make. However, the boost lib files are now not inserted in there

When I go to build and type make, I get a bunch of errors: http://ift.tt/1JnzZof

This is despite the fact that g++ --version says I have g++ 5.2 already installed and when I try to install build-essential it says build-essential is already the newest version. I think the previous computers I used had g++ versions of 4.8 or lower? Could that be why this program can't work on my new computer?
