I heard STL is a good tool, so I installed STL on my compiler. The problem is, when I use deque, everything is fine. But when I use destack, it gives me this error:

[Error] destack: No such file or directory compilation terminated.

I'm using the last version of MinGW GCC installed with the MinGW GCC Package Manager, with compile flags -std=c++14 -O2. My friend also have this problem. So please help.
