The problem is "expected primary-expression before '{' token"

in this part of the code:

Are you compiling your code as C++11/C++14? Try passing -std=c++14 or -std=c++11 as a command line argument to your compiler.

Man I am in trouble with those compilers, editors. I recently started to use code::blocks for this c++14 issue and now same errors keep coming up.

||unrecognized command line option "-std=c++14"|

it says. I am really pissed off right now.
LB (13399)
I believe that you can tell Code Blocks to use a different MinGW installation - just download nuwen MinGW and point it to that:
http://nuwen.net/mingw.html
istemihan (45)
I have tried that :) installed MinGW and waked through the instructions. Do I have to do anything after those instructions?
LB (13399)
Change your Code Blocks settings and point it to C:/MinGW or whatever it needs to understand that that's where you want it to find the compiler and libraries.
