I’m trying to compile the files exactly as given but I get the following errors:

In particular, “to_string is not a member of std” is concerning me. I googled it and it says that this is a problem with mingw but I’m using the most recent version of code::blocks which should therefore have the most recent mingw. What could I do to make this work?

dont be just copying and pasting demos and tutorials from the internet,
read about SDL, c++ and its libraries.
and if you are going to use a tutorial, a tip: write everyline of code of
the tutorial on your own. that way at least you have some kind of sense of
what the program is doing.

also be sure you have

#include

The tutorial isn’t explained. It is just source. Normally I can figure out what works and what doesn’t this way if I know it will compile.

also codeblocks uses a version of mingw really outdated and with a lot of
bugs, check out http://mingw-w64.sourceforge.net/, is better.
somebody explained it here: stoi and c++ 11 - C++ Forum

std::to_string() also happens to be a C++11 feature. You have to turn on
C++11 support explicitly for your compiler. Use the compiler flag
-std=c++11 or -std=gnu++11.
