This is bugging the hell out of me. This should be basic C++ stuff, like I figured out over a year ago. I've used strings so many times.

Why don't they work here?

Basically I'm creating a "tile" class, and one of its variables is supposed to be a string. This string will be something like "forest.png" so I can have tiles for basic terrain types.

Should be EASY.

Like this:



Yeah, so I'm still working on it. But even this basic class won't work. It behaves like the string class doesn't exist:

error C2065: 'string' : undeclared identifier

What's going on? How can I hold the filename if I can't use strings?

You didn't declare "using namespace std;".

Alternatively, add 'using std::string' to your code

I never use usings, because it can cause clashes when using multiple libraries.

Never had that before. Besides, if you ever need to get it back to char* form, you just gotta do (char*)str.c_str().

That's why you only use 'using std::string' rather than 'using namespace std'. That way only the string class is imported

I'm getting confused because I still have a problem and it's a different one than I remember.

When I stick:

#include <string>

anywhere in my code, I get compiler errors. Simply telling it to add that library makes it unable to compile, whether or not I try to actually use a string.

Here is the compiler error (Visual Studio 2008 Express):

Click Project->Project Properties (bottom one)->Configuration Properties->C/C++->Code Generation, and set the Runtime Library to /MT.

That should fix it.

Thank you! That worked.

I assume that's documented somewhere and I just missed it? Do I have to set it for each project individually?

You have to set it for any project that uses std or, probably, any third party library that has a debug version. DGDK doesn't have a debug version so it causes some clashes. The alternative is to compile in Release mode but that means you can't debug very well.
