Problems with fstream library.

[Netaro]

Hello!
Well, i tried to use the fstream library along with the irrlicht to try making some save game function. But, i noticed that there are some problems with the fstream. I included fstream, then i tried to make...

Code: Select all

ofstream Plik;
Plik.open("test.txt");
Plik << "test" << std::endl;
Plik.close();

Same problems with fstream & ifstream. Errors are->

Code: Select all

19 C:\Dev-Cpp\irr\main.cpp `ofstream' undeclared (first use this function) 
19 C:\Dev-Cpp\irr\main.cpp expected `;' before "Plik" 
23 C:\Dev-Cpp\irr\main.cpp `Plik' undeclared (first use this function) 

So, is there any solution to this problem?
Using Dev-cpp 4.9.9.2.

All classes in the iostreams library are in the std namespace. The easy fix would be to put a using namespace std; at the top of the file. Another solution would be to explicitly say which namespace the classes are in, like this...

Code: Select all

std::ofstream Plik;
//...

it's in the std namespace, you need to use

Code: Select all

std::ofstream Plik;

by the way, I'd advise against using dev-cpp, as it's been out of development for over a year. If you're an open source fanatic, code::blocks nightly builds are much more up to date.
Myself I prefer Microsoft's Visual C++ 2005 Express (free version, unlike some people here I have no moral objections to using Microsoft apps ), as the debugger is the best I've ever seen and very easy to use, it can debug inside Irrlicht.dll.

edit: damn! too slow!

it is matter of personal preference. I use DevC++ since I started to code in C++ and like it a lott.

bitplane >> from where do you know that its out of development for over one year? Not that I play close attention to it but last beta version (4.9.9.2) is not more than year old ...at last I think... I am going to have a look at their web page probably...

...you right it is from 5. November 2005

the sole reason I use Visual C++:


I used Dev-cpp for a long time, the profiler is good but debugging sucks. you can't debug inside DLLs (or at least I never worked out how to), it has a habbit of skipping over breakpoints, and it hangs randomly. Debugging with printfs is painstakingly slow.

I've not got the hang of codeblocks yet so I can't really comment on it. I will switch if/when it can offer me something like what you see above.
