i tried to compile this but it said that there is no such file reagarding <sstream>Code:#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
int main()
{
stringstream ss;
string data;
ifstream in;
in.open("stores.ddf");
ss << afile.rdbuf();
}
what have i done?
cheers.
Well, what compiler? You are also not using any std:: anywhere and there is no afile stream object anywhere.
still a noob, i'm using DEV-c++.Quote:

Right-Click the project name on the left-hand side list. Choose Project Options->Files Tab. Select the cpp file and make sure "Compile file as C++" is checked. If you still have the same problem, or it is already checked, go to Tools Menu->Compiler Options->Directories Tab->C++ Includes Tab and tell us what paths it has listed.
Also, when creating new projects make sure you specify them as C++ on the first dialog screen.
thanks, it's obveously the compiler it's self because i put the code into another compiler and it worked, <fstream> didn't return an error so it woudn't be in C right?Quote:

I assummed 4.992 was the final version of dev. Bloodshed abandoned any more versionsQuote:

its the same thingQuote:

Compiling from another place will not solve the problem nor will it tell you what is wrong. Do the tests I suggested you previously.

i don't understand what you mean you seem to be very knowledgable when it comes to c++ programming so you should understand the logics in the elimination process,
if <sstream> isn't working in one compiler but does in another it must be the compiler, as for the reason behind why the compiler doesn't accept the header <sstream> ........ knows.
is there anything wronge with my methods?
Thats down to either the compiler vendors, or the header librarys contained in the include directorys of that particular compiler. No compiler to my knowledge is fully C++ compliant. Many of the MS ones have almost all avalaible header files. DevC++ has the vast majority of them.
One option to check if your particular compiler has sstream is to look in the folder containing the pre-made header files. If sstream is indeed included, then it "should" reconsize it as a valid header. Since C++ has backward compatability with C, if you create a C++ project or even a C++ source file, any C headers will be reconized.
If on the other hand the include folder does not contain sstream, then you know it is down the compiler vendors choosing not to include it as a header library. Since Dev is quite old, getting patches and updates for it is impossible. Although with a MS IDE you get the ability to download platform SDK's and toolkits. If all else fails, this may be a logical solutuon
What compiler would you recommend? i have been using DEV- since i started but it is starting to limit what i can do !Quote:

The original code posted is wrong because it doesn't specify the std namespace. Otherwise it should work.
If it doesn't work and you are using the latest version of Dev-C++, it is not the compiler's problem, it is an error with how you are using it. Other than the need to add the std namespace, there's nothing obvious that you are doing wrong that we can see.
Just my two cents, it's true that without specifying the std namespace, it will become an error. However, the error message will be different with what wart101 experienced. There's one other possibility. Maybe the installation of the compiler was corrupt or something. Try reinstalling the compiler and see how it compiles again. I have a similar issue before with a corrupt Visual C++ 6. And when I reinstalled the Visual Studio, it worked fine.
I echo that problem g4j31a5. When I first installed that same software at college and ran my larger programs, I kept getting an error up saying the software had encountered a problem. Even 2005 version has done it a once. It a little glitch we have to put up with once in a while. Best idea is to make sure you save the files regually. Then, if it does crash, you will not lose much of what you just did.
