ambiguous Symbol

Hi,

i Have the following code:

using namespace std;
char str[2000];
string file = "foo.txt";
char* cwd = getcwd(NULL, 0);
string path = cwd;
free(cwd);
(path += "/") += file;
fstream file_op(path.c_str(), ios::in);
file_op.getline(str,1999);
file_op.close();

problem is i am getting an error during compile:

error C2872: 'fstream' : ambiguous symbol


i searched and i found that it might have something to do with headers. These are the headers i used:


#include <windows.h>
#include <fstream.h>
#include <direct.h>
#include <string>

(note that the above is only a portion of the full code)


anyone know what is causing the error? thanks

try include
#include <fstream>
instead of
#include <fstream.h>

Do not mix up non-standard headers with standard headers. Always use the standard headers (the headers with no .h).

Corrections:

Code:

---

#include <fstream>  // no .h

hi,

that worked.. but now i am getting different errors during linking:


LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/main.exe : fatal error LNK1120: 1 unresolved externals

would you please write the whole code/program

Are you sure that you have a main() in your program?

I included tchar.h and it worked fine.. i wonder why ..
