String problem when compiling with gcc3.0.2 in an Alpha with Tru64

[Jorge Andreu García <jandreu at gmv dot es>]

Hello.

 

Trying to compile a short "Hello World!" program I have had several problems with strings. Here is the source code:

 

#include <iostream.h>

#include <string>
//#include <bits/stringfwd.h>

 

int main ()
{
 cout << "Hola!" << endl;

 

 string pepe;
 pepe = "Hola con string";
 cout << pepe << endl;

 

 return 0;
}

Easy, isn't it? Yhis is what gcc tells me:

 

bash-2.02$ g++302 hello.cpp -o hello.exe
hello.cpp: In function `int main()':
hello.cpp:8: `string' undeclared (first use this function)
hello.cpp:8: (Each undeclared identifier is reported only once for each
   function it appears in.)
hello.cpp:8: parse error before `;' token
hello.cpp:9: `pepe' undeclared (first use this function)

Can somebody help me? I have tried including "bits/stringfwd.h" (where I have found a typedef defining string) but still have the same problem. Somewhere in this mailing list I have read about putting std::string and it seems to work, but the problem is I have to migrate a lot of source files from Linux(Mandrake) where previous program works to Tru64 machine and there are lots of string defined and change all is goiung to be a lot of work, so I hope another way to do this can be possible.

 

Thnaks in advance:
