here's the programme,1.cpp:

Code:
 
#include<iostream> 
#include<string> 

int main() 
{ 
std::cout << "hello world" << std::endl; 
return(0);
} 
 
under the shell
$ gcc 1.cpp
and then appear too much unknown things~~

Code:
 
/tmp/ccL80Lex.o(.text+0x14): In function `main': 
: undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::endl<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&)' 
/tmp/ccL80Lex.o(.text+0x21): In function `main': 
: undefined reference to `std::cout' 
/tmp/ccL80Lex.o(.text+0x26): In function `main':

: undefined reference to `std::basic_ostream<char, std::char_traits<char> >::operator<<(std::basic_ostream<char, std::char_traits<char> >& (*)(std::basic_ostream<char, std::char_traits<char> >&))' 
/tmp/ccL80Lex.o(.text+0x5c): In function `__static_initialization_and_destruction_0(int, int)':
