string

[Mohammad shojatalab]

Hi ,
I have a simple C++ program: (test.cpp)

#include <iostream>
#include <string>
using namespace std;

int main ()
{
     string file="Hello World!";
     return 0;

}

but when I try to compile it this is what I get:
/usr/bin/gcc -o test test.cpp
/tmp/cc3PgfJI.o(.text+0x1c): In function `main':
: undefined reference to `std::allocator<char>::allocator[in-charge]()'
/tmp/cc3PgfJI.o(.text+0x31): In function `main':
: undefined reference to `std::basic_string<char, 
std::char_traits<char>, std::allocator<char> 
 >::basic_string[in-charge](char const*, std::allocator<char> const&)'

/tmp/cc3PgfJI.o(.eh_frame+0x12): undefined reference to 
`__gxx_personality_v0'
collect2: ld returned 1 exit status

these are what I have:
cpp-3.2.2-5
libstdc++-devel-3.2.2-5
compat-libstdc++-7.3-2.96.118
compat-gcc-c++-7.3-2.96.118

libstdc++-3.2.2-5
gcc-g77-3.2.2-5
gcc-gnat-3.2.2-5
gcc-3.2.2-5



Whats wrong?
