i have switched elementary os , installed sublime text editor. wrote basic hello world program in c++ check working. , error.

/tmp/cc3pmvft.o: in function `main': source.cpp:(.text+0xa): undefined reference `std::cout' source.cpp:(.text+0xf): undefined reference `std::basic_ostream<char, std::char_traits<char> >& std::operator<<  <std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*)' source.cpp:(.text+0x14): undefined reference `std::basic_ostream<char, std::char_traits<char> >& std::endl<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&)' source.cpp:(.text+0x1c): undefined reference `std::ostream::operator<<(std::ostream& (*)(std::ostream&))' /tmp/cc3pmvft.o: in function `__static_initialization_and_destruction_0(int, int)': source.cpp:(.text+0x4a): undefined reference `std::ios_base::init::init()' source.cpp:(.text+0x59): undefined reference `std::ios_base::init::~init()' collect2: error: ld returned 1 exit status 

the hello world program was,

#include <iostream> using namespace std;  int main(){      cout << "hello world!" << endl;      return 0; } 

i have searched answer in google , stackoverflow couldn't find solution.

you should compile c++ compiler, not c, g++ example.

instead of

gcc source.cpp 

do this

g++ source.cpp
