Cilk Plus in Ubuntu

Question

I am trying to test the following code in Ubuntu 15.04.

#include <iostream>
#include <cilk/cilk.h>

using namespace std;

int main() 
{
    cilk_for(int x=0; x<10; x++) 
    {
        cout << x << endl;
    }
    return 0;
}

I am getting the following error. It seems that g++ command can detect cilk plus but cannot compile somehow.

anirban@anirban-XPS-8500:~$ g++ test_cilk.cpp -lcilkplus -lcilkrts
test_cilk.cpp: In function ‘int main()’:
test_cilk.cpp:8:11: error: expected primary-expression before ‘int’
  cilk_for(int x=0; x<10; x++) 
           ^
test_cilk.cpp:8:20: error: ‘x’ was not declared in this scope
  cilk_for(int x=0; x<10; x++) 
                    ^

Answer 1

Your g++ command is incorrect. It should be

g++ test_cilk.cpp -fcilkplus -lcilkrts
                   ^
