Difference between GNU and ICC compilers : command line warning #10370: option '-std=c++11' is not valid for C compilations

I am having a hard time compiling a bit of c++ code using intel compiler, while GCC compiler does the job without errors.

Consider the following main function:

Main.cpp

#include <iostream>
#include <stdlib.h>
#include <vector>
#include <stdio.h>
#include "my_func_data.h"
int main()
{   
    my_func_data dataFunction;
    dataFunction.vec.push_back(1);
    dataFunction.vec.push_back(2);
    dataFunction.vec.push_back(3);
    dataFunction.vec.push_back(4);

    for(int i=0;i<4;i++){
        printf("%f\n",dataFunction.vec[i]);
    }

 return 0;
 }

where my_func_data.h is a structure that has to be in a separate header file (for the purpose of demonstrating the issue).

#ifndef my_func_data_H_
#define my_func_data_H_

#include <stdio.h>
#include <stdlib.h>
#include <vector>

typedef struct 
{   
    std::vector<double>vec;
} 
my_func_data;
#endif

Now I load two compilers and try to compile the two functions using each.

1st using gnu compiler:

module load compiler/gnu-6.2.0
g++ -std=c++11 Main.cpp  my_func_data.h -o main
./main
1.000000
2.000000
3.000000
4.000000

Next using intel compiler

module load compiler/intel-15.0
icc -std=c++11 Main.cpp  my_func_data.h -o main
icc: command line warning #10370: option '-std=c++11' is not valid for C compilations
my_func_data.h(6): catastrophic error: cannot open source file "vector"
  #include <vector>
                   ^

what could prevent ICC compiler from compiling the code? Moreover, should I embed the structure my_func_data in the main function it compiles and executes all right.

Thank you in advance for any insights!

icc is the C compiler. The C++ compiler is icpc.

This is similar to gcc vs. g++.

Problems:

  1. -std=c++11 is not a valid compiler option. See the list of valid compiler options.
  2. icc treats .h files a C source files, not C++ source files.

  3. You don't need to use my_func_data.h in the command line. Simply use:

    icc Main.cpp -o main
