Compiling eigen in Dev-C++ and windows

I am trying to use Eigen library on Windows with Dev-C++. I am using the "Getting started" program:

#include <iostream>
#include <Eigen/Dense>
using Eigen::MatrixXd;
int main()
{
  MatrixXd m(2,2);
  m(0,0) = 3;
  m(1,0) = 2.5;
  m(0,1) = -1;
  m(1,1) = m(1,0) + m(0,1);
  std::cout << m << std::endl;
}

But I obtain the following Compile Log:

Compiler: Default compiler Building Makefile: "C:\Dev-Cpp\tsesn\Makefile.win" Executing make... make.exe -f "C:\Dev-Cpp\tsesn\Makefile.win" all g++.exe -c main.cpp -o main.o -I"C:/Dev-Cpp/lib/gcc/mingw32/3.4.2/include" -I"C:/Dev-Cpp/include/c++/3.4.2/backward" -I"C:/Dev-Cpp/include/c++/3.4.2/mingw32" -I"C:/Dev-Cpp/include/c++/3.4.2" -I"C:/Dev-Cpp/include" -I"C:/Dev-Cpp/eigen"

How can I solve the problem?

I'm afraid that the compiler in Dev-C++ (http://www.bloodshed.net/dev/devcpp.html) is ancient, and unsupported by Eigen (http://eigen.tuxfamily.org/index.php?title=Main_Page#Compiler_support). Note the version numbers in there.

You can use a way more modern IDE such as QtCreator (http://wiki.qt.io/Category:Tools::QtCreator), or any other that ships a newer, compliant compiler.
