I am using MTL(Matrix template library) in Dev-C++ 4.9.8.0. The gcc version is 3.2.
Due to the limited disk space in the computer I did not install the VC2008 yet.
That is my simple program :
#include <iostream>
#include <stdlib.h>

using namespace std;

# include <mtl/mtl.h>
.....................................
But the complier told me that 
In file included from F:/Dev-Cpp/myproject/mtl_2_1_2_21/mtl-2.1.2-21/mtl/light1D.h

F:/Dev-Cpp/myproject/mtl_2_1_2_21/mtl-2.1.2-21/mtl/matrix_traits.h:153: `
SPARSE' was not declared in this scope

and the line in the header file matrix_traits.h is 
......................
struct sparse_tag { enum { id = SPARSE }; };
..............................
After I searched the whole directory of MTL ,no file contains the SPARSE,
The same problem occurred to the string "index_from_zero".
I am using mtl-2.1.2-21.tar.gz under windows.

And I do not know how to solve it.
Can any one with kindness help me?
