Hi, i'm an eigen noob. And i get the following errors when i test an eigen sample program,as follow:

#include <iostream>
#include <Eigen/Dense>
#include <Eigen/Sparse>

using namespace Eigen;
using namespace std;

int main()
{
MatrixXf m = MatrixXf::Random(3,3);
m = (m + MatrixXf::Constant(3,3,1.2)) * 50;
cout << "m =" << endl << m << endl;
VectorXf v(3);
v << 1, 2, 3;
cout << "m * v =" << endl << m * v << endl;

Matrix<double, 1, Dynamic> mat(1,3);

for (int i = 0; i < 3; ++i)
{
mat(i) = 1.0 * i;
}

cout<<"mat="<<endl<<mat<<endl;

Matrix<double, 1, Dynamic> mat1(1,3);
mat1 = mat;
cout<<"mat1="<<endl<<mat1<<endl;

}

if i comment on the line #include <Eigen/Sparse>, it will run okay; otherwise,

it has the following errors.


Additionally, my development platform is msvc2008 professional, intel c++ compiler (v10.1.021) on window 7
and using vc++ compiler, none errors occur!!!

Can anyone give me some help? tks

Moved to Eigen forum.

since I cannot reproduce, can you tell me whether changing the line 34 of Eigen/src/SparseCore/SparseTranspose.h to:

EIGEN_SPARSE_PUBLIC_INTERFACE(Transpose<MatrixType> )

fixes the issues? (note the additional space) thanks.

Refer to the following solution:
http://eigen.tuxfamily.org/bz/show_bug.cgi?id=419

it works fine now!
