Re: [eigen] Tutorial example does not complie

[Carlos Becker <carlosbecker@xxxxxxxxx>]

Hi Mani. This is probably because USING_PART_OF_NAMESPACE_EIGEN has been removed. So just #include the necessary files and do 'using namespace Eigen;'

What version of eigen are you using to compile that? If it is the dev branch then try reading the dev tutorials.

Cheers.

 Hi,

I'm trying to get the following code to work:

#include <Eigen/Core>

// import most common Eigen types
USING_PART_OF_NAMESPACE_EIGEN

int main(int, char *[])
{
Matrix3f m3;
m3 << 1, 2, 3, 4, 5, 6, 7, 8, 9;
Matrix4f m4 = Matrix4f::Identity();
Vector4i v4(1, 2, 3, 4);

std::cout << "m3\n" << m3 << "\nm4:\n"
<< m4 << "\nv4:\n" << v4 << std::endl;
}

But I get the following error during compilation:

test_eigen.cc:3:1: error: ‘USING_PART_OF_NAMESPACE_EIGEN’ does not name a type

Any help?

I'm using gcc 4.5.0 20100610.

Thanks,
