Hello i have a problem, when i ported my programm from linux 64bit to windows 32bit.

i have the class

Code: Select all

#ifndef Test_H_
#define Test_H_

#include <Eigen/Core>
#include <Eigen/Eigenvalues>
#include <Eigen/Geometry>

#include <boost/shared_ptr.hpp>
#include <vector>

#include <ClassWithEigen.h>

class Test{
public:

      Eigen::Vector2d point;

   std::vector<Eigen::Vector2d> array:_of_directions;
   std::vector<ClassWithEigen::Vector2dPoints> points;
   void DoSomething(const Eigen::Vector2d& line_origin);
};

typedef boost::shared_ptr<Test> TestPtr;


#endif /* Test_H_ */

then i want to initialize this Test class in my main

int main(){
TestPtr test_ptr = TestPtr(new Test());
}

If i run this on my windows System i get following Error


i tried all of this

Code: Select all

#define EIGEN_DONT_ALIGN_STATICALLY
#define EIGEN_DONT_VECTORIZE
#define EIGEN_DISABLE_UNALIGNED_ARRAY_ASSERT
#define  EIGEN_DONT_ALIGN

but i still get the runtime error above

Can u help me ?

Make sure these #define appear before including any Eigen header. #define EIGEN_DONT_ALIGN_STATICALLY should really be enough.

A better solution would be to introduce a new type:

Code: Select all

typedef Eigen::Matrix<double, 2, 1, Eigen::DontAlign> Vector2du; // 'u' for unaligned


and use Vector2du for your class members and in your STL containers, and Vector2d everywhere else. This way you don't completely give up on vectorization.

i tried to use this and added this on every header at the top

Code: Select all

#ifndef TEST_H_
#define TEST_H_
#define EIGEN_DONT_ALIGN_STATICALLY

#include <Eigen/Core>
#include <Eigen/Eigenvalues>
#include <Eigen/Geometry>
...

but still get this error

That's very strange. What if you add the following at the top of your files:

Code: Select all

#ifndef TEST_H_
#define TEST_H_

#ifdef EIGEN_CORE_H
#error eigen already included
#endif
#define EIGEN_DONT_ALIGN_STATICALLY

#include <Eigen/Core>
#include <Eigen/Eigenvalues>
#include <Eigen/Geometry>
...

thank you that was helpfull

i oversiew one Eigen/Core include
