Hi,

I want to use the unsupported/Eigen/OpenGLSupport module for the OpenGL bindings. Unfortunately, when I include the OpenGLSupport header in more than one object files, I get linker errors like

Code: Select all

temp/.objs/temp.o                                    In function Eigen::glRotate(Eigen::Rotation2D<float> const&)':|
include/eigen3/unsupported/Eigen/OpenGLSupport|192|  multiple definition of `Eigen::glRotate(Eigen::Rotation2D<float> const&)'|
temp/.objs/main.o:include/eigen3/unsupported/Eigen/OpenGLSupport|192|first defined here|


The minimal example is
main.cpp:

Code: Select all

#include <GL/glew.h>
#include <GL/glut.h>
#include <GL/glu.h>

#include "temp.h"

int main()
{
   return 0;
}


temp.cpp:

Code: Select all

#ifndef TEMP_H
#define TEMP_H
#include <GL/glew.h>
#include <GL/glut.h>
#include <GL/glu.h>

#include <Eigen/Core>
#include <Eigen/OpenGLSupport>


#endif


temp.cpp

Code: Select all

#include "temp.h"


Is there any way to get around this?

Thanks in advance!

fixed in the default and 3.0 branches (some static keywords were missing)

Thanks for the quick reply. I am actually using Eigen 3.0, I'll try to download the very latest version and see if it's solved.

Cheers!

Thanks for the support! With the latest development branch it compiles and links perfectly.
Cheers,
