Hi Folks,

I downloaded package 15947 and installed eigen from the UppHub

I followed the demo. However, I got this error when I build my project. It is in this picture index.php?t=getfile&id=6531&private=0

Please help me solve this problem. Thank you!


Best Regards
Daivd

I copied the eigen demo file from the tutorial side to put only one .cpp file in the project. It is still the same.

File is attached.


Thank you for your support!

Hello David,

You need to add Eigen package to your project, not the plugin/eigen. The plugin is utilized by the Eigen package and it will be automatically added to your package when you select Eigen package.

E.g.:

#include <Core/Core.h>
#include <Eigen/Eigen.h>


index.php?t=getfile&id=6534&private=0


Best regards,
Oblivion
