Question

I’ve included the Eigen headers in a C++ project in Eclipse. When I try to build I get this error:

Symbol 'Eigen' could not be resolved    Semantic Error

From what I understand, this is a linker error, but Eigen is a header-only project and thus has no library to link against. The code that throws the error follows the basic tutorial they provide, and the offending snippet looks like this:

#include <Eigen/Dense>

using namespace Eigen;

What am I doing wrong? If it helps, I’m running this on Linux. Thanks.

I was fiddling around and found that telling the Indexer to index unused headers resolved my problem.

Thanks for being on the ball guys. Kind of sorry I stumbled upon it myself.
