I added several different versions of Eigen to default including directory of Visual C++. But I got collapse problem when using LDLT (Cholesky decomposition) for some of the testing numerical examples.

So I want to determine which version is actually active when debugging the code.

Is there any function which can indicate the current active Eigen version number?

This answer is only a summary from the comments above:

  • At compile-time you have EIGEN_WORLD_VERSION, EIGEN_MAJOR_VERSION and EIGEN_MINOR_VERSION, you can easily embed this information in your application.

  • 3.1.91 sounds like a beta version of 3.2.

  • The version number macros are defined in Macros.h located at \Eigen\src\Core\util\.
