Hello,

I would like to use UmfPackLU but I it seems that I'm too unexperienced including external libraries.

As described I include UmfPackLU by

Code: Select all

#include <Eigen/UmfPackSupport>

Here the problem starts with the following error:


I'm using Linux Mint 12 with installed Suitesparse and UmfPack 5.4.0 packages. The Eigen Version is current dev branch. During the Eigen installation using cmake I've got the confirmation, that umfpack is installed.

Code: Select all

-- Found CHOLMOD: /usr/include/suitesparse
-- Found UMFPACK: /usr/include/suitesparse
-- Found SUPERLU: /usr/include/superlu


Can someone help me finding my mistake?

Thanks in advance,

Peter

Eigen is a header only library. This means you have to configure umfpack for your own project (include path and linking libraries). If it is based on cmake, you can use our own FindXXX.cmake module for this step.
