QUESTION
I try to use a interface realization through a generic class. Wondering on some abstraction magic, but get compiler errors with this approach.

QUESTION
I'm currently trying to solve a particular eigenvalue problem (so-called gyroscopic eigenvalue problem) with large, sparse matrices (from FEM dsicretization). The programming language is C++.
The standard reference for EVP is ARPACK. Alas, it implements only "classical" Arnoldi processes, which is not suited for such problems (c.f. Structure Preserving Methods).
Recently I've found this Algorithm 961 reference, which also provides some code - in FORTRAN! So i've tried to include the DGHUTR routine in C++, to no avail. Below is the MWE, which is an adaptation of the test for DGHUTR (TDGHUTR.f) in C++:

Answered 2017-Feb-26 at 10:51I think I have found the source of the problem which has been plaguing me.
The dependence of the values received by the fortran routine on the optimization flags was kind of
a hint that there might be something wrong with how the stored variables are interpreted by C++ and
FORTRAN.

I tried playing with the compiler flags for the libraries.
When I fetched SLICOT I took the source and a library precompiled with gfortran for linux (slicot_linux_gfortran.tar.gz
).
This latter one came with a make.inc with OPTS = -O2 -fpic -fdefault-integer-8
The SHHEVP routines contained the following comment in the make.inc
