calling ROOT routines in FLUKA

Dear all,
        I am trying to call someROOT routines inside a source.f file.
I have modified the example http://www.fluka.org/fluka.php?
id=examples&sub=example3&node=4 and everything runs fine.
But not being acquainted with creating classes, dictionaries, makefiles...I
modified that mechanically.

   Since I am filling a simple TTree, I decided to simplify the procedure (no
dictionary anymore). But I make something wrong in the Makefile.
I have no idea if I should tell to use ROOTLIBS and how, or if the mistake is
another.

I oversimplified the called routines (just a printf), but I still get the same
error.
Could someone give a look, please?

Thanks a lot,
regrads,
bye,
Francesca

I have:

1. a file FluLib2.cpp (in attachment)
2. a source.f containing the line

CALL myuserini()

3. the Makefile (in attachment)

The output, when I run the makefile, is

Generating Library
FluLib2...

my-gcc -c FluLib2.cpp -pthread -m64 -
