Thanks a lot for the suggestion. I already started wondering that it
will probably be better to ask on some other list, but before I give
up ...

... here are the libraries for 64-bit linux
    http://ol.ijs.si/~mojca/osciloskop/linker-with-libs.tar.gz

I added collect2 and "runme.sh" which should run the basic command.
However I'm not sure if what I attached is everything that is needed
to reproduce the problem ... Please let me know if I missed something.
(I'm just a basic user who has never dealt with any compiler issues at
all.)

Here is the output of my failed compilation with verbose flag (I just
learnt about its existance):
