Yep, I used c++filt as well and found out the exact function. But still 
I can't figure out the problem.
Here is the actual (simple) code:

	Finder *f = new Finder();
	f->parseFiles(str_g, str_f, str_s);

where the three strings contain path-to-files.
What do you exactly mean with "...without providing (object) code for it"?

No other libraries needed, no source file missing: the Makevars file 
somehow resembles application's Makefile!
