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"?
You seem to instantiate Finder::parseFiles without providing (object) code for it. As you example is incomplete and irreproducible we can only guess. Maybe you forgot to link to another library. Maybe you forgot a source file.
No other libraries needed, no source file missing: the Makevars file somehow resembles application's Makefile!
