no, probably no. However the linker is really one of the most obscure source of
error messages in Unix-like development platforms.... so, who knows :)

use "nm -C" when trying to understand C++ linker errors ;)
Some explanation about nm's output is here:
http://www.hmug.org/man/1/nm.php (nm man page for mac I think)
We are interested to the "T" = the symbol is defined in the object file and to
the "U" = the symbol is used by this object file but not defined there.
Some help can be found at:

templates are those "things" containing angle brackets: < > so you should do a
grep -v "\<" logfile_of_linker
to see if there are multiple defined symbols which are not related to
templates....
