Perhaps one is const and the declaration calls for non-const or vice versa? Try making your own call to the constructor elsewhere (such as in a temporary test.cpp file) and see if that triggers the linker error. Maybe also try gcc2 instead of gcc4, to see if it is a compiler pickiness problem or something else. - Alex
