Quite some time ago I found a brillant and extensive article about linkers from Ian Lance Taylor. In part 13 he says: "There are some special challenges when using C++", and he is definitely right. I would like to elaborate on what theses challenges are and how the linker can be a serious trap for C++ developers. I learned it the hard way by spending hours and days on bug-hunting. Maybe this article will help others to avoid the frustration.
