Well, no, for fairly obvious reasons. LD simply doesn't "find the references" in .o object files like it does with libraries. All .o files passed to LD are linked in full, because that's what the user is explicitly telling it to do (and traditionally a .o file only contained ONE chunk of linkable object, so it's fundamentally all-or-nothing). A library is different - it's a collection of .o chunks, and traditionally an ordered one at that. What LD does with a library is to examine each chunk in turn, look to see if it resolves any of the outstanding undefined symbols, and links it in if and only if it does. So there is never a retrospective "go back and examine the libraries to see if we need any other bits" operation. Items are always linked in the order they appear in the command. This also means that it actually matters quite a lot what order you construct your library in!
