If the linker doesn't follow Y's link to Z, how is it supposed to resolve Z references? so yes, you do have to link X with Z -- that's what explicit linking requires. Following indirect links (like your Y -> Z) example is the original ld behavior. The latest binutils linkers don't do this be default. You either had to pass a flag to change how it's built during configuration (or maybe patch the linker, not sure) to restore the original behavior. John
