It's not as if the linker randomizes its inputs. Different >linkers might do things differently, sure, but I'm assuming the OP >isn't doing anything really silly such as using different linkers. My case may have nothing to do with the OP's problem. But we use gcc/as/ld for our embedded boards. Even with the completely same environment (we only have few anyway) the linked endresult can differ when compiled on different machines. It may have to do with the fact that we collect some modules in libraries and feed these to the linker. The order of the modules inside the libraries may not necessarily be the same as we delete/add/update the libraries, depending on the changed source files. But even a complete rebuild doesn't always output the same file, the changes are obvious in the according map file. But as I said that may have nothing to do with the original problem, just a fact that we have experienced. bye Fabi
