Lu) It seems gas-950822 doesn't treat common symbols right. Does the newer snapshot still have this bug? BTW, I tested it under i486-linux. It only takes you a minute to note what you think is incorrect about the program. Please do that, rather than making me figure out what the problem is. Thanks. In this case, I assume that you think that the common symbol in the object file should cause the object in the archive to be brought in. That's the way in works in a.out, but it is not the way it works in ELF. In ELF, objects are only brought in from archives to fill references by undefined symbols. However, interestingly, I tested the program on Irix 5, UnixWare, and Solaris, and, on Solaris, it works the way it does in a.out. I assume this is for SunOS compatibility. It happens to contradict the Solaris linker documentation: ``For an archive library, only those routines defining an unresolved external reference are loaded.'' Ian
