Hi Andrew: My experience is also that ldd -u often produces invalid complaints about unused direct dependencies. So I think it is a bug in ldd -u that should be reported. But until that bug (or bugs) is fixed, ldd -u appears to still be useful as an indication of a possible problem with overlinking, but you have to rely on "nm" (as you have done this time) to confirm each case where there is such an "nm -u" indication. I was also very glad to hear that your latest effort was a success, and Jerry is on the air again with our qt devices. Alan __________________________ Alan W.
