My humble apologies if my question is inappropriate for this list. I'm trying to build the DEV_QT branch of 21.5 from cvs. System is a fairly up to date Knoppix, which is more or less Debian testing with a smattering of unstable. It compiles with a ton of warnings but no errors, but linking fails with the following complaint. /usr/local/src/xemacs-21.5/src/moc_qt-xemacs.cpp:359: undefined reference to `__dso_handle' I imagine I'm missing a header file or a relevant include. I've done a bunch of finding and grepping to try to figure out what's missing. I seem to have a lot of executables which reference __dso_handle, including some I built on this box, but I can't find it in any header file. I would appreciate any hints that might point me in the right direction. -- Bud Rogers <budr(a)netride.net&gt; KD5SZ
