Gotta love C++. Write code once, sit around for several years, wake up one day and it suddenly no longer compiles. Is there an easy way to figure out where /usr/include/signal.h is being included? It seems that "signal" in that file is conflicting with sigc::signal. I suspect there are two possibilities: * /usr/include/signal.h was recently #include'd by one of gnomoradio's dependencies. or, * /usr/include/signal.h has always been included, but a new version of g++ has determined this reference to 'signal' to be ambiguous where it had not been before. I no longer use Debian, but I will try to debug this further if I get a chance. Here's a related message on libsigc-list: http://www.nabble.com/namespace-problem-td19310347.html Maybe I ought to just s/signal/sigc::signal/ throughout the source... - Jim -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
