Hello! This is actually a problem of Wt, not of code using Wt.
See test case. It does not use boost.signals directly. I can compile this test on Ubuntu Natty and Debian Squeeze: g++ -lwt -lwthttp 900354.cpp -o 900354 Errors on Ubuntu Lucid (e.g., undefined reference to `boost::signals::detail::slot_base::create_connection()') Errors on Debian Squeeze with manually built Wt 3.2.0. (undefined reference to symbol 'boost::signals::trackable::~trackable()) I'm suspecting fresh Ubuntu Oneiric to fail. Can anyone test this? 3.2.1-1~natty~pgquiles1: no errors Natty with ppa https://launchpad.net/~pgquiles/+archive/wt/+build/2618285 no errors Maybe, it is a bug of some Wt version, not of Debian or Ubuntu packages. ** Attachment added: "test case" https://bugs.launchpad.net/ubuntu/+source/witty/+bug/900354/+attachment/3171652/+files/900354.cpp -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/900354 Title: libwt requires an explicit link to libboost_signals To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/witty/+bug/900354/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
