I have a DLL communicating with an external device via Ethernet and a main program with a Qt-GUI for controlling the device. The communciation runs in a different thread than the main program. Qt provides signal/slots across threads, but as I understand it, I have to use the QThread library for it to work. In the DLL I use boost signals and slots and the main program also receives boost signals and then emits Qt's signals to update the GUI, etc. The reason to not use Qt in the DLL was to not force other programmers to use Qt if they want to write their own control application for the DLL. However, I am getting in trouble with synchronization of the threads now
Are you aware that Boost.Signals is not thread-safe? It sounds like you are accessing a boost::signal from multiple threads. - -- Frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFH6rPR5vihyNWuA4URAoKiAJ9f/VObZfUPTpVvK83d+BxPCg4lQQCgltkb uVYYyAPx++Bf2Gtl3ZzJn+k= =uFjp -----END PGP SIGNATURE-----
