If it is not printed and you use make to compile, try VERBOSE=1 make That way you can check that you are really linking the libraries you think you are linking. Next, when you see qpid-proton-cpp truly is in the list of libraries linked, you can try checking the symbol is present in the file (command from https://stackoverflow.com/questions/34732/how-do-i-list-the-symbols-in-a-so-file/48122967#48122967 ) nm --demangle --dynamic --defined-only --extern-only path/to/libqpid-proton-cpp.so | grep reconnected and that should print something like 000000000002b760 T proton::connection::reconnected() const (the T after the address means that the symbol is in the text (code) section and it is global (external)). Also, perhaps try 0.39.0 in case anything has actually changed. > It can't hurt, I guess. -- Mit freundlichen Grüßen / Kind regards Jiri Daněk
