I checked it twice and this option simply wasn't passed to the linker. I removed both -r and -Ur from linker options and it builds again - final binary is slightly slower, but main problem (symbols from boost::asio) still persist - if this is a problem at all, of course. -- Jędrzej Dudkiewicz I really hate this damn machine, I wish that they would sell it. It never does just what I want, but only what I tell it.
