First of all Asio comes as stand alone library outside of boost namespace. So, you may just use it as is or use namespace renaming: #ifdef USE_BOOST_ASIO #include <boost/asio.hpp> namespace netio = boost::asio; using boost::system::error_code; using boost::system::system_error; #else #include <asio.hpp> namespace netio = asio; using asio::error_code; using asio::system_error; #endif And then just relate to netio::... so you would keep an ability to upgrade to boost asio in future. This is the way I build CppCMS conditionally using Boost 1.33.1 and Asio or boost 1.35 and above only. > I believe I can make both versions > co-exist if I can manage > to rename boost 1.35's namespace to something like > boost135. > Take a look on a script I had written once: But note! boost 1.35 and 1.34 are not compatible nither ABI nor API. So you **must** not mix them in same module! This may be very tricky. So you can't use boost in interfaces between modules that use different versions of boost. Artyom
