Artyom, I tried your script on 1.39 and it worked flawlessly. Thank you! Igor On Tue, Jun 23, 2009 at 5:24 AM, Artyom <> wrote:
I need to use two versions of boost in my application. One the libs I link against is statically linked against boost 1.34 and I'd like to use 1.35's asio library.
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 http://cppcms.sourceforge.net/ 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:
http://lists.boost.org/boost-build/2009/05/21911.php
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.
