[regex] Using Boost.Regex rather than std::regex with VC++

[Ahmed Charles]

I'm using VC2010, which provides an implementation of std::regex/std::tr1::regex and boost gladly uses this implementation rather than it's own. I'd like to turn this off, so that I get the boost version when including:

#include <boost/regex.hpp>

Thanks in advance.

This may not be an answer you want, I do not know the regex library,
but maybe Boost.Xpressive still uses the normal Boost-side code since
it uses regex, at the very least the static version does.

This does give you the boost version.

Maybe through ADL it doesn't in his code? Ahmed, can you give us a
small snippet example of where you call a regex function and the one
you didnt expect is called?

boost/regex.hpp *always* provides the Boost version (in namespace boost::).

boost/tr1/regex.hpp provides the std:: version if it's available, otherwise
falls back to the boost version (in namespace std::tr1::).

HTH, John.

Sorry, I must've messed it up somehow. Now I'm getting the boost version. Thanks.
