Boost.Locale testing for particular backend

Is there a way to check (preferably at compile-time or at configure-time) whether the Boost.Locale library is compiled with support for particular backend (i.e. ICU)?

Solution

  • Boost.Locale provides this:

    std::vector<std::string> boost::locale::localization_backend_manager::get_all_backends() const

    This will list all the backends available. E.g., 

    localization_backend_manager lbm = localization_backend_manager::global();
auto s = lbm.get_all_backends();
for_each(s.begin(), s.end(), [](string& x){ cout << x << endl; });

    will print

    icu
winapi
std

    If Boost.Locale wasn't built with ICU support, it will list only the two last lines.

    You can use this in a configure script and compile a .cpp that accepts a backend as a parameter and checks whether it is supported.
