boost locale support about bh

[eddelbuettel]

Quick question: Is that header-only? Can it be made header-only?

A few Boost library require linking, a few of those can be #ifdef'ed to remove some features to not require linking. But most examples still requiring linking are text / string related so I am not too hopeful here.

Can you try to find out some more details?

Besides the BH package I do include (for a unix OS) also the following,

#ifndef _WIN32
  #include <boost/locale.hpp>
#endif

As of boost 1.62 the boost/locale.hpp file includes the following:

#ifndef BOOST_LOCALE_HPP_INCLUDED
#define BOOST_LOCALE_HPP_INCLUDED

#include <boost/locale/boundary.hpp>
#include <boost/locale/collator.hpp>
#include <boost/locale/conversion.hpp>
#include <boost/locale/date_time.hpp>
#include <boost/locale/date_time_facet.hpp>
#include <boost/locale/encoding.hpp>
#include <boost/locale/format.hpp>
#include <boost/locale/formatting.hpp>
#include <boost/locale/generator.hpp>
#include <boost/locale/gnu_gettext.hpp>
#include <boost/locale/info.hpp>
#include <boost/locale/localization_backend.hpp>
#include <boost/locale/message.hpp>
#include <boost/locale/util.hpp>

#endif

The locale issue is apparent, for instance, when I try to convert non english text to lower/upper case.

That does not answer my question about the need for linking. Looking at your package I see

@LOCALE_LIBS@ -lboost_system

and that is a no-no for the BH package. No linking. Headers only.

And it is right in your own configure.ac as LOCALE_LIBS="-lboost_locale".

Sorry, can't do in BH. You can try to build on top of BH and shadow with local copies your package. Some stan related packages did that for a while, and we moved things which are in fact header-only over.

BH cannot give you all of Boost without linking. No Free Lunch. Sorry.
