Re: [Cppcms-users] Boost locale with icu backend static linking.

[Stanimir M. <sta...@zo...>]

After i made a simple example for linking with boost_locale statically
and building it on a clean machine the problems still exists.
It could be something with the link order or something else, that i
just can't see.

Here are some info for my environment:
Ubuntu 12.04 server x86_64
g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 - installed from the repository
boost 1.49 - compiled from source and installed

$ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

Here is the example that fails to compile:

#include <boost/locale.hpp>
#include <boost/locale/date_time.hpp>
#include <boost/locale/info.hpp>
#include <boost/locale/localization_backend.hpp>

#include <string>

int main(int argc, char* argv[])
{
  using namespace boost::locale;
  generator gen;
  std::locale l = gen("bg_BG.UTF-8");
  std::locale::global(l);
  std::cout.imbue(l);
  boost::locale::date_time date = boost::locale::date_time();
  std::cout << "info: " <<
std::use_facet<boost::locale::info>(l).country() << std::endl;
  std::cout << boost::locale::as::date << date << std::endl;
}

The expected output must be:

info: BG
07.08.2012

Compiling with the following command line for dynamic linking works:
g++ main.cpp -o test -lboost_filesystem -lboost_thread -lboost_system
-lboost_locale -Wl,-Bdynamic

The problematic link for static is:
$ g++ -Wl,-Bstatic -lboost_system -lboost_filesystem -lboost_locale
-static main.cpp -o test

Here is the output of the command line for static:
