Linker error with boost.locale and operator%

[andreas.kuechler@…]

Hi,

I recently updated to boost 1.61 with self-compiled libraries using MSVC2015 with the following build settings

.\bootstrap
.\b2 architecture=x86 toolset=msvc -j 12 --layout=tagged

The libraries are properly compiled but when I link with my application I get the following errors:

(BOOST_AUTO_LINK_TAGGED is defined globally)

debug\uniform_initialization.exe : fatal error LNK1120: 2 unresolved externals

I got a minimal working example

#include <boost/locale.hpp>

int main(int argc, char *argv[])
{
  (boost::locale::format(boost::locale::translate("Hello, {1}")) % "World").str();
  return 0;
}

The linker error occurs only if the operator% is used, format and translate alone compile and link fine. The linker error disappear as soon as I add #include <boost/system/error_code.hpp>

It is dependecy problem on Windows, autolinking of not directly dependent libraries works badly
