Hi!

I am trying to build a project here with Visual Studio 2008 for a 64
bit platform, but I get a lot errors like the following (building it
32 bit works fine)

1>boosttest.obj : error LNK2001: unresolved external symbol "private:
class boost::basic_regex<char,struct boost::regex_traits<char,class
boost::w32_regex_traits<char> > > & __cdecl
boost::basic_regex<char,struct boost::regex_traits<char,class
boost::w32_regex_traits<char> > >::do_assign(char const *,char const
*,unsigned int)"
(?do_assign@?$basic_regex@DU?$regex_traits@DV?$w32_regex_traits@D@boost@@@boost@@@boost@@AEAAAEAV12@PEBD0I@Z)

Here is what I did to build the libs:

bjam msvc architecture=x86 address-model=64 stage
bjam msvc architecture=x86 address-model=64 install

I tried various versions of the above lines, with other parameters, or
written differently e.g. (--toolset=msvc) but the end result did not
change.

Then I added the c:\boost\include\... and c:\boost\lib dir to (Tools
-> Options -> VC++ Directories -> Platform x64 Include and Library
files)
To simplify the problem I created a new project and created a new
Configuration for x64

-----
#include "stdafx.h"
#define BOOST_LIB_DIAGNOSTIC
#include <boost/regex.hpp>
#include <string>

int main()
{
   boost::regex pat( "bla" );
}

I can build above fine in 32 bit mode, using the same(!) lib folder.
So I assume, the created libs are 32 bit. (Can I check that somehow?)
Any ideas what I might do wrong? Or what I might do to find out where
the problem lies?

Thanks, Christoph
