Hi, try bjam --toolset=msvc-9.0 address-space=64 this should produce 64bit libs.

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 > & __cdecl boost::basic_regex >::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 #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

Are you invoking the bjam with the "Visual Studio 64Bit command Prompt"? Mike Jackson
