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@@@boos t@@@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
Did you build boost from a "64 Bit" Command Prompt? Using the normal "Visual Studio Command Prompt" sets up for 32 bit compiles. Using the "Visual Studio 64 bit COmmand Prompt will compile 64 bit binaries. This is how I usually do it and it works just fine. Mike Jackson
