boost::program_ options

[zade]

Hi all
boost::program_ options needs be builled into libraries, static or
dynamic. I use MSVC7.1 to build the boost::program_ options for my
project .In my .cpp file , I write:

namespace po = boost::program_ options;

struct CommandLinePars er
{
CommandLinePars er()
:desc("options" )
{}
po::options_des cription desc;
po::variables_m ap vm;
};
But the compiler says error:
compiling....
Linking to lib file: libboost_progra m_options-vc71-mt-gd-1_33_1.lib
Linking...
commandlinepars er.obj : error LNK2019: unresolved symbols "public:
__thiscall
boost::program_ options::option s_description:: options_descrip tion(class
std::basic_stri ng<char,struct std::char_trait s<char>,class
std::allocator< char const &)"

it is clear that the lib"libboost_pr ogram_options-vc71-mt-
gd-1_33_1.lib" is linked, so why??

Thanks

The question is OT here, you should ask in a Microsoft related ng.
Anyway, have you built your libraries with the same version of the
compiler that you are using for your program? Are you linking the
correct version of the libraries (i.e., same threading model, same Debug
information, and so)?
