Hello Sebastian and thank you for the follow up,

I must precise that I have 2 builds of my projects:
one linking to the multi threaded static runtime (/MT) and one linking
to the multithreaded dynamic runtine (/MD).
I defined BOOST_ALL_NO_LIB=1 to disable autolinking,
and i am linking manually to libboost_filesystem-vc90-mt-s-1_36.lib
libboost_program_options-vc90-mt-s-1_36.lib and libboost_system-vc90-mt-s-1_36.lib
for the /MT variant, and to boost_filesystem-vc90-mt-1_36.lib, boost_program_options-vc90-mt-1_36.lib and
boost_system-vc90-mt-1_36.lib for the /MD variant.

For _both_ variants, I get stuck with following unresolved externals:
__declspec(dllimport) public: void __thiscall boost::program_options::detail::cmdline::set_additional_parser(...)
__declspec(dllimport) class boost::system::error_category const & __cdecl boost::system::get_generic_category(void)
__declspec(dllimport) class boost::system::error_code boost::filesystem::detail::throws

What is more suprising, is that for the dynamic version, the set_additional_parser export _does_ appear when I
dumpbin /exports ./boost_program_options-vc90-mt-1_36.lib  | grep  set_additional_parser
but the two other symbols do not appear in boost_system-vc90-mt-s-1_36.lib.

Any idea what I am getting wrong ? Beginning to feel lost.
Cheers,
Florent

Hello Florent,
To check if a symbol is exported correctly I simply use dumpbin which
is a command line tool that comes with msvc.   E.g.:

dumpbin /exports
..\boost_1_36_0\lib.x86-nt-msvc8\boost_program_options-vc80-mt-gd-1_36.lib
| grep program_options::arg

The "non dll-interface" warnings are OK, but am I missing something or
are you not linking against boost_program_options-*.lib ?  I have to
say that I currently don't use auto linking maybe you should try
adding all libraries manually and turn off the auto linking feature by
defining: BOOST_ALL_NO_LIB=1.

Regards,
Sebastian
