Hi,

(Apologies if this gets through twice, I think my mail client used the
wrong email address the first time)

Thanks for taking the time to read through this.

First things first:

I am using Visual C++ 2005 Express Edition, I have compiled boost
version 1.32. I have included the path to the include directory and the
lib files directory. Boost is working I have managed to compile and run
a number of the other examples (including linking against the libs
created during the bjam process (eg boost.threads).

The code that has the link error was taken from:
http://www.boost.org/libs/test/doc/components/utf/getting_started/index.
html
 

--Code--

#include <boost/test/unit_test.hpp>
using namespace boost::unit_test;

test_suite* init_unit_test_suite( int argc, char* argv[] )
{
        test_suite* test= BOOST_TEST_SUITE( "const_string test" );
        return test;
}

// EOF

--End Code--

The comment at the end of the code suggests that I can compile this code
with no errors.

Now for the errors:

I know it is probably something really simple but for the life of me I
am just missing it =/.

Let me know if you need any more information.

Thanks for any advice you can give.

Peter.
