6124	Problem with copy_file in 1.47	morandidodo@…	Beman Dawes	"Hi,
I'm having a strange behaviour with copy_file in boost 1.47.

I've got a file with a piece of code like this:

{{{
string filename, old_filename;
...
copy_file(old_filename, filename);
}}}

It compiles, but it doesn't link. The linker says that copy_file doesn't exists:

{{{
/usr/local/include/boost/filesystem/v3/operations.hpp:303: undefined reference to `boost::filesystem3::detail::copy_file(boost::filesystem3::path const&, boost::filesystem3::path const&, boost::filesystem3::copy_option, boost::system::error_code*)'
}}}

I'm using other functions from the filesystem library, and if I don't include the ""-lboost_filesystem"" flag I got other errors, so the library is correctly found.

The boost library is not pre-compiled -- I built it by myself, but I didn't specified any particular flag to the b2.

Thanks
