[Boost-users] [log] More than one module but static linking?

Andrey, the documentation of your very useful logging library says: "If your application consists of more than one module (e.g. an exe and one or several dll's) the library must be built as a shared object." As it turns out I want to use your library in such an application. However there is only one module writing to the log file. Do I still need to use the shared library? Or can I link statically if for example I don't use certain parts of the library? As far as I see there is no more information in the documentation why linking dynamically is forbidden? Boris
