Hello, I'm currently porting a part of code to a "smaller" version of windows which runs on a real time os. The Os provides most of the windows 32 API functions but only in the "A" variant ( using only standard characters). I got everything compiled fine up to the linker step, where the linker doesn't find the wide string versions of the API calls. Is there some way to deactivate the wide string windows API in boost::filesystem V3 ? Thanks for the help. Regards, Thomas Bernard
