I just downloaded the latest version on the web site. I've never really used CVS before, but I tried to grab what appeared to be all the relevant files for type_traits. Now, when I try to use boost::function, I get all this: /usr/local/include/boost/function/function_base.hpp:151: parse error before `>' token /usr/local/include/boost/function/function_base.hpp:153: template argument 1 is invalid /usr/local/include/boost/function/function_base.hpp:153: `type' is not a class or namespace /usr/local/include/boost/function/function_base.hpp:153: ISO C++ forbids declaration of `type' with no type Which points to a line that contains is_stateless<>, which I assume is part of type_traits. So, could someone, in simple terms that a 5-year-old could understand, tell me how to get the latest version of type_traits from CVS? Do I actually need to download CVS software, or can I do it all through the web interface? Thanks. Dave [Non-text portions of this message have been removed]
