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.

It sounds like you have a partial version of Boost 1.27.0, because the is_stateless trait is in 1.27.0. You can try a partial updates using the web-based CVS, but anything more than a small update is quite tedious. First go to the browseable CVS repository at: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/boost/ You can navigate to boost/boost/type_traits, and then click on the "object_traits.hpp" header file (where is_stateless is located). Then you can look for the version that says: CVS Tags: Version_1_27_0, RC_1_27_0 Click "view" to see this version of the source code, and you can save it locally. I would still advise you to get the Boost 1.27.0 tarball again and unpack it instead of going through all of this hassle. Doug
