We MIGHT have some missing files? I am about to convert to boost 1.32 I am still on 1.31. In the 1.31 zip file I downloaded (and am using), the header does not exist in the utility dir.
That's 'cause 'result_of' was introduced in 1.32.
I grepped the boost tree for result_of and only found one comment in transform_iterator.hpp which is stated as a question ("do we need to adjust the way function_object_result is computed for the standard proposal (e.g. using Doug's result_of)?") (line 64).
The link to the web page you sent me points to a HPP file. This file does not seem to exist in utility. For experimenting, I copied the file referenced in the page below to boost\utility. It complained on the line
#include <boost/mpl/has_xxx.hpp>
That has_xxx.hpp does not exist.
Again, it does in 1.32.
Thanks you *very much* for help here. This issue is pushing me to convert to 1.32 (which is good- I am doing that NOW). And without help from everyone who is added thoughts, I would still be in the bicycle shed. (I still am but I now see the door). :) Once I get converted and get my code working, I will post to this list a quick how to on what the resolution to the original question was (this way other folks can find the solution in the future by searching mail archives). ****************** SEPARATE THREAD: It would be nice if boost doc pages pointed to a WIKI or something for people to add things to the documentation (not officially added mind you- just ammendums)(similar to how people can comment on products on amazon.com for example) . I.e. once I get code working on how to deduce return type from a lambda functor, it would be nice if I could put that info someplace easy for others to find. OR- Is the solution for me to write up a page of documentation and simply request it be added to the lambda documentation? (which raises the issue)- is there any process for this? Thanks Again Guys. It is the people that give boost the real "boost" :)
