My mistake, or did something change/break?

It looks like you now need itr->path().leaf() or boost::implicit_cast(*itr).leaf() ( http://beta.boost.org/doc/libs/1_36_0/libs/filesystem/doc/reference.html#Cla... )

As I recall, this change was part of optimization efforts to make iterating faster by caching the file_status.

Also, it was decided that some of the names for path decomposition functions were confusing, particularly branch and leaf, so they were changed. The new path decomposition table suggests that you should now be using filename() instead of leaf(): http://beta.boost.org/doc/libs/1_36_0/libs/filesystem/doc/reference.html#Pat... (But it's likely backwards-compatible, so you shouldn't need to.)

Yes, that's the theory. But it looks like 1.36.0 inadvertently renamed basic_directory_entry::leaf without providing backward compatibility.

I'll try to post a hotfix for that. Since basic_directory_entry::leaf is deprecated anyhow, my initial reaction is that it should have been left alone.

I would also appreciate a hotfix for this as this change is breaking a project that I am hoping to release soon. Is there an alternative solution I can use that will work in both 1.36 and earlier versions? I tried both filename() and path().leaf, but these do not work in 1.33. Thanks, Anthony
