Were there any note lines from the compiler associated with this? The warning message can't actually be taking place on this line. Another thing I'm wondering is why your compiler shows this warning - and mine does not. I've seen this before with uninitialised variables too where you get a warning and I don't. > but because it's in the sample code, it pretty much never gets rebuilt > for me unless I basically do a "git clean" to get rid of everything, > so I don't normally see it for any normal pull. > > So I've ignored that one warning, although I've actually been tempted > to just remove the sample because of it. > > Adding David and Al to the cc just in case they have some simple fixup > for it that is likely to work across different user headers. > > I considered just adding a > > struct foo; > > declaration, but the whole thing is incredibly ugly. Yeah - I'm not sure the best way to deal with this. The problem being that userspace may have a conflicting definition - or no definition at all - and I need to use the one from the kernel in preference as that may have changes in it that aren't yet reflected in userspace. I'd rather not remove the sample if I can avoid it as I use it occasionally, but maybe I should switch to relying on glibc. David
