Hi Sergio & Laurent,

Back in July, Sergio submitted a patch "Just include kernel headers" (http://www.mail-archive.com/linux-media%40vger.kernel.org/msg20397.html) which Laurent didn't yet want to apply.

Now I'm using Laurent's branch "new-api" (and the new media API to match), and w/o Sergio's patch, I get a warning:

types.h:13: warning: #warning "Attempt to use kernel headers from user space, see http://kernelnewbies.org/KernelHeaders"

With Sergio's patch and setting HDIR, I get rid of this warning. Laurent, what do you think about applying the patch now? I would ack it if I could, but I don't know how to resurrect an old patch.

As answered to Sergio, at the moment most users will build media-ctl against a kernel tree instead against installed kernel headers. I will merge the patch when the media controller code will reach the mainline kernel. It should be safe to ignore the compilation warning for now.
