Having built the latest trunk version all is working as expected.
Thanks

Subject: [Motion-user] ioctl sign-extension warning on FreeBSD
Message-ID: <e92918ae-ded7-434a-9751-10a1d801e...@stuyts.nl>
Content-Type: text/plain; charset=utf-8
Hi,
I?m running Motion 4.0.1 on FreeBSD 10.3-STABLE amd64. I have four ipcams and
one webcam (Logitech C920) connected and everything works fine except for one
thing: the console gives a continues stream of messages like this:
May 26 13:42:11 aurora kernel: WARNING pid 40273 (motion): ioctl sign-extension
ioctl ffffffffc058560f
May 26 13:42:11 aurora kernel: WARNING pid 40273 (motion): ioctl sign-extension
ioctl ffffffffc0585611
May 26 13:42:11 aurora kernel: WARNING pid 40273 (motion): ioctl sign-extension
ioctl ffffffffc058560f
May 26 13:42:11 aurora kernel: WARNING pid 40273 (motion): ioctl sign-extension
ioctl ffffffffc0585611
? etc
It seems to come from the USB camera, because these message are gone when I
disable it. I can?t find which call is causing this warning message. It seems
to be harmless except that it?s filling up my log files in high tempo.
Any ideas for solving this problem?
Thanks,
Ben
