desktopvideo_10.7a18_amd64.deb wont build on 4.6 kernel

Hello,
trying to install desktopvideo_10.7a18_amd64.deb on a Debian Sid box with current Liquorix kernel 4.6-2.dmz.2-liquorix-amd64. Cannot get it to build module. Doesn't work on current debian vanilla kernel 4.6.0-1-amd64 either..

See attached log file

any help appreciated...

Hi Dave,

Thanks for providing the DKMS build logs.

The errors shown match an existing ticket which describes issues building the DeckLink modules on Linux 4.6+, and a correction for this issue will be available in a future Desktop Video release.

While this issue is addressed I recommend using an earlier kernel version in order to continue using the DeckLink devices.

Sincerely,

-nick

Thank You, Sir!
