ok, I disabled the "werror" compiler flag, but there's another error:

that commit is breaking the code: https://github.com/andoma/tvheadend/commit/4ca5dda14a0e4fc7a78886e7a73058be96e3dad2

if I revert that commit, the code is compiling fine (except the warnings above)

It's 2.6.32.6
Not the newest, I know. But I'm using the latest firmware by Synology.
Is there anything you can do about that?
Maybe a switch for older kernel versions?

Are there any consequences, if I ignore the warnings?

there has been a commit (7d31b784) this morning that could solve your first compile warning. Can you check to see it that first warning is now gone?

If we need to add switches to the code for all variations and kernels then it becomes unreadable. So I would suggest that you maintain a set of patches that needs to be applied to the main branch in order to compile tvheadend on your specific hardware. And I would suggest to maintain them on github so that other people can also see/use them.

yes, that commit helped - thanks!

Sure... But ehm, sorry for the stupid question: where do I have to put patch here: https://github.com/andoma/tvheadend?

Not that much:

#ifndef _DVBVERSION_H_
#define _DVBVERSION_H_

#define DVB_API_VERSION 3
#define DVB_API_VERSION_MINOR 2

#endif /*_DVBVERSION_H_*/
