Hi all

i'm tryin to get this card installed but without any luck.

It seems there are no good drivers available anymore except for: https://bitbucket.org/powARman/v4l-dvb-saa716x/overview but i get compile errors

the card:

Did try make clean, make distclean etc

any ideas how to get this card to work ?

You're experiencing the joy of having what they call an "out of tree" device just like I am for other devices. Meaning that the "official" Linux developers aren't involved with the driver.

While the kernel folks try very hard not to break compatibility between kernel and user space, that's not so within the kernel itself. They're constantly tweaking things, and then they go fix the things that those changes break. But it's very common that these "out of tree" drivers won't get those fixes for quite some time (if ever) because the maintainers aren't keeping up to date.

Being on the bleeding edge with Arch exacerbates this situation, especially if the out of tree developers use a distro that lags behind and/or only updates the kernel infrequently because they haven't hit the problem (yet).

So to answer your question about getting it to work, possibly the only answer is that those compile errors would need to be investigated and fixed.
