Future of the Linux-Driver

@smv1210

Are you on 32bit?

Because I still can't get this to work on my 64bit machine.

I still can't get this to work on my 64bit machine.

Is it still not building for you? Or building but failing to work?

I could try it under 64 bit O/S, but probably not for a day or so ...

[smv1210]

Are you on 32bit?

Yes I am.

@Andy

Mythtv works just fine with the driver : back-end configuration, channels scanning and switchover (Eutelsat W4, 36.0E).

Thank You a LOT!

It seems to build ok. But I get the error which I mentioned earlier when I modprobe.

Just the one symbol error, or lots more? If just one I can check it's being exported properly.

Any chance you can try installing 32bit into a spare partition? I can try 64 bit, but it'll take me a while to download and install it, actually my Xen host is already 64bit but I'd rather not risk breaking it because it already has a customised kernel!

[smv1210]

I also can try 64bit Ubuntu later today...

Brilliant ... spread the word ... also keep up the gentle pressure on TurboSight to release the code under GPL and get it adopted into the mainline kernel, else in a year's time we'll be back in the same boat when it breaks again ... I think Cody realises the issue, but perhaps his bosses think the Linux job is done and they can move on to new products?

Cody, as a gentelman (? ) should share his salary with You, for a certain period of time... (just a joke)

Yes that is the only error I see.

I'm sorry I don't have any spare hdd space to do a 32bit install.

Thanks again for all the effort you are putting into this.

There is my attempt with 64bit Ubuntu, unfortunately - negative one:
