no dvb (cx88) modules after kernel recompile

Hi,

I'm just setting up a new box as dvb-s streaming server. I got an Hauppauge Nova-s hd-s2 card. After researching a bit, the installation was quite easy with the drivers from linuxtv's mercurial (ebuild v4l-dvb-hg). All went fine, the needed modules were built ( cx88* ) and loaded at boot. Now, after recompiling my kernel, the ebuild just won't build the drivers again. It's running fine with no errors at all. It builds all the other kernel modules for the various dvb cards, but just not the cx88*. I tried various mercurial repos out there. All are doing just fine, building kernel modules but just not the one i need. The source files for the cx88 modules are there, when portage gets the sources from linuxtv it definitely gets the cx88-source files, but it wont compile them.
I tried cleaning up everything (modules from /lib, sources from portage), but it won't work at all. The only thing i did with the kernel was deselecting nvidia framebuffer support, since i wanted to install the nvidia-drivers. Nothing more. I'm stuck right now, since I have no idea at all on what to do or where to look. Does anyone have any ideas or hints on what the problem might be?

Any help is very much appreciated!
Thanks,

Simon

copy your .config file somewhere safe - then in the /usr/src/linux dir type make mrproper - which will clean the kernel source clean for you, copy your config file back and do make oldconfig && make && make modules_install && make install

you could always do make menuconfig before you clean the kernel and make sure the cx88 drivers are compiled as modules and not built it, i had to put a line in autoload modules for mine to ctually show up and work

Thanks for your answere,

the problem is, that I don't want to build the modules shipped with the kernel, since they don't support my card right now. I use the drivers from linuxtv. The ebuild v4l-dvb-hg will compile these drivers against the kernel, except it doesn't build the cx88-drivers. (Conexxant C2388-based cards).

kernel drivers seem to work on my hvr-1100 card - strange

yeah, for that card they do. the nova-s2 hd-s2 is nearly the same card as the hvr-4000 (kind of a lightweight version). However the kernel doesn't recognize the card yet. (It's said that it will be supported in 2.6.28 however). Also AFAIK the kernel doesn't properly support DVB-S2 yet, which I need for watching HDTV. So at the moment the only way I can use this card is by using the mercurial drivers...

I think they changed the way that the v4l-dvb-hg builds in the repository.

I'm also trying to figure this out and I'm not sure what to do.

on a somewhat related note:

anyone got dvb-radio or (analog) fm-radio to work with this card (HVR-1100) ?

many thanks in advance
