Hi to all,

I think I found a solution for this problem. You can read it on this message, at crysol.org: http://crysol.org/es/node/1082#comment-5014

Thanks.

/home/holger/Downloads/rtl2831-r2/v4l/v4l2-dev.c:371:2: error: unknown field 'ioctl' specified in initializer
/home/holger/Downloads/rtl2831-r2/v4l/v4l2-dev.c:371:2: warning: initialization from incompatible pointer type
make[3]: *** [/home/holger/Downloads/rtl2831-r2/v4l/v4l2-dev.o] Fehler 1

i replaced the config and patched successfully. I have to admit my spanish isn't really good

Hello and thanks for testing!

Please, could you paste here the full compilation log. I've not modified every file, just only the ones I need, but these may be different for you. Thanks.

Edit: Oops, sorry. The patch is malformed:

patching file linux/drivers/media/video/v4l2-common.c
patch: **** malformed patch at line 582: --- 909,908 ----

Please, wait until I fix it

Edit: done. I edited the patch by hand... bad idea Please, insert coin and try again!

Hi,
I have tried to compile the module with the patch but I still get an error. This time is the following:

Yep, you should use the config I use. All IR modules must be disabled for now. Sorry.

[gamx]

My fault. My Spanish is good but I did not read the instructions carefully enough. Sorry.
With your config file (replacing the one in the v4l directory) I manage to get a bit further but I still get an error. Am I supposed to change anything more? I am not an expert...

SOLVED !!!!!!!... sorry my english is not so good, but I paste here a comment (pending of moderation) left at metalzonix. In that post metalzonix had a recipe for ubuntu 10.10. With that recipe and the patch of crysol I tried to combine doing the following (comments in spanish):

¡¡¡ Lo conseguí !!! he combinado las instrucciones de este post con el parche http://crysol.org/es/node/1082#comment-5014

No soy experto en esto… en un probar por probar hice lo siguiente (trataré de recordarlo todo, no tomé notas porque no creía que funcionaría):

# sudo apt-get install linux-source linux-headers-$(uname -r)
# sudo apt-get install mercurial
# hg clone http://linuxtv.org/hg/~jhoogenraad/rtl2831-r2
# cd rtl2831-r2/

hasta aquí como en este post…. ahora el parche tal y como dice

# rtl2831-r2$ wget http://arco.esi.uclm.es/~oscar.acena...l_2.6.38.patch
# rtl2831-r2$ patch -p1 < kernel_2.6.38.patch

Dado que el post que habla del parche también habla de un archivo config… yo añado su descarga (aunque no se si hice algo con él, de hecho no se si vale o no)

# rtl2831-r2$ wget http://arco.esi.uclm.es/~oscar.acena...rtl2831/config

Ahora continúo como en este post

# sudo make menuconfig

Y aquí viene, creo, lo importante… deshabilité todo (salvo el apartado audio, quité las marcas a todo) y solo dejé lo que hacía referencia a RTL2831u

# sudo make clean
# sudo make
# sudo make install

Algún error por medio creo que dió, pero dió la sensación que la instalación finalizó correctamente así que… desconecté y volví a conectar el tdt usb stick zappa y…

# lsmod | grep dvb

bingooooooooooo !!! me apareció esto…

dvb_usb_rtl2831u 93776 0
dvb_usb 19240 1 dvb_usb_rtl2831u
dvb_core 90137 1 dvb_usb

Abrí VLC, desempolvé mi archivo channels.conf y…. viendo la tdt en Ubuntu 11.04.

Rogaría a metalzonix, que tú si que sabes, que depurara o diera sentido a lo que he escrito en este comentario, con el fin de ver si he recordado algo mal o he hecho algo de más o de menos.

GRACIAS.

[gamx]

Finally it works for me. I had to disable V4L (on top of what was already disabled in the config file mentioned above) and now it seems to work.
Thanks to all,

Gamx

[Happyl]

yeah, nice work dudes...finally i have a running dvb-t device

[sepius]

Thanks ppsalama, this process worked for me perfectly on a Linux Mint (Katya) amd64 architecture.

Muchas gracias.
