SASC-NG with Ubuntu 11.10 3x Kernel

[dcdc123]

Hi,

I'm trying to get sasc-ng workng ubuntu 11.10 (mythbuntu 11.10 more specifically). I have been following these tutorials:
http://dolot.kipdola.com/wiki/Install_S ... pendencies
http://dolot.kipdola.com/wiki/Compile_Linux

Once I get to "modprobe dvbloopback" it tells me its an 'invalid argument'. I'm pretty stuck on this can anyone offer any tips?

cheers

If you run "modprobe dvbloopback" is because all compiled well...
Did you tray "modprobe dvbloopback num_adapters=x"? where x is number of adapters installed

Other question. Can you read italian? http://forum.ubuntu-it.org/index.php/to ... 152.0.html there is an instalation on kernel 3.0, but be carefull because it aply a patch in a file that is in tbs driver too and I don't know if it a good idea.
If you try anyway, you need aply the patch to tbs driver and not to vanilla kernel as it indicated in this page.

Best regards.

When I try that it gives me the same "Invalid Argument" repsonse. I guess I havent compiled everything correctly.

My Italian is a bit limited but i guess i can use google translate to a certain extent. Have you been sucessful in getting sasc-ng to work n ubuntu 11.10?

Thanks v.much

Where say:

Code: Select All Code

cd /usr/src/linux-[VERSIONE_SCARICATA]
wget http://www.vanbest.org/drupal6/sites/www.vanbest.org/files/linux-2.6.38-dvb-mutex.patch
patch -p1 < linux-2.6.38-dvb-mutex.patch

There is appling the patch, but you need to chage to directory where you have tbs drivers before run wget.
For exjample, I allways download tbs drivers to /usr/src/tbsdrivers and unzip there. Then:

Code: Select All Code

cd /usr/src/tbsdrivers/linux-tbs-drivers

Best regards.

Thanks!

I have followed the whole thing through and when i write 'ls /dev/dvb' it says adapter0 ( i should have at least 10 adapters )

I have just tried doing what you said and it tells me that there is no such file or directory 'skip this patch?' what can i do?

[SergioDanielG]

Sorry. The patch it maked to replace vanilla kernerl.
Can you edit it?
Change the first line

Code: Select All Code

diff -Nur linux-2.6.38/drivers/media/dvb/dvb-core/dvbdev.c linux-2.6.38/drivers/media/dvb/dvb-core/dvbdev.c

To

Code: Select All Code

diff -Nur linux/drivers/media/dvb/dvb-core/dvbdev.c linux/drivers/media/dvb/dvb-core/dvbdev.c

Best regards.

[dcdc123]

sorry where do i enter that?

ive just tried removing and reinstalling the kernels as my tuners werent working and i couldnt re-install. Can i still edit or do i have to do the whole process again? :S

[SergioDanielG]

You need to modify downloaded patch file.
In a console, change to directory where you download the patch en edit it with nano

Code: Select All Code

nano linux-2.6.38-dvb-mutex.patch

There replace the first line

Code: Select All Code

    diff -Nur linux-2.6.38/drivers/media/dvb/dvb-core/dvbdev.c linux-2.6.38/drivers/media/dvb/dvb-core/dvbdev.c

to

Code: Select All Code

    diff -Nur linux/drivers/media/dvb/dvb-core/dvbdev.c linux/drivers/media/dvb/dvb-core/dvbdev.c

<ctrl>+<o> to save
<ctrl>+<w> to exit

Be carefull, there are 2 patch to aply in tbs drivers (the second in DRIVER DVB/V4L)
Then recompile tbs drivers and continue to SASC-NG section.

Best regards.

[dcdc123]

Sorry not sure where you mean in regards to the 2nd patch.

Do you mean run the patch file in the following folders?:

tbsdriver/linux-tbs-drivers/ (just tried this after editing first line and i get the same result as before - 'can't find file to patch at input line 4')

and

tbsdriver/linux-tbs-drivers/v4l
