Hi,

I am having problems building the drivers (linux-tbs-drivers_111013.zip) on a 3.0.4 kernel.
firmware gets loaded:

cx24116_firmware_ondemand: Waiting for firmware upload (dvb-fe-cx24116.fw)...
cx24116_firmware_ondemand: Waiting for firmware upload(2)...
cx24116_load_firmware: FW version 1.23.86.1
cx24116_firmware_ondemand: Firmware upload complete

...but I have no module

snowball:/usr/local/src/TBS# lsmod |grep cx23885
snowball:/usr/local/src/TBS#

...nor has it been installed

snowball:/usr/local/src/TBS# find /lib/modules/3.0.4/ -name cx23885*
snowball:/usr/local/src/TBS#

When I look at the building process it self, I do get a Warning
(and yes, I ran the script to tell the config that it's the 64bit version I want)

and looking in the directories, no kernel module has been build either...

Any tips?

Downgraded to 3.0.0, same results...

and no luck with the just released kernel 3.1.0...

Solved it!

For future reference:
When you have run make for the first time, it will create a custom configuration file named .myconfig under the v4l directory
(linux-tbs-drivers/v4l/.myconfig)

Edit .myconfig and search for CX2388, you will find a row that looks like this:

Code: Select All Code: CONFIG_VIDEO_CX23885 := n

the n says that NO module should be compiled. Change that n to an m and a module will be created

Code: Select All Code: CONFIG_VIDEO_CX23885 := m

re-run make and do the make install, and you're all set! (modprobe cx2388x if you want to try your module right away)
