Unable to compile driver for kernel 3.7.0-7

[knaj]

Hi. I was just wondering if anybody else is experiencing problems with this kernel? I'm running ubuntu 64-bit and 3.5.0-18 & 27 compiles fine and everything works, but the latest one refuses to work. If I try to compile it booting from the 3.7 kernel I get errors while compiling "WARNING: could not find /home/knaj/tbs130318/linux-tbs-drivers/v4l/.tbs6991fe_driver.o.cmd for /home/knaj/tbs130318/linux-tbs-drivers/v4l/tbs6991fe_driver.o". I tried booting from 3.5 and compile for 3.7, and that compiles without error but the modules refuse load. dmesg gives the following errors and tvheadend crashes. Am i missing something?
cx2341x: disagrees about version of symbol v4l2_ctrl_grab
cx2341x: Unknown symbol v4l2_ctrl_grab (err -22)

When I compiled for another kernel version i just did a make release VER=3.7.0-7-generic

Any help is appreciated. Unfortunately I can't revert back to 3.5 kernels because a graphics bug causes XBMC to hang after a while. With 3.7 it's rock solid, except that I can't watch tv

uname -a
3.7.0-7-generic #15-Ubuntu SMP 64-bit

If you switch to a new kernel you have to do a make distclean first then recompile.

make sure your /usr/src/linux sym link is pointing to the kernel youve booted into.

Hi. Thanx for the quick reply.. I did a make distclean before compiling. I've compiled these drivers many times before and it's only with this kernel I'm having problems.. I'm not shure what you mean with /usr/src/linux.. I don't seem to have that symlink..

Sorry, the above output was lsl /usr/src/linux-headers-3.7.0-7-generic/
And content of /usr/src

cd /usr/src
sudo ln -s linux-headers-3.7.0-7 linux

Ive often had issues with the linux-headers pkg not containing all the headers, so I like to use source. its alot bigger, but has everything in it.

sudo apt-get install linux-source
cd /usr/src
sudo rm linux
sudo ln -s linux-source-3.7.0-7 linux

After the make clean did you rerun the v4l/tbs-x86_64.sh or v4l/tbs-x86.sh script ?

I've tried what you suggested, and the new 130429 drivers but the problem remains. Now I the only warning I get when I compile is

Code: Select All Code

WARNING: could not find /home/knaj/tbs130429/linux-tbs-drivers/v4l/.tbs6981fe_driver.o.cmd for /home/knaj/tbs130429/linux-tbs-drivers/v4l/tbs6981fe_driver.o

. Is it possible to build the drivers if I boot from a 3.5 kernel with just make release VER=3.7.0-7-generic? Do I need to do anything else?

[knaj]

Forgot to answer your question, yes i reran tbs-x86_64 after make clean.

[updatelee]

That's just a warning because the module is pre compiled.

sudo make install

And reboot

[knaj]

No luck. The module refuse to load with 3.7.
My patience has run out and I'm reverting back to a separate computer running 3.5 with the DVB-card. Thanks anyways for helping me!

for what it's worth; same issue here.
3.7.10-1.1 (opensuse 12.3)

glad to see i'm not the only person having issues so i'll need to find another kernel somehow!!
