Hey

I think this mail came not through, so I send it again. Sorry, when it comes twice.

I just pasted the interesting things into this email (With some comments inline). Hope somebody can help:

to get the newest v4l source.

make menuconfig in ~/Projects/webcams/v4l-dvb and remove all stuff except the gspca and V4l2.
After this, I did not find a .config file in the ~/Projects/webcams/v4l-dvb folder. Where is the .config stored? Several dvb and/or analog capture driver where made. Why?, I disabled!

Hope anybody can help me.

Please try make rmmod before plugging-in your device and check that no v4l-dvb module is loaded.

When I did "make menuconfig" I only choose the v4l2 and gspca modules. But looking in .config in ...../v4l/ there are still some more modules enabled. I can manually remove them from the .config file, but that should not be the way to go, or I am mistaken?

I did several "sudo modprobe -r gspca-...." and check afterward that no gspca module is loaded anymore (lsmod |grep gspca).

You may copy the /boot/config to <hg root>/vl4/ and do a make menuconfig (but this will not work without the kernel sources).

This is the old driver gspca v1. If it is still present in /lib/modules/... , remove it.

I think these old modules are loaded at system startup time from initrd. You should rebuild this one.

Cheers.

Hello Jean-Francois

Thanks for you comments. More from me inline.

I did, but shouldn't it be possible to just download the the v4l-dvb source and compile and install without fiddling around with the distribution's config file?

I could compile everything just with the kernel-headers. The complete kernel source was not required.

Now some logs after copy the config-2.6.24-21-generic to v4l/.config and do a new compile and install. I rebooted after this was done:

thomas@LAPI01:~$

Looks like the correct modules are loaded but I still have the "Unknown symbol" problem.

At these times as I was contributing to the gspcaV1 project, I never had such kind of problems.

I have to stress this one more: It should be possible to _just_ compile the source downloaded from linuxtv.org!

I got some time and I would like to test the new gspca V2 v4l2 driver but with this issues I will get up soon :-(

I have about 20 webcams laying around which I would like to test with the new gspca V2 "in kernel" drive with a "stock distribution (Ubuntu)" kernel.

Sorry, I am a bit frustrated right now. Even I am frustrated, Jean-Francois, you did a great job. Hans with his v4l_lib, too :-)

Regards, Thomas

Hey

I think this mail came not through, so I send it again. Sorry, when it comes twice.

I just pasted the interesting things into this email (With some comments inline). Hope somebody can help:

After this, I did not find a .config file in the ~/Projects/webcams/v4l-dvb folder. Where is the .config stored?

OK, I found it, thanks.

Look at the .config, perhaps you forgot to disable some additional modules

When I did "make menuconfig" I only choose the v4l2 and gspca modules. But looking in .config in ...../v4l/ there are still some more modules enabled. I can manually remove them from the .config file, but that should not be the way to go, or I am mistaken?

Well, if you disable all options, you will see that no module are compiled.
If you enable just 1 gspca webcam or whatever module, some modules like tuners are compiled by default.
Some options need to be checked in order to able to remove some modules.
For example the option "Customize analog and hybrid tuner modules to build" must be checked to see the list of tuners, and to allow you to disable them one by one.

Please try make rmmod before plugging-in your device and check that no v4l-dvb module is loaded.
This will remove any old v4l-dvb module already present.

I did several "sudo modprobe -r gspca-...." and check afterward that no gspca module is loaded anymore (lsmod |grep gspca).

Well, the problem is the kernel version taken from the build script is different from the running kernel.
It is a very common problem on debian/ubuntu distributions that add some extra version information in kernel version but not in /usr/src/linux/Makefile There may be a clean method to build modules with these distributions, you might look for that on corresponding ML.
To see the problem, do a modinfo gspca and a modinfo video_ioctl2 or a modinfo videodev and compare the vermagic.
Hope that this will help you in finding the solution.

Thierry

Hello Jean-Francois

I got some time and I would like to test the new gspca V2 v4l2 driver but with this issues I will get up soon :-(

I have about 20 webcams laying around which I would like to test with the new gspca V2 "in kernel" drive with a "stock distribution (Ubuntu)" kernel.

Please don't give up we would really like to have you onboard, you did a greta job with the gspcav1 pixart drivers and I'm sure you will make a valuable contributor!

The problem is that gspca now is part of the v4l-dvb tree, so when you build it now you rebuild the entire v4l subsystem really, this means that you must make sure that all v4l modules, including videodev.ko are unloaded before trying to modprobe for example gspca_pac207, so that the new version of videodev.ko gets loaded.

This has been working fine for me both with older and newer kernels (on Fedora), so if you are really sure no old modules are loaded, it might be there is something funny / weird going on with the way your distribution provides kernel sources for building out of tree modules (as Thierry hints at).

To give you an idea, here is how I test gspca:

--- begin test.sh ---
#!/bin/bash

set -e

make
sudo make install

sudo rmmod gspca_sonixb || :
sudo rmmod gspca_spca501 || :

Hello Hans

I didn't gave up, yet ;-)

Recently, there was a kernel upgrade for Ubuntu. I updated and built the v4l-dvb tree new, without doing a "make install". After that I insmoded the needed modules (videodev, gspac_main, gspca_....) by hand and the cam worked :-)

After that I check the kernel log and found "Unknown symbol" from gspca again! But now I recognized that these errors are coming from the old gspca module which ubuntu tried to load as I plugged the cam.

I blacklist the gspca module, did a "make install", rebooted, plugged the cam and it was working with the new gspca module. No "Unknown symbol" messages anymore in the kernel log :-)

But I still don't know why it did not work before. Anyway I am happy at the moment :-)

Thomas
