Make failed - standard ubuntu 9.10

Please can someone assist, not sure what the cause of the below is? This is my second attempt to get linux tv to work, I suspect it's a basic level error - sorry I'm fairly new to Linux... output below, I'm running a fairly standard ubuntu 9.10 setup.

make[1]: Entering directory `/home/david/v4l-dvb/v4l'

I think you don't have the kernel development files installed.

The recommended reading would be:
http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

Thanks, I've been trying to follow the wiki, but getting this error. The main kernel packages seem to all be installed, but perhaps something less obvious is missing - hard to tell without a definitive list of dependencies. Help would be much appreciated!

Its looking for .config file inside the kernel source.

/lib/modules/2.6.31-17-generic/build/.config
1) check that /build is a symlink to /usr/src/kernel-path-source
2) IF there is something like /proc/config , copy it to
/usr/src/kernel-path-source/.config
IF NOT, then you could try doing a make oldconfig ....

I really dont know that the ubuntu packages includes inside, so, those are my 2 cents...

2010/1/29 David Henig <[email protected]>:

Thanks, eventually tip 1 fixed this. For some reason I had 2.6.31-17-generic without a .config, as I seem to be using 2.6.31-17-generic-pae. Creating a symlink to that fixed this error.

Unfortunately still can't finish build, I get an error in firedtv-1394, as shown below. Do I need to reinstall, as I also get the following message?

***WARNING:*** You do not have the full kernel sources installed. This does not prevent you from building the v4l-dvb tree if you have the kernel headers, but the full kernel source may be required in order to use make menuconfig / xconfig / qconfig.

If you are experiencing problems building the v4l-dvb tree, please try building against a vanilla kernel before reporting a bug.

Thanks again for any help, I'm sorry I'm only a couple of months into linux, I'm just trying to do this against what I thought was a fairly standard build...

Hi David,

It looks like you don't have the kernel headers package installed. In Ubuntu this package is called linux-headers-generic for the generic kernel, and linux-headers-server for the server kernel, etc and so forth.

If you have this package you shouldn't need to any symlinking with the .config, either. I didn't have to.

Regards,
Frank.

Thanks, I appear to have the headers and no longer have to do the symlink, but still getting the same error - any help gratefully received, or do I need to get a vanilla kernel?

Open up the file v4l/.config and change the line for firedtv from "=m" to "=n". Then run "make".

This is a known packaging bug in Ubuntu's kernel headers.

Thanks, this is sounding promising, only thing is I'm not seeing a .config in the v4l directory although it shows up with the locate command, am I missing something very obvious.

David

Sorry if I'm telling evidence, but just a hint: every file starts with . is a "hidden" file. So you'll need something like ls -a lib/modules/2.6.31-17-generic/build/.config , see "man ls".

This issue is specific to Ubuntu. With Fedora and with upstream kernels, everything compiles fine.

Maybe the better is if one of you that use Ubuntu to write a patch checking for the affected Ubuntu versions, and automatically disabling the compilation of this module, or doing some changes on compat.h to properly compile it.

All it is needed is to patch one of some of those files:
v4l/scripts/make_kconfig.pl (for the logic to disable it on Ubuntu)
/v4l/compat.h (if is there some compat stuff that can be added)
/v4l/scripts/make_config_compat.pl (for a most sophisticated logic based on some script)

After having the patch done, just submit it to Douglas.

Cheers,
