I don't understand why my kernel compile is failing...?

[pastored]

Hello, everyone. Thanks for reading this post.

 

I'm trying to recompile my kernel, as per the tutorial mentioned in the FAQ. However, I get to a certain point, and this is the error message I get:

 

structure has no member named `users'

 

(it's for a videodev module - I'm trying to enable video capturing in Linux)

 

Help! I REALLY don't want to go back to Windoze just to capture video!!

 

Any help would be greatly appreciated.

It would be more helpful if you would be more specific about which point is 'a certain point', please. Maybe post a couple lines before and after. I'm assuming it's during 'make modules', but it would still be helpful to see some of the actual output.

When do you get the error?...make modules?

Can you post about 20 lines from the error and up?

 

Did you change any of the defaults in the....-forgot what it's called- video 4 linux Section? (Y,M)

[pastored]

Thanks again for all your help, guys.

 

By the way, I'm following the tutorial at

 

http://www.mandrakeusers.org/viewtopic.php?t=4595

 

and I'm using this page for some pointers

 

http://www.reades.com/radeon.html

 

Anyway, when I

 

make dep bzImage

 

I see this:

So, what does that MEAN? I'm way lost here...

[beesea]

i don't know if this'll make a difference, but i compile my kernels with:

make dep && make clean bzImage modules modules_install

maybe you need to run make clean first? i dunno, i'm just spitting out ideas here....

[bvc]

You are correct! At least on Mandrake kernels. Doing 'make clean' didn't sit well with LFS.

 

I do;

make mrproper

make xconfig

make dep clean bzImage && make -j5 modules && make modules_install

 

and so on.

 

I'll pm aru about the FAQ. :wink:

[pastored]

I tried

 

make dep clean bzImage && make -j5 modules && make modules_install

 

and I still got the exact same errors.

 

Next idea?

[aru]

hehe, I was pretty sure of that (bvc, check the PM I sent you) :mrgreen: ;)

 

 

I don't think there is anything wrong with the FAQ you are following (I've edited it this morning to clarify things a bit more anyhow). I think that the problem is with your kernel configuration.

 

When you configured your kernel, did you read the help when you enabled those video features? Probably you missed to enable something else needed for the feature you are trying to compile.

 

HTH

[Steve Scrimpshire]

That's what I thought initially, too, aru, but I've looked at Video 4 Linux in the make xconfig and the help doesn't say anything about needing to enable anything else as far as I could see.

[bvc]

Also try to keep it simple. For the video section, try to keep a consistency btween what's in the kernel and what's a module. Either make them modules (best way) or put them in the kernel....not both.

 

On the clean thing......like I told aru, it's how I've always done it based on intructions on the internet for mdk kernels. It's always worked for me and as aru pointed out may not actually be doing anything :roll: but I always figured it was cleaning up after make xconfig and dep b4 running bzImage.

 

Is it happening at make dep?...or make bzImage? The first thing I do when having probs is run them individually instead of together, so it's easier to pinpoint the prob. You may not even be getting to make clean yet :shock: :wink:

[aru]

Also try to keep it simple. For the video section, try to keep a consistency btween what's in the kernel and what's a module. Either make them modules (best way) or put them in the kernel....not both.

I agree with you in that point.

 

 

Is it happening at make dep?...or make bzImage?

It is probably happening at make bzImage as per how the output looks like.

 

I think you should compile all that stuff as modules.

[aru]

In the Makefile I've found a rule named checkconfig, I'm wondering if running that one after editing the configuration would show misconfiguration failures.

 

make checkconfig --> runs the script "/usr/src/linux/scripts/checkconfig.pl"

 

Another promising one is:

 

make checkincludes --> runs "[..]/scripts/checkincludes.pl"

 

 

I 've never tried them, and I'm too lazy and tired now to check if those things work or not :P

[pastored]

Whoo Hoo!

 

Of course, I cheated. I completely reinstalled Mandrake 9.1, and so I was able to start with a fresh installation.

 

I think my PROBLEM was that I had tried to add some extra module to get my video capture to work... but when I tried the recompile with a "pure" source, it worked like a charm.

 

I am now posting from a newly "Duronized" kernel. MUCH faster. :D

 

Now if I can just figure out how to "duronize" my other apps... :D

 

Thanks for your help guys!
