Uhmmm, writing a kernel module is the last thing you should be doing as a beginner. If you’re just compiling one, then it depends heavily on the module you are compiling, and the documentation from that module writer is what you should go by. If they don’t have good instructions on how to compile and install, I’d be super hesitant to use it.

Overall, I thought this was super helpful. I almost had to stop and make the sample module and load it just to do it :)

Very useful material

Thanks for the post. I have to compile a module on my VPS that run centOS 32 bit. The folder /lib/modules/ is empty. I looked for the build file on /usr/src/ and other folders on server without luck.

Could you please shed some light on this..?

Wget fluctuates from as high as 790 kb/s to as low as 50 kb/s, and every number in between.

The only real flaw with Axel is an easy fix but one that should be made default. The actual terminal output. There is an alternative output that keeps your download progress to a single line, but someone new probably wont find it.

I am getting the same error using Ubuntu version 2.6.24-19-generic. Did you get to the bottom of this? I am pulling my hair out!!

What if, in the end, your brain is the only thing standing between you and utter failure?

Would you then quit and blame the world for your problems?
Or would you actually think and maybe think hard and long but keep thinking and trying until you come up with a solution?

And if in the end, you do that, why would people not say “well it would be nice if you would just do that normally”?

I’m not saying that that’s the right attitude especially in a help file.
But if the difference between self-sufficiency and helplessness is 5 minutes of thought?
Do you really want to make a habit of taking 30 seconds to type a question vs 5 minutes to think through all the options on your own?

Anyway having seen this thread two dozen times long after I finished with it I would still have to look at my original posts and say that the answer was not found solely in this example. I had to pull up many pages on the same topic and try to get the examples to work there..and when I did so I found out many things which helped me to get this to work. This was definitely not the answer all on its own.

Yes, Linux sucks that way. It’s definitely true.

But it can be done and thus the bar exists between the self-sufficient and the overly-dependent who hire them and pay them to do IT work.
That’s just how it is.
And were it not that way, Linux software would probably not be open nor would it be so advanced. You’d probably still have software repositories with freeware and shareware but it would be the same crap that you can get for Windows. Instead of having a multitude of development in Linux that is eventually ported over to Win32/64 and made available for free, you’d get a bunch of time-limited shareware crap that is just a copyright-infringement on some expensive proprietary package and very little if any real development would happen in the user-space. We’d be stuck in 1995 and MS would still rule the PC market.

It is that very arrogance and standoffishness that has helped to free MS users from their chains.
Without it there would be no competition and no real freedom of choice in the mainstream market.
And you can’t have your cake and eat it at the same time.
Face it: the guys who really know their shit are far too busy to help newbies who can’t be bothered to take the time and make the effort to think on their own, not to mention who lack the intellect to do so effectively.
And for very good reason. They are too smart to let themselves get dumbed down to the point of ineffectiveness.

And if you think that it is bad here, try going to college and asking your professors stupid questions and see how well that works. No one owes you any explanation for anything and they certainly are not going to waste their time and energy giving you an endless series of explanations. Indeed many people will happily say nothing and let you suffer, just for the entertainment-value that you present to them. Of course you may not like that, you may even resent that, but believe me they probably don’t like you and certainly resent you as well. They will definitely resent doing your thinking for you and having you benefit as a result instead of them.

And there are a lot of people in this world who walk around expecting people to help them regardless of how stupid or lazy they are. That’s just not a good way to go through life. Eventually someone will make you pay for it. And pay badly…pay in ways that you have yet to even imagine. And then blame you for being stupid enough to get in that position when the real fact is that they merely took advantage of you. That’s not really going to help you when you are the one lying there curled up in pain, even more helpless than before, and they are walking away laughing and counting your money.

The key to happiness in life is self-sufficiency not a support-network.

thanks so much!

$(PWD) should be $(shell pwd)

Since PWD is not defined, I think it attempts to compile the entire kernel source.
It solved this error I got:
“make[2]: *** No rule to make target `kernel/bounds.c’, needed by `kernel/bounds.s’. Stop.”

Thank you for the examples and explanations.

I had a particular question and wanted to ask here- I did try and google for my answer in various ways, but I did not find any clear answers.

I have an embedded linux device running 2.6.28 on ARMv6-compatible processor rev 6 (v6l).

I don’t have access to the kernel, but the ntfs.ko is being loaded as a module and is in a directory where I can alter it.

The ntfs.ko loaded for the device does not permit read/write access- just read only.

The device does not have any package loaders, (no apt-get).

I have an ubunutu install and could run commands from there (though your article seems to imply you would be working with the headers on the actual/running kernel) or is it possible for me to get/install the headers on the embedded machine without apt-get?

Anyway, thanks for your hard work,
embedded_user

Linux is not exactly the most straightforward, logical, and debugged OS that there is out there. But people like you who write first and then think second (if ever, and certainly not well) just make the situation worse. Maybe it hasn’t occurred to you yet but people who know what they are doing don’t want to help people like that because they don’t want to deal with them. You can’t expect someone to help you with every fucking question that you might have about anything they say, no matter how stupid your question is or how easily it would be answered if you would just use either your brain or Google not to mention both. People do not exist to help nitwits like you stumble through life.
