Makefile confused about kernel version that's running - Failed Module Insertion

Well, you have to set this CFLAGS in your environment for it to work, try putting it in front.

Code:

CFLAGS="-march=i486" your command here

Or maybe there are already other CFLAGS set, then this should work.

Code:

CFLAGS="${CFLAGS} -march=i486" your command here

And what did you mean by 'dmesg -W' not working? You were supposed to run it in one terminal, leave it running and then try module insertion in another terminal. Is that what you did?

NB! Grepping logs is sometimes misleading, there may be other interesting lines before and after your grepped line.

Hi, sorry I didn't understand the usage of your dmesg -W idea, however, when I type dmesg -W I get an error that -W is not a valid option ??

So i just typed dmesg before and after executing ./make_all CFLAGS=..... KERNELDIR=.....

Attached screenshots of dmesg output before, and after running ./make_all.

Unfortunately this still didn't work.

I also tried installing this driver on LinuxMint (2.6.32.21), which DOES properly recognize both CPU cores of the Vortex, but, the driver still failed to install, although the behaviour was a bit different.

Here's the Linux Mint behaviour, see images attached.

I see your module still builds for i686. You probably need to run configure with CFLAGS also. Maybe you should run

Code:

export CFLAGS="-march=i486"

before you start with configure. I'm not a coder, perhaps someone with coding experience chimes in and tells how to do it properly.

Edit: copy-paste from terminal window is so easy in Linux, taking screenshots is much harder and they are harder to read than plain text. Why pictures?

Edit 2: See here, this is how you post smaller logs

Thanks for the tip re: copy and paste, I'll try that next time !

I tried to find a good copy-paste tutorial from Youtube but found none where it is done the easy way! Basically you hold down the left mouse button, mark the text you want to copy with mouse, and then use middle click here on forums to paste it. Done in 2 seconds. Although I'm not 100% sure it works like this in your rather ancient version of Linux, even 'dmesg -W' did not work.

You don't have a v 2.6 module, but something MUCH newer.

Linux 2.6 was released in 2014.

I think you will need kernel version 2.6.21 at a minumum, but not sure.

Your system really needs to be updated...

One of the things that can prevent a kernel from being inserted is if the kernel version in the module doesn't match the running kernel.
