uname vs real arch linux system

Hi,

I just installed arch and trying to compile something. I get this error:

$ make
make -C /lib/modules/3.14.29-1-lts/build M=/home/emre/homeworks/hw2/part1 modules
make[1]: *** /lib/modules/3.14.29-1-lts/build: No such file or directory.  Stop.
Makefile:3: recipe for target 'all' failed
make: *** [all] Error 2

I tried the following:

'$ uname -r'  command gives me: '3.14.29-1-lts' but my actual module is in '3.14.32-1-lts'

so I guess my uname is wrong? How can I change it? or Is my system broken?

Thank you for help!

Best

Re: uname vs real arch linux system

I suspect you simply haven't rebooted since your last kernel upgrade.  The modules installed match the kernel installed, but uname reports the currently running kernel.

Stop.

What is the output of pacman -Qi linux   ?
It might be you have not rebooted since you updated your kernel.  It might also be that your boot partition had not been mounted when you last updated your kernel.

Re: uname vs real arch linux system

yes, I don't think I have rebooted:

$ pacman -Qi linux 
Name           : linux
Version        : 3.18.6-1
Description    : The Linux kernel and modules
Architecture   : i686
URL            : http://www.kernel.org/
Licenses       : GPL2
Groups         : base
Provides       : kernel26=3.18.6

it gives me a whole different version though. I have installed yaourt and been playing with that. I wonder if that has something to do with this?

Re: uname vs real arch linux system

Okay, do reboot.   Then let's compare the versions returned by uname -a and by pacman -Qi linux
Once those agree, we can worry about the correct way to build modules.   (Hint, let's try to not use make by hand).

BTW, can you post your /etc/fstab file?

Re: uname vs real arch linux system

He seems to be using the linux-lts kernel. So, he should instead use the command pacman -Qi linux-lts.

Good catch  -- Thanks.

If you have updated your system with yaourt then yes.

You can compare the last boot time to the installation time of the kernel with the following commands (use "linux" instead of "linux-lts" if you're using the normal kernel):

last -x | sed -n '/boot/{p;q;}'
pacman -Qi linux-lts | grep 'Install Date'

Re: uname vs real arch linux system

I use 'uptime -s' instead of last + sed.
