Installing Kernel Source
 

First of all, i'm tying to install this:
http://www.tanzband-scream.at/line6/index.html

I've downloaded the Binary version for the RPM installation, and extracted it. As the instructions say, i need to type "rpmbuild -tb line6usb-0.7.3.tar.bz2" first.

However when i do that i get this:


mark@mark-desktop:~$ sudo rpmbuild -tb line6usb-0.7.3.tar.bz2
error: Failed build dependencies:
kernel-source is needed by line6usb-0.7.3-1.x86_64


I've looked on google for installing the kernel source for Ubuntu, and from what i've managed to do so far appears that i have infact downloaded the kernel source, to test it again i type this in Terminal:


mark@mark-desktop:~$ sudo apt-get install linux-source
Reading package lists... Done
Building dependency tree
Reading state information... Done
linux-source is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
mark@mark-desktop:~$


In my /usr/src folder, there is "linux-source-2.6.24.tar". From a tutorial i extracted that, and have a folder called "linux-source-2.6.24" that contains alot of stuff.

Why am i getting the error that i need to install the kernel source, when it seems to be already installed? I have the kernel headers installed also, i think they were already there when i installed Ubuntu.

uname -r gives out "2.6.24-21-generic" and im using the 64bit Ubuntu 8.04, if that helps.

It's looking for a package named kernel-source. It doesn't matter that you've got the source code for the kernel installed. As long as you don't have the kernel-source package installed, you'll keep getting that error.

You may need to create a link called "linux" (in the same /usr/src directory) that points to the linux-source directory.

Thanks.

I tried this:

mark@mark-desktop:~$ cd /usr/src
mark@mark-desktop:/usr/src$ sudo ln -s /usr/src/linux-source-2.6.24 /usr/src/linux

And i still get the same error.

i then tried this:
mark@mark-desktop:/usr/src$ sudo ln -s /usr/src/linux-source-2.6.24 /usr/src/kernel-source

And it still gave me the error.

I'm really confused at the moment!

Try this, it is what I used:
http://www.howtoforge.com/kernel_compilation_ubuntu

I might be wrong here but it certainly won't do any harm!!

yum install kernel-devel kernel-headers

then have another go at building rpm

So you are running the 2.6.24-21-generic kernel. This is a 32-bit kernel. You may have 64-bit hardware, but you are running a 32-bit kernel. This is perfectly OK.

But you have installed linux-source-2.6.24
This is different from 2.6.24-21-generic
So your kernel source does not match the running kernel. So things will not work.

Install the headers for your currently running kernel like this
You might also have to
to install the c compiler and other utilities required before you can compile from source.

Then try again

@james.farrow:
kernel-devel and kernel-headers are not the names of ubuntu packages, and ubuntu doesn't use yum, so this will not work.

This is interesting. I'm sure i tried to do that, and it didn't find that kernel, maybe i was going it wrong however. I'll try again :)

I;ve discovered what i'm installing does not work with the 2.6.24-xx kernel, and found a way to install the Ubuntu 8.10 Kernels (2.6.27), and i managed to compile the source with make install instead of the other way. The source would not compile properly with 2.6.24-xx, hency why i was doing the RPM installation. I'm not entirely sure if it worked. I've managed to mess up my xorg.conf file and i don't get as far as a GUI.

I think i might just download Ubuntu 8.10 and start fresh. I know its only beta at current, but it should be alright.

As for the 32-bit kernel, i'm not sure how that happened, as i downloaded the AMD64 version of Ubuntu. Maybe this just ships with a 32-bit kernel? And your correct, i do have 64-bit hardware (AMD64) :)
