Kernel Source There But Not There

JyushinX · 08-05-2005, 06:31 PM

Hi,

So I'm trying to install Nvidia's latest Nforce drivers on Linux Mandriva LE2005 x86_64. I get an error message stating that it cannot find the path to the kernel source. So I take a look in /usr/src. There is no linux directory, just one called RPM. When I navigate into this RPM directory and attempt to run the kernel-source rpm, I get the message that it is already installed. But if it's not in /usr/src, then where is it?

Thanks.

Have you tried

updatedb
locate linux

Am I supposed to enter those at the command prompt?

Because if so, both updatedb and locate linux return "command not found".

Yes, at the command prompt.

You may have slocate and slocate.updatedb (or slocate -u) - you can always search for such tools in the directories /usr/bin and /usr/sbin (and very rarely can they be in /sbin).

You can always try, e.g. "man slocate" to see if they're installed on your system. Usually if the tools aren't there, the manpage won't be. Your distro may also have a way of searching for files in your installed packages. In the jargon, you want to know what "owns" the file. Most distros also allow searching for files that aren't installed; that will tell you what package you need.

locate is basically making "find" faster. Ordinarily, you could get the same results by doing a

find / | grep file_you_want

but that looks at every file in its physical location every time you run it (well, depending on what filesystem you use, but that's a technical point). locate or slocate, instead, search a database that you can create with updatedb. This means you do a full "find /" only when you create the database - all subsequent searches are much, much faster - usually instantaneous.

Well you can use rpm to look for the files of an installed package, just type "rpm -qa|grep kernel", look at the name of the kernel-sources package(let call it foo) and then type "rpm -ql foo" and it will display all the files of tha package,and of course its path. Locate, find and all that commands are valid too of course!!
