v4l-dvb asking for kernel that is not there
 
I'm trying to install the v4l-dvb package from here on fedora 20 64bit. I got the git clone ok and ran make, it took ages but it did complete, but when I ran make install I got this error:
Code:
sh ./arch/x86/boot/install.sh 3.15.0+ arch/x86/boot/bzImage \
        System.map "/boot"
depmod: ERROR: could not open directory /lib/modules/3.15.0+: No such file or directory
depmod: FATAL: could not search modules: No such file or directory
Kernel version 3.15.0+ has no module directory /lib/modules/3.15.0+
why is it looking for this kernel? there is no 3.15.0 kernel on this machine. I have
Code:
# uname -r
3.14.8-200.fc20.x86_64
and that was after doing yum update and rebooting. I've been searching on google about this but can't find anything, how do I get make install to recognise my kernel and run properly?

Perhaps it is related to the command
Code:
sh ./arch/x86/boot/install.sh 3.15.0+ arch/x86/boot/bzImage \
        System.map "/boot"
Is the 3.15 in this command related to it looking for the 3.15 kernel? If you changed the "3.15.0+" to "3.14.0+" would it then be looking for a 3.14 kernel?

the file /arch/x86/boot/install.sh does not contain any reference to 3.15.0
the file arch/x86/boot/bzImage did contain a reference to 3.15.0 which I edited to 3.14.0
the file /boot/System.map does not contain any reference to 3.15.0
however after doing this one edit the make install command is still giving:
Code:
# make install
sh ./arch/x86/boot/install.sh 3.15.0+ arch/x86/boot/bzImage \
        System.map "/boot"
depmod: ERROR: could not open directory /lib/modules/3.15.0+: No such file or directory
depmod: FATAL: could not search modules: No such file or directory
Kernel version 3.15.0+ has no module directory /lib/modules/3.15.0+
I still don't know why this is looking for a kernel that's not there.

Whatever editing you did (any reason for not telling us what you did?) clearly had no effect on the the line
Code:
sh ./arch/x86/boot/install.sh 3.15.0+ arch/x86/boot/bzImage \
        System.map "/boot"
My guess is that you have to find the source of that line and modify it accordingly. If you modified the file arch/x86/boot/bzImage and it had no effect then it is clearly not the source of the 3.15.0+ in the faulty line. I don't run Fedora so I really can't help you any more than that.

I assume you have installed the correct kernel headers file (3.14). Is that right?

hi yes I have all the dep's installed.
The edit I did before was: opened arch/x86/boot/bzImage, searched for '3.15.0', found one instance of it and I changed it to 3.14.0 and saved the file.
I did a search on the term '3.15.0' in the v4l source folder and it found literally hundreds of files containing this term. so from here I don't know how to find the source of the line in question. It could be any one of hundreds of files.

Does that mean that you have installed the linux headers for your kernel? I think it's called the "kernel development package" in Fedora-speak.

But from the procedure you're using, it sounds like you're trying to compile v4l-dvb from source rather than using the already compiled package, is that correct? If so, why not just install the package rather than compiling from source.

there are no linux headers for fedora, there are however 'kernel-headers', which are installed along with kernel-devel.
Yes I am trying to compile from source.
'the already compiled package'? I haven't come across that. Have you seen such a thing and if so, can you provide a link?

Sorry. It was your reference to a package that fooled me.

I haven't heard of any precompiled packagage for v4l-dvb
