build problem because of a broken link

[johnb]

I'm getting this error trying to build a driver for my nic card...

[root@localhost Linux]# make
#@make -C /lib/modules/2.6.18-53.1.14.el5xen/build M=/root/Linux modules
make: *** /lib/modules/2.6.18-53.1.14.el5xen/build: No such file or directory. Stop.
make: *** [modules] Error 2

When I go to..

I get...

lrwxrwxrwx 1 root root 54 Mar 17 09:59 build -> ../../../usr/src/kernels/2.6.18-53.1.14.el5-xen-x86_64

all in red... which means a broken "ln"

Anyone know where this ln should go to?

CentOS release 5 (Final) with xen kernel...

Have you installed the relevant [b]kernel-devel[/b] package that matches your current kernel?

[b]yum list avail kernel-devel\*[/b]

and then [b]yum install [i][/i][/b]

HTH.

Yes, I have.

It should go to /usr/src/kernels/2.6.18-53.1.14.el5-xen-x86_64 - as provided by the [i]kernel-devel[/i] package.

You need to go to Section 1 of:

http://wiki.centos.org/HowTos/I_need_the_Kernel_Source

Because you are apparently running a xen kernel, you would run:

yum install kernel-xen-devel

to install the so-called "kernel-devel" package.

That fixed it . Strange. I added the development packages when building the server, strange it didn't pick that dev to add.

Sorry but I work on facts, not assumptions. Typing the command I suggested earlier (you could even have done it with a cut & paste)

[b]yum list avail kernel-devel\*[/b]

would have shown you where your problem was.

This command

[b]rpm -qa kernel\*[/b]

would also have helped you.

I needed kernel-xen-devel.x86_64 to fix my issue.

[AlanBartlett]

Hints are given. Not necessarily explicit steps.

However [b]uname -rmi[/b] and [b]yum list available kernel\*[/b] would have been more precise hints from me. For that, I apologise.

Needless to say when I initially read

I [b]knew[/b] that the correct [b][i]kernel-devel[/i][/b] package had not been installed but, not wishing to cause any offence by just saying "[i]Install the kernel-devel package that matches your kernel[/i]", I phrased it as a rhetorical question.

[quote]Yes, I have.[/quote]

Was not a sensible reply.
