I have an 11.2 system that I want to use to compile a kernel driver. The

I guess I can get the proper version compiled if I install the desired
kernel headers. I do not in any way want to replace the existing kernel
install. All I want it a parallel install of the headers needed to do my
compile.

I have the RPMS that are needed:

kernel-default-devel-2.6.31.14-0.6.1.i586.rpm
kernel-source-2.6.31.14-0.6.1.noarch.rpm
kernel-syms-2.6.31.14-0.6.1.i586.rpm

Would these be enough? The kernel-source and kernel-syms match the
current kernel (I am fairly certain). It is the kernel-default-devel
that I think is the issue.

Can I install these so that they do not mess up the installed kernel,
but are in the expected directories for their version of the kernel?

Roger,

Have you just tried it?

You mean install RPMs for a kernel other than the one installed? And
trust that the install does not do anything like replace part of the
kernel with this alternate one? Trust that there is no gottcha in one of
them that messes something up when installing multiple versions? Nope.
Not without doing a bit of checking first. My version of measure twice,
cut once.

I would expect the devel packages between -default and -desktop to be
near identical if not identical. The fundamental difference between
them I believe is the config files. They call for different modules,
etc.

But the headers and actual source is the same as far as I know.

I would have thought so as well. I am just worried that one of them
might do more than simply install files in some directory.

I think I will try to locate the source RPMs so I can check for the
running of any scripts or other surprise activity.

OOC, what is the minimum set of kernel packages that are needed to
compile a kernel module outside the kernel source tree? Is it enough to
install kernel-source and kernel-XXX-devel?


Yours sincerely,

Roger Oberholtzer
