lirc kmdl build...?

I'm probably being stupid, or just don't know the right magic, but how
should I go about building the lirc kmdl package? I need to because I've
built my own kernel rpms.

I'm using CentOS 5, I've installed atrpms-rpm-config-168-1.noarch.rpm
and am trying to follow instructions from
http://people.atrpms.net/~pcavalcanti/LCG_kernel_modules.html in
particular using bkmdl.sh, but the build seems to go on forever,
presumably in circles. I've spotted the following FATAL in the output:

Making install in lirc_serial

`/home/john/rpmbuild/BUILD/lirc-0.8.3/drivers/lirc_serial'

What to do?

Many thanks in advance,

Re: lirc kmdl build...? [In reply to]

John,

The rpm appears to be needing root permission to build the rpm.. The is
really bad practice. don't quote me but I pretty sure that all rpm's
should be able to build w/o root access according to rpm standards.

Two options as I see it..

1. Run rpmbuild as root
2. Fix the spec file so it doesn't need to touch anything system wise
during the compile/make process of the rpm.

Having said all this, I haven't look the spec file and I maybe
completely wrong...

Just my $0.02

Regards,

Peter Tiggerdine.

Yeuch; as you say that's not good practice.

Done that; in a sense it's not a problem with the spec file but the lirc
build process attempts to run depmod after the install phase, which is
not useful during rpm building, so I added "depmod=/bin/true" to the
spec file's configure command.

No, quite right. Having looked more closely I now see why it looked like
the build was going round in circles: building the kmdl package seems to
need to run configure; make; make install for each individual kernel
module, which seems overkill. I might have a go at rewriting the spec so
everything gets run only once, optionally building the kmdl package
depending on a switch, unless anyone here can tell me why it is done the
way it is. If I do I shall be back with more questions when I make the
inevitable stupid mistakes.

Cheers,

John.

I can not help much, because I only build kmdls for Fedora.

But, basically, for lirc, you need the complete kernel tree.
You do not need to compile the kernel, but you need to follow the howto
until

make mrpoper
make modules

Then you can build the kmdl for lirc.

I have built lirc myself in the past, and never had any issue, but as I said
not for RHEL.

Now I've added the "depmod=/bin/true", it all works, and it doesn't need
the complete kernel tree, it's working from /usr/src/kernels/blah from
the kernel-devel rpm I built.

Well, EL5 is effectively FC6, so I'd expect the same issues would occur.
Do you build as root?

Cheers,

John.

Yes. I compiled it for F8 and it is not requiring the complete kernel
anymore.

A lot simpler (and faster) this way ...

I never build anything as root. Sometimes I use mock 0.8.15.

Well, it does say "ignored" which means that make doesn't consider it
really that fatal. :)

Not the cleanest approach, but it's just a cosmetic bug.

No, that's not the case. The failing op is not needed. Yes, as root it
would succeed but it would be a noop and its failure is ignored
anyway.

Exactly. That's the way all rpms at ATrpms are built.

Well, you already explained it: Otherwise you don't get all kernel
modules built. If you find a shorter way to reach the same results I
don't mind changing the build procedure :)
(it needs to cover the current profile, e.g. building only for a given
driver doesn't count - the package needs to be cosumable on the binary
level, not the source-build-it-yourself :)

Your questions are welcome! :)
