Compiling saa7134 on a CentOS 5 machine

Compiling saa7134 on a CentOS 5 machine

[Mogens Kjaer]

Hello,

I'm trying to compile v4l-dvb for my saa7134 card on my
CentOS 5 machine, and I'm having some problems.

The machine runs the 2.6.18-164.11.1.el5.centos.plus kernel.

It used to work some month ago, now I can't get it to compile.

During make, I get:

   Building modules, stage 2.
   MODPOST
WARNING: "ir_unregister_class" [/home/mk/tv/v4l-dvb/v4l/ir-core.ko] 
undefined!

and when I "make install", reboots (as the wiki suggests), and

modprobe saa7134

I get:

WARNING: Error inserting videobuf_core 
(/lib/modules/2.6.18-164.11.1.el5.centos.plus/kernel/drivers/media/video/videobuf-core.ko):

dmesg says:

ir_core: Unknown symbol ir_unregister_class

The card is a:

# lspci
05:09.0 Multimedia controller: Philips Semiconductors 
SAA7131/SAA7133/SAA7135 Video Broadcast Decoder (rev d1)

and I have a

options saa7134 card=96

in modprobe.conf.

v4l-dvb is today's:

hg clone http://linuxtv.org/hg/v4l-dvb

It used to work a couple of month ago...

Googling ir_unregister_class doesn't tell me anything.

What have I done wrong?

Hm, the following patch "fixes" the problem:

cd linux/drivers/media/IR
$ diff -urN ir-sysfs.c.orig ir-sysfs.c

  module_init(ir_core_init);
  module_exit(ir_core_exit);
+#else
+void ir_unregister_class(struct input_dev *input_dev)
+{
+}
  #endif

I guess this is not the right way to do it - but
the machine boots and the modules load!
