[mythtv-users] clueless about building modules (lirc on Debian)

[Lorrin Nelson]

Hi - I see there's lots of lirc discussion in the archives, but I don't 
think this has been covered yet. I'm trying to get lirc going under 
Debian Woody (2.4.20-3-k7 kernel). As far as I can tell the way is to 
build a kernel module by hand so that's what I'm trying to do. I've got 
a Hauppauge WinTV-Radio (401) so I'm trying to build the ic2 lirc 
module. I think I might be on totally the wrong path or missing some 
crucial first step. :-(

I did apt-get install kernel-source-2.4.20 and now have the source for 
my kernel in /usr/src/kernel-source-2.4.20. I symlinked /usr/src/linux 
to point there as well.

Then I did apt-get install lirc-modules-source, and the screens there 
offered to build the modules. But no luck:
##### Couldn't build LIRC kernel modules #####

I tried setting TOPDIR (export TOPDIR=/usr/src/modules/lirc) but that 
didn't seem to make much difference:

spiff:/usr/src/modules/lirc# make
make -e -C drivers SUBDIRS="lirc_i2c lirc_dev"

Any help is appreciated!
