[mythtv-users] lirc_init error running mythfrontend

[mythgnomer at rowelab.com]

Those i2c warnings during lirc compile can usually be ignored, but
unresolved symbols usually means you don't have the kernel sources installed
that match the kernel you're running or compiling against.

http://www.lirc.org/faq.html

What's happenning is that lirc creates loadable kernel modules. To do that,
it has to have the kernel sources to build against. This will also help if
you ever have to compile ivtv manually, or alsa, or.. (lots of stuff).

If you've installed a kernel via RPM, you should also download the kernel
sources RPM and install it. Once that's done, see if there's a symlink from
your kernel sources to /usr/src/linux .. If not..

$> cd /usr/src
$> ln -s linux-<my_kernel_version> linux

Then, you'll need to change over to that directory and run a few commands..

$> cd /usr/src/linux
$> cp /boot/config-<my_kernel_version> ./.config
$> make menuconfig

Don't change anything, just save it. Then..

$> make dep; make clean

That should set up all the headers so that you can compile programs that
create loadable kernel modules.

Subject: [mythtv-users] lirc_init error running mythfrontend

I'm installing MythTV for the first time and have been following Jarod's
guide through the whole process. Every step has proceeded just as he
described, but I'm getting an lirc_init error when I try to start
mythfrontend. The screen flashes blue for a split second as it loads the
myth UI, but it dumps back to the terminal.

I'm using apt-get and all the packages specified in Jarod's guide, so I have
the ATrpms custom kernel, nvidia drivers, mythtv-suite, lirc, alsa, etc etc
installed just as he instructed.

I installed lirc via the apt-get command mentioned in Jarod's guide and got
no error messages. I configured it to use a Hauppauge remote, even though I
don't have one yet. I had no complaints or error messages at any step.

mythconfigure worked fine and it found my tuner and assigned channels,
mythfilldatabase worked fine (AFAIK), and mythbackend runs without
complaints. But when I run mythfrontend, I get the lirc_init error.

One strange thing is that /var/log/messages is showing entries from lirc
0.7.0pre1. Wasn't apt-get supposed to install 0.7.0pre2? I did this step
exactly as in Jarod's guide though...

Thinking that lirc somehow didn't get installed correctly, I grabbed lirc
0.7.0pre2 from lirc.org and installed it, but it wouldn't compile.
It kept complaining about i2c errors and unresolved symbols (lots of inc_use
and dec_use problems, plus more). But the ATrpms kernel has i2c support
installed, doesn't it? Just in case, I tried to re-compile the ATrpms
kernel, but that completely broke my system (no nvidia gfx, and I couldn't
get the driver to re-compile under the custom kernel, etc.), and it didn't
fix the lirc compile problem anyway. I went back to the standard ATrpms
kernel, and installed the latest version of the i2c package and tried to
recompile lirc, but that just made even more of a mess, so I'm in the
process of starting over from scratch now.

Anybody have a clue? Sorry I'm a bit of a newbie, though not totally
unfamililar with linux, I'm no expert either. My install was hosed and I'm
currently reinstalling FC1 right now, so I'll post the exact specific error
messages I was getting, next time I see them.

Thanks,
Jason

P.S. I'm using a Shuttle SN41G2 (nforce2 board) with onboard gfx & network,
my tuner is supported by a patched ivtv and is working fine outside of
mythtv.
