Earlier this year I sent a quick fix to the makefile to stop it from tainting the kernel. It was so long ago that I forgot if it was lirc's makefile or ivtv's makefile that needed to be fixed. It was a no-brainer fix, but nobody cared.

Hmm, will that address the no version for "lirc_unregister_plugin" found
error?

Yup.

I did a search on your username and did not find any references to this.

I also check the lirc open source page:
http://sourceforge.net/forum/forum.php?forum_id=16771


Any suggestions on where I might find the fix you posted?

I'll make this short.  My lirc packaging script does this:

==========================================================================

[ unpack, configure, et al ]

# Fix kernel taint due to missing symvers

make -C drivers/lirc_dev

for f in drivers/*/.
do
 test -f drivers/lirc_dev/Modules.symvers || continue
 test -f $f/Modules.symvers || cp drivers/lirc_dev/Modules.symvers 
$f/Modules.symvers
done

make

==========================================================================



Presto.  No more tainted kernels.

Sourceforge's search is crap. I found my original message. It was an lirc makefile fix: Searching the list archives, I find occasional messages going back to 2005 about people wondering why they get their kernel tainted after loading various lirc modules. I'll skip the excrutiating details. To make a long story short, it looks like there's a very easy way to finally bury this bug, starting with kernel 2.6.17, due to some enhancements in the module build system. Rather than running make right off the bat, first, I manually run make in drivers/lirc_dev. Under 2.6.17 -- and under 2.6.17 only -- modpost creates Modules.symvers in drivers/lirc_dev (this is why I test if Modules.symvers was created, so the whole thing gets ignored when building modules for older kernels). I take it, and copy it to all the other driver directories. It would be nice if lirc's Makefile gets fixed to take advantage of 2.6.17's modpost, before the 0.8.1 release.
