No, you want lirc_serial to be a module, and the new "lirc_serial" 
module should be created by your compile.

Assuming that Mandrake didn't de-modulize "lirc_serial.o" there must be 
other things that need to be resolved.

I don't think this is correct. On my system /dev/lirc is NOT a link to 
the serial port, it is a character device. Also, lircd is a socket 
device on my system.  As follows:

crw-r--r--    1 root     root      61,   0 May 24 21:57 lirc
srw-r--r--    1 root     root            0 May 28 00:08 lircd
prw-r--r--    1 root     root            0 May 24 21:57 lircm

I don't know why the install didn't make the correct devices.  You could 
create the lirc device with mknod, but I would be concerned about why it 
wasn't created during the install.  I don't know how you would go about 
creating a socket device.  Maybe remove those strange ones and run make 
install again?

I believe 
"/lib/modules/2.4.21-0.13mdk/kernel/3rdparty/lirc/lirc_serial.o.gz" is 
the Mandrake module.  AFAIK, the standard lirc doesn't generate a 
gzipped module, or put it in that directory.  I would clobber or rename 
that file, and remove any reference to it in modules.dep, or if 
necessary put your newly compiled module in its place.

I'm pretty sure that this is the Mandrake lirc_serial module looking for 
the "/dev/lirc" directory which I think you have removed

AFAIK, you shouldn't have to recompile the kernel.


If you still can't resolve this could you send me a copy of the output 
from the lirc make and make install, and a copy of your modules.conf
