OK, I deleted /dev/lirc[x]

IF I

sudo lircd -d /dev/iguanaIR/0

I receive:

$ sudo lircd -d /dev/iguanaIR/0
lircd: can't open or create /var/run/lirc/lircd.pid
lircd: No such file or directory

lircd is pointing to the one that I created:


$ which lircd
/usr/local/sbin/lircd

I removed (using synaptics) lirc before I compiled my own version.

am I not beyond that? I can run igclient with no problem and the IR
transmitter will flash consistently.

What I do know is that the source code for the iguanaIR 1.0-pre- toolset won't even compile without the updated libusb 1.0.0 (I use iguanaIR to blast to dc50x boxes on both Ubuntu and on Slackware machines, for the latter of which I have to do all Mythtv and related installations from source.)


Yeah, from what you say, this could be a problem

 /usr/lib/libusb.so -> /lib/libusb-0.1.so.4.4.4

I do have 1.0, though:

ls /usr/lib/libusb*
2010-04-04 20:33 /usr/lib/libusb-0.1.so.4 -> /lib/libusb-0.1.so.4
2010-05-23 15:11 /usr/lib/libusb-1.0.so.0 -> /lib/libusb-1.0.so.0
2008-11-04 22:42 /usr/lib/libusb.a
2008-11-04 22:42 /usr/lib/libusb.la
2010-04-26 21:03 /usr/lib/libusb.so -> /lib/libusb-0.1.so.4.4.4

ls -/lib/libusb*
2010-04-04 20:32 /lib/libusb-0.1.so.4 -> libusb-0.1.so.4.4.4
2008-11-04 22:42 /lib/libusb-0.1.so.4.4.4
2010-05-23 15:11 /lib/libusb-1.0.so.0 -> libusb-1.0.so.0.0.0
2009-05-15 04:57 /lib/libusb-1.0.so.0.0.0

yuck, no fun. Thanks for the warning.

What should be my next step. Can I just repoint libusb?
