Is this tutorial minded on a specific interface? That's what the title says :) Although the procedure is similar for other devices.
What is "Erwin Rol's driver" meant to do? (is it to support some specific hardware that is not supported directly by LLA?) LLA uses the driver to support the enttec open dmx.
The first time QLC is run int the tutorial, it is run as root. Why? Good question - this should be removed. I think it was probably added to get around any permissions problems with the devices but this isn't the way to solve the problem.
It would be nice if the intro explained what you can achieve over a default installation of LLA+ QLC from the repositories.

Problems regarding install under kubuntu
Hi there!
I've got a problem while trying to follow the install tutorial. At first, not the device /dev/dmx is created but /dev/dmx0
Secondly, when I try to start the llad, the daemon aborts in the artnet region:
Failed to open lla-artnet.conf: No such file or directory terminate called after throwing an instance of 'std::logic_error' what(): basic_string::_S_construct NULL not valid Aborted
Any idea what this could be? Thanks, CJ --79.245.72.170 15:18, 1 June 2008 (PDT)
Solution found ?
Hi CJ,
Did you manage to get it working in the mean time ?
I have exactly the same problem.

Bruno
Same problem
I had tried to compile it from source or to use the debian packages. but in both situations, I get the same problems:

works for me now!
first, you have to use an older version of lla (0.2.1). second, when you get the error
error while loading shared libraries: liblla.so.1: cannot open shared object file: No such file or directory
you have to set symbolic linksfrom the newer lib-path (usr/local/lib) to tne older path (usr/lib)
for example: ln -s /usr/local/lib/liblla.so.1 /usr/lib/liblla.so.1

Claudio
This is what I did to make it work
So I had the same error with Failed to open lla-artnet.conf,
I found that in ~/.lla/ there was only one config file, and no lla-artnet.conf
so I booted up the live cd and explored in /root/.lla/ is the .conf files for lla I made a tar of that directory and copied it, and extracted and it worked,
anyways here is a link to the lla config files [1]
Jason
why run llad as root?
In the section "put it all togethere", all the lla commands are run with (graphical) sudo, but is this necessary, even with Erwin Rol's driver for the Linux kernel? Can someone with a Enttec Open DMX interface check this?
- The default port for the web interface is 80. Sub-1024 port assignments require root access. Speaking of which, if anyone knows the way to remap that port, I'd be grateful.
git-clone
you may want to replace git-clone by git clone
cant find build directory on ubuntu
the error is make -C /lib/modules/2.6.28-17-server/build SUBDIRS=/home/user/dmx-software/dmx_usb_module modules
make: *** /lib/modules/2.6.28-17-server/build: No such file or directory. Stop.
make: *** [default] Error 2
what I did to fix it
sudo apt-get install linux-headers-$(uname -r)
then it worked
