Talk:LLA, OpenDMX USB and Q Light Controller Tutorial

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.

Regards,

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:

lla_plugin_info lla_plugin_info: error while loading shared libraries: liblla.so.1: cannot open shared object file: No such file or directory

OR

llad -d 3 -f -s Failed to open lla-universes.conf: No such file or directory Loaded plugin StageProfi Plugin Loaded plugin UsbPro Plugin Loaded plugin Dummy Plugin Loaded plugin OpenDmx Plugin Loaded plugin ArtNet Plugin Trying to start StageProfi Plugin Failed to open lla-stageprofi.conf: No such file or directory StageProfiWidget: could not connect Connection refused StageProfiPlugin: failed to connect to StageProfi Device Started StageProfi Plugin Trying to start UsbPro Plugin Failed to open lla-usbpro.conf: No such file or directory UsbProPlugin: failed to connect to /dev/ttyUSB0 Started UsbPro Plugin Trying to start Dummy Plugin Failed to open lla-dummy.conf: No such file or directory Installed device Started Dummy Plugin Trying to start OpenDmx Plugin Failed to open lla-opendmx.conf: No such file or directory Started OpenDmx Plugin Trying to start ArtNet Plugin 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

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
