Q Light Controller+

I tried to install the 4.4.0 beta, as well as the 4.3.3 stable version of QLC+ on a newly created version of Debian Linux (Debian-Live-7.0.0). It failed with a dependency error, complained that I needed Libc6 version 2.15 or higher, but I have 2.13. It appears that version 2.15 is not readily available, according to what I googled around.

I tried "apt-get install libc," and it tells me I have the latest version.

Am I missing something something? Thx.

As you probably know .deb files are used on Debian but also on Ubuntu.
In fact QLC+ is compiled on Ubuntu 12.04 32 and 64 bit.
When dependencies are not satisfied, it means you need to compile QLC+ from sources. Doing it in Linux is quite easy:

I've successfully compiled QLC+ on Ubuntu 10.04 64bit which should be quite similar to your Debian 7. Unfortunately I don't have direct access of that system to help you in a decent time

Hi!

Had the same problem installing qlcplus on Debian Wheezy, so I tried to build it. Installed all stuff I was told to install by the first run of create-deb.sh... On the second run, I got an error:

...any guess?

I solved this problem (making package directly from the git tree) by using apt-get install libfftw3-dev. The dependency was somehow not in the package.

Yeah, it's actually written in the Wiki: https://github.com/mcallegari/qlcplus/w ... uild-HOWTO

alternatively, you can try changing file: qlcplus/debian/control:

Change:

> Build-Depends: debhelper (>= 7.0.50), libqt4-dev (>= 4.6.0), libasound2-dev (>= 1.0.16),
> libusb-dev (>= 2:0.1.12), libftdi-dev (>= 0.17), shared-mime-info (>= 0.71),
> make, g++, libstdc++-dev, libudev-dev, libmad0-dev, libsndfile1-dev, liblo-dev

to

Not tested, I'm not at my linux machine.

Got it! There is a little misstake: libmad-dev is not in the debian-repos, but libmad0-dev is.

Also, I couldn't get OLA compiled so I took the deb packages they're offering, see: http://opendmx.net/index.php/Download_&_Install_OLA

Unfortunately, no repo-keys.

Anyway: Installed the ola-dev package, tried to build qlcplus, again and got stuck, again:

Don't know: Is it necessary to compile the ola-plugin for my Enttec DMX USB Pro? If yes: What to do, now?

Update your QLC+ tree. I've fixed this 2 days ago.
The kind guys of OLA changed the data structures so now we're all forced to use version 0.8.30. :S

And no, OLA is not needed for your USB device. You can comment it out on plugins/plugins.pro file
