Debian "jack server is not running or cannot be started" error

[Okaghana]

Hi there.

I tried to install Löve2d on my Debian VM. I had problems compiling it and so I just installed it via the

Code: Select all

apt-get install love

command. But now when I try to run a file i get this weird error-message in the console:

Code: Select all

~/Desktop$ love lovegame
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock

After this the game starts normally in a window, but as far as I can tell the console doesn't work anymore, which is really annoying for debugging. This happends to all main.lua files I try to execute (and yes, I'm selecting the folder with the main.lua and not the file itself). I even tried to just execute a simple "Hello World" file, but I still got the error messages (like I said, the window works flawlessly).

I looked it up online, but found nothing helpful. On Hint was to kill the pulseAudio and restart jack_control, but my OS dint know the

Code: Select all

jack_control start

command.

I also tried to reinstall Pulseaudio, remove Pulseaudio entirely, reinstall jack (with and without jack-tools), removing jack (still the same error) and removing and reinstalling Löve2d. So far no success.

System: Linux debian 4.9.0-8-amd64 #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux on Virtualbox
löve Version: 0.9.1-4 amd64

Thanks in advance

AFAIK, the jack message is merely a notification, not an error. LÖVE games run just fine despite Jack not being available.

the console doesn't work anymore

What do you expect the console to do? Once a task has been started, it will wait for the task to finish. There is no LÖVE debug console that you could use.

Unless you write one and if you do, do that in a separate thread, unless you want to freeze your application frequently.

But yeah, some third party stuff may dump notifications into the console, and löve can't really suppress them, sadly; usually they're harmless as grump said.

Try editing /etc/openal/alsoft.conf. Look for the drivers=... line and change it to drivers = pulse

Also, keep in mind the prepackaged version is LÖVE 0.9.1, which is quite dated.

Compiling shouldn't be difficult at all. If it stops, it's typically because of a missing xxxxx-dev package.
