Installation & Configuration Linux
#1

Hello everybody, it’s my first time on a forum, so I certainly did it wrong…

I have a problem with Ardour3, I’ve find lot of forum with the same problem, but I’m to novice et Linux to understand everything…

I’m using Lubuntu 14.04 LTS,
I’ve a kernel low-latency, I’m using qjackctl, I’m on ardour3.

Opening a new session is not a problem, but reopening an old one is impossible :

bnd txt domain [gtk2_ardour3] to /usr/share/locale Ardour3.5.403~dfsg-3~ubuntu14 (construit avec 3.5.403~dfsg-3~ubuntu14.04.1 et GCC version 4.8.2) ardour: [INFO]: Your system is configured to limit Ardour to only 4096 open files ardour: [INFO]: Loading system configuration file /etc/ardour3/ardour_system.rc Loading user configuration file /home/astrapi/.config/ardour3/ardour.rc Using SSE optimized routines /usr/share/themes/Lubuntu-default/gtk-2.0/assets/pcmanfm.rc:29: error: unexpected identifier 'hint', expected character '}' (ardour-3.5.403~dfsg-3~ubuntu14:3797): GLib-GObject-WARNING **: Attempt to add property gtkmm__CustomObject_N9Gtkmm2ext25CellRendererColorSelectorE::color after class was initialised ardour: [INFO]: Chargement du fichier de style par défaut (/etc/ardour3/ardour3_ui_default.conf) pour l'interface graphique Loading ui configuration file /etc/ardour3/ardour3_ui_dark.rc /usr/share/themes/Lubuntu-default/gtk-2.0/assets/pcmanfm.rc:29: error: unexpected identifier 'hint', expected character '}' Found nothing along /home/astrapi/.config/ardour3/templates:/usr/share/ardour3/templates run dialog Scanning folders for bundled LV2s: /usr/lib/ardour3/LV2 (ardour-3.5.403~dfsg-3~ubuntu14:3797): GLib-GObject-WARNING **: Attempt to add property gtkmm__CustomObject_N9Gtkmm2ext23CellRendererPixbufMultiE::active after class was initialised Erreur de segmentation (core dumped)

I’ve install calf-plugin (i’ve tried to remove it and that doesn’t work).
I’ve my audio group memlock set to unlimited

I don’t know what to do… :’(
Please help me !

#2

I’ve done that :

Il va falloir modifier 2, 3 bricoles sur le PC pour pouvoir améliorer les performances de traitement en temps réel. Par exemple si au lancement d’Ardour, vous avez le message suivant

AVERTISSEMENT : Votre système possède une limite supérieure pour la quantité maximale de mémoire verrouillée.
Ceci peut empêcher Ardour d’accéder à de la mémoire avant que la mémoire disponible sur votre système ne soit épuisée.

Vous pouvez voir la limite actuelle avec la commande « ulimit -l » et celle-ci est habituellement contrôlée par le fichier /etc/security/limits.conf.

Il faudra éditer le fichier /etc/security/limits.conf et rajouter à la fin (ou modifier)

ALREADY DONE BEFORE

Real Time support for audio group

@audio - rtprio 90
@audio - memlock unlimited

vos utilisateurs doivent être impérativement également dans le groupe audio. Maintenant on rajoute à la fin du fichier /etc/rc.d/rc.local les lignes suivantes

I did it with nano because it doesn’t work like that (vim wouldn’t do it, I don’t know why…)
echo 2048 >/sys/class/rtc/rtc0/max_user_freq
echo 2048 >/proc/sys/dev/hpet/max-user-freq
echo 0 > /proc/sys/vm/swappiness

Maintenant sous /lib/udev/rules.d j’ai créé le fichier 40-rtc-permissions.rules qui contient

KERNEL==“rtc0”, GROUP=“audio”

j’ai créé également le fichier 40-hpet-permissions.rules qui contient

KERNEL==“hpet”, GROUP=“audio”

Maintenant j’ai édité le fichier /etc/sysconfig/pulseaudio et j’ai mis

PULSE_SERVER_TYPE=none

But it was useless…

#3

I’ve tried something else, I create a new session, and replace the *.ardour by the old one (the one where I was working on), and
put the midi files in the good folder , and that give me the same error. (if it can help…)

#4

The problem is likely fixed in a newer version of Ardour. Please stop using 3.5.X and start using 4.2. Additionailly, if you are using plugins, then the crash is likely caused by one of them (notably older versions of the CALF plugins). You can try out a demo copy of the current version of Ardour via http://nightly.ardour.org/

#5

Wonderful, I try this right now !
Thank you !

#6

It woooooorks !!!
Lag a little bit but it works !
I used it like that and will upgrade with paid version thanks a lot !

#7

Hello , sorry to bother you again…

I only call for help, but I can say too that it’s my first time in giving money to a software ! (Ok it’s not very much… But I’m a bit poor… :smiley: ) So that mean
that I find your (your like all the people who made this Ardour) software REALLY wonderful ! It’s better than every think I tried before, very very flexible (that’s what I like most, changing tempo every time or less etc…) So thank you all !

I’ve a little problem, Ardour (4.2.0) failed often (but during utilization):
write failed, drop flushed note off on the floor, time 547 > 0
Erreur de segmentation (core dumped)

It’s a bit frustrating… But maybe my computer is not enough strong…
Processor : 2x Intel® Core™2 CPU T7200 @ 2.00GHz
Memory : 2049MB
Operating System : Ubuntu 14.04.3 LTS
Audio Adapter : HDA-Intel - HDA Intel

Can you help me ?

#8

Ok I’m sorry, I’ve read you badly, my calf-plugins are version 0.0.19 so note enough, I will try to upgrade it (if I find how…)

Arrrrh… please help me :""(
I download on github calf-plugins (0.0.60), unzip it.

$ cd to the folder
$ ./configure
$ ./make

./make install

no problem I though,
When I start calf monosynth (the one I need I think for loading titanic.sf2 bank (or an other)), Ardour crash…

If I try to run calf in gui mode, he crash when I select a plugin. (At least it’s not ardour fault :smiley: , certainly mine :frowning: )
#10

Maybe you have calf-0.19 in /usr/lib/lv2 (from the distro) while your custom version is in /usr/local/lib/lv2 ?
duplicate plugin results in undefined behavior.

In any case: http://ardour.org/debugging_ardour would at least tell where and why ardour crashes.

#11

Thank you, I had a folder /usr/lib/lv2, I removed it, I uninstall calf-plugin,
I unstall lv2-core, compile myself (youhooo !) lv2-core v6
I compile and install calf-plugin from http://calf-studio-gear.org/ , get the one that they say :

$ ./autogen.sh
$ make -j2

make install

didn’t work at all…
Took the one from github (calf-master)
And did

$ ./autogen.sh
$ make
$ sudo make install

… (Linux is not an easy one…)

Annnnnnd YOUHOOOOUUUU !!! That’s woooork !!! Wonderful :smiley: , it was certainly the old /usr/lib/lv2 who was in conflict (well done :smiley: )
Thank you :smiley:

It’s when I move the cursor during the playing (the sound make a “bzzzzzzzzz” and Ardour crash)

#13

I’ve find a way to make it crash each time, I play and in the same time I change the button in shift-e, next to group : personal, post, out, in

I try tobuilt myself gdb (because I can’t have it by apt-get (problem of dependencies :
Les paquets suivants contiennent des dépendances non satisfaites :
gdb : Dépend: libpython3.4 (>= 3.4~b1) mais ne sera pas installé
E: Impossible de corriger les problèmes, des paquets défectueux sont en mode « garder en l’état ».

I’ll be back with more information about the crash I hope

#14

SO ! I install gdb :

Is this help you ? …
#15

The note messages are unrelated, and unrelated to crashing.

You do not need to build Ardour yourself, you can simply download the free/demo + Debug version from http://nightly.ardour.org.

When pasting output from gdb, it is more helpful to include the several lines before you were able to type “thread apply bt all” which show where the crash is actually happening.

#16

Ok so I give you some useless information…
I-ve already download this version (that I found where you told me, but it’s not the demo version (I became subscriber (a little one)) :
$ Ardour4 -v
bind txt domain [gtk2_ardour4] to /opt/Ardour-4.2.0/share/locale
Ardour4.2.0 (construit avec 4.2 et GCC version 4.4.7)

the result from the bug before I type thread apply bt all :
Set buffering params to 262144|131072|10|10
Skip explicit buffer seconds, preset in use

I hope it was what you ask… Thank you again for your help !

#17

Sorry, I come back to you…
If I touch the panning during the audition, I freeze and I’ve this message repeating :

JackAudioDriver::ProcessGraphAsyncMaster: Process error JackAudioDriver::ProcessGraphAsyncMaster: Process error JackEngine::XRun: client = ardour was not finished, state = Triggered JackAudioDriver::ProcessGraphAsyncMaster: Process error JackAudioDriver::ProcessGraphAsyncMaster: Process error JackAudioDriver::ProcessGraphAsyncMaster: Process error

If someone knows what is happening…

Thanks again for helping :slight_smile:

ps : I try to install the new version 4.4 maybe that will heal everythink ^^
#18

It’s look like to be better ! Good job all folks !
