JoeboyTrying to check out the drobillad repo, I get:16:40
JoeboyCloning into 'jalv'...16:40
JoeboyChecking connectivity... done.16:40
Joeboyfatal: reference is not a tree: cd67471b63d81a1acb0a0f96dc960dcce21519bb16:40
JoeboyWhen I do git submodule update.16:41
OpenAVJoeboy: haven't cloned drobilla repo recently - do a git checkout master?16:43
OpenAVit looks like you're trying to grab an exact commit that doesn't exist16:43
*** ricardocrudo has quit IRC16:43
* OpenAV gotta go now, that's all I can think of though16:43
JoeboyOpenAV: That's on a fresh clone :-(16:44
*** falktx|work has quit IRC16:44
OpenAVhmm, in that case drop drobilla an email16:44
OpenAVJoeboy: ^. No other ideas, gotta go. Laters!16:44
JoeboyOk, cheers16:44

Felix__hey21:34
Felix__anyone here?21:34
falktx`not sure21:40
ssj71what sort of people are you looking for? Theres *someone* here21:42
Felix__I'm struggling with my raspberry setup21:42
Felix__I could need some advice to achive my goal to make an rpi, hosting a lv2 plugin and streaming audio over my cirrus sound card21:43
falktx`errm, that might be a better question for a mailing list..21:44
falktx`lau or lad21:44
Felix__Mhh21:44
Anchakorfor the lv2 things, you can use jalv as a host21:44
Felix__Jep, thats what I'm struggeling with right now21:45
Felix__I have to admit, that I'm pretty new to linux21:45
Felix__and I didn't made it to that point, where I can use lv2 plugins and/or jalv21:45
ssj71jalv depends on JACK IIRC, do you have jack set up?21:46
Felix__Could you give me some points to look up for how to install those21:46
Felix__Yes21:46
ssj71so your current trouble is building jalv21:46
Felix__Got the jack-server working21:47
Felix__Yes21:47
ssj71can you pastebin the output when you try to build?21:47
Felix__I've read, that I should run lv2ls to list my lv2 plugins. But the command is not available at the moment21:47
Felix__according to that console output, I might install someting else first21:48
Felix__Is that right?21:49
Felix__Something like that: http://lv2plug.in/spec/lv2-1.12.0.tar.bz2 ?21:49
ssj71I'm not sure if the lv2ls utility is in the lv2 repo or some lv2-tools or something21:51
ssj71you'll need lv2 for compiling jalv though I figure21:51
ssj71doesn't look like lv2ls is in there21:53
Felix__So, how can I install lv2 (damn, noob question...)21:53
Felix__?21:53
Felix__-.-"21:53
Felix__apt-get ?21:53
grejppilv2ls is in lilv IIRC21:53
ssj71Felix__: depends on what distro you are using. I assume raspbian?21:53
ssj71makes more sense to be there21:54
Felix__raspbian21:54
ssj71you can try apt-get install lv221:55
ssj71you can hit tab and see if it autocompletes with any packages. I'm a little doubtful its in there, but I've been wrong many a time21:55
Felix__this doesn't work21:55
Felix__ok21:55
Felix__autocompleting does not work21:56
Felix__and there is no "lv2" package available21:56
ssj71looks like liblilv is in raspbian21:56
ssj71apt-get install liblilv21:57
ssj71su or sudo if you aren't root21:57
ssj71that will give you lv2ls21:57
Felix__sure21:57
Felix__I'll give it a try21:57
ssj71seems jalv is there too21:57
*** edogawa has quit IRC21:58
ssj71http://www.raspberryconnect.com/raspbian-packages-list/item/91-raspbian-sound21:58
Felix__no such packet21:58
Felix__i tryed: sudo apt-get install liblilv21:58
ssj71did you do sudo apt-get update?21:59
ssj71not sure how up to date that list I found is. I've never really played with a PI21:59
Felix__ok21:59
Felix__just a sec21:59
Felix__updating in progress22:00
Felix__updating didn't made me finding that liblilv packet22:01
Felix__:/22:01
ssj71I assume you tried "sudo apt-get install jalv" as well?22:02
Felix__This is horrible. I was so happy, when I made my pi to talk to my audio card and now ...22:03
ssj71Felix__: don't stress it. These things take time. Especially when you are new to it22:03
Felix__thanks for your words and help, dude22:04
Felix__Ok, this is strange22:04
Felix__now my pi sais, that jalv is installed22:04
*** Felix_pi has joined #lv222:06
Felix_piok22:06
ssj71there you go :)22:06
Felix_pithe following packages seemed to be installed:   liblo7 liblv2dynparamhost1-1 libqt4-designer libqt4-script libqt4-svg22:06
Felix_piand jalv is up to date22:07
Felix_pibut I still can't use that lv2ls command to list my plugins22:07
grejppiFelix_pi: 'dpkg -S lilv' tells me it's in lilv-utils22:08
Felix_pigreat!22:09
Felix_piI've installed the package and it works22:09
Felix_pi<322:10
grejppiawesome22:10
grejppi('dpkg -S lv2ls' I mean but whatever)22:11
Felix_piBut how do I manage to start a plugin?22:12
Felix_piI've tryed to install the eq10q equalizer22:12
Felix_pipi@raspberrypi:~ $ lv2ls http://eq10q.sourceforge.net/compressor http://eq10q.sourceforge.net/eq/eq10qm http://eq10q.sourceforge.net/eq/eq10qs http://eq10q.sourceforge.net/eq/eq1qm http://eq10q.sourceforge.net/eq/eq1qs http://eq10q.sourceforge.net/eq/eq4qm http://eq10q.sourceforge.net/eq/eq4qs http://eq10q.sourceforge.net/eq/eq6qm http://eq10q.sourceforge.net/eq/eq6qs http://eq10q.sourceforge.net/gate22:13
Felix_piWhy does this list weblinks? I thought I could use the lv2 offline...22:13
Felix_piand...22:13

Felix_pipi@raspberrypi:~ $ jalv http://eq10q.sourceforge.net/eq/eq10s Plugin:       http://eq10q.sourceforge.net/eq/eq10s Failed to find plugin22:14
ssj71Felix_pi: lv2 plugins each have a unique identifying string, typically its a website address22:16
Felix_piOk22:17
ssj71right now it looks like you only have the eq10q plugins installed22:17
ssj71to use jalv, just type "jalv http://eq10q.sourceforge.net/compressor" or whichever plugin you want22:17
grejppiFelix_pi: you have a typo there, eq10s instead of eq10qs22:18
ssj71you might look into jalv.select which will give a little bit easier experience than the command line22:18
Felix__ok22:18
* grejppi is lazy and usually does something like: jalv `lv2ls | grep eq10qs`22:19
ssj71yup22:19
Felix__ok22:20
Felix__jalv.select isnt working for me22:20
grejppiit's an external program22:21
grejppiisn't it22:21

grejppiyay, it's running!22:26
Felix_piagainyeah! but there's no gui :/22:26
*** NickSB has joined #lv222:26
Felix_piagainand there're some errors22:27
Felix_piagaindo you guys know, how to enable the gui of that plugin?22:28
grejppioh, you could try jalv.gtk22:28
Felix_piagainsure. heard of that22:28

ssj71jalv doesn't show a gui. jalv.gtk will22:32
ssj71its probably installed with jalv22:32
Felix_piagainjalv.gtk $(lv2ls | grep eq10qs)22:33
Felix_piagainthat's what I've tryed22:33
ssj71you could try jalv.qt just for experiment22:34
Felix_piagainsame story22:34
Felix_piagainjalv.qt $(lv2ls | grep eq10qs)22:35
Felix_piagaingave me the same errors22:35
Felix_piagainand still no gui22:35
grejppihmm it could be something in the plugins themselves...22:36
grejppibrb22:36
Felix_piagainI've also tryed to launch the compressor (this was preinstalled, right?)22:36
Felix_piagainsame thing22:37
ssj71Felix_piagain: odds are if they're from the same plugin pack they'll have the same bugs22:37
ssj71Felix_piagain: and I know the eq10q series had some big bugs in the older versions. Not sure what version you installed22:38
ssj71they only reached 1.0 in like december I think22:38
Felix_piagainjust by the way, you guys are awesome! even though not everything is working, you guys pushed my little project for days22:38
Felix_piagainok. maybe I've made some mistakes during the installation process22:39
Felix_piagainis there an easy way to uninstall the plugins?22:39
ssj71depends on how they were installed, but typically you can just delete the folders that contain them22:45
ssj71they are usually in /usr/lib/lv2/22:45
ssj71careful not to delete the wrong thing!22:45
ssj71:)22:46
Felix_piagainmhh not on my pi... :/22:47
ssj71if you installed manually probably /usr/local/lib/lv222:48
Felix_piagainahh got it22:48
Felix_piagainapt-remove eq10q did the job22:48
ssj71ok, thats the safer way22:49
Felix_piagainbut as i've made apt-get update earlyer, the eq10q plugins was at the latest version, would that be true?22:50
*** Magnus_RM has quit IRC22:53
ssj71Felix_piagain: only if the packager updated the package22:57
Felix_piagainok22:57
ssj71I'd try a different plugin22:58
Felix_piagainthat what I'm doing right now22:58
Felix_piagaindamn, it works!22:59
Felix_piagainthis is awesome!23:00
Felix_piagain100%23:01
grejppigreat!23:04
Felix_piagainas an additional thing. does anyone know, how to set a specific jack connection a startup standart?23:06
ssj71you can do it with a script. There's probably a better way though23:07
Felix_piagainthat was my thought23:07
Felix_piagaingonna do that tomorrow23:08
Felix_piagainThanks for your guys advice :)23:08
ssj71np23:11
rgareusjack.plumbing  or qjactctl's patchbay  can make connections automagically23:12
rgareusbut jack_connect the commandline tool would be my tool of choice23:12
Felix_piagainok23:13
Felix_piagainmaybe I'll give a try right now23:13
Felix_piagainfck the thing that I'll be at work in 6hours :D23:14
Felix_piagainanyone knows why jack_connect works like a charm and jack_port_get_connections doesn't?23:33
