libslv2

Hi Daniel / Quentin. I don't know if you've picked up on this yet but Ardour 2.3 uses a new library, called libslv2 (LV2 seems to be some kind of extension for the LADSPA plugins). It can (optionally) be compiled without LV2 support though. If I type "libslv2" into Synaptic, nothing shows up. If I type "LV2" or "SLV2" it shows me some (irrelevant) libraries relating to Apache network security. Any ideas about where libslv2 can be obtained ? (pref. somewhere compatible with Synaptic).

The fun with SVN is that it has licence to break. I managed to install from there in the past, but lately I tend to keep to the release versions, for 64studio testing purposes. And, after what you told me, I am not going to try that just jet. Project on the go, and I still did not get a separate system for testing only... Check out the ardour site, and / or IRC channel, and ask the guys what you should do next, and if they know about this problem. When I can go online, the IRC is normally empty (or full of guests like me) - timezone problems. Hope you get it right!

Hi Quentin - along similar

Hi Quentin - along similar lines I've noticed some other strange problems when compiling Ardour 2.3. This might be Ardour's fault or 64studio's fault - I don't really know. I used to run Ardour 2.1 which compiled & built without any problems. A few days ago I updated (from Ardour's '2.0-ongoing' branch) using svn update. I've now got version 2.3 (svn 3117). However, when I try to build it, Scons tells me that it can't build the 'libardour_tranzport' branch due to being unable to find libusb. According to Synaptic, libusb is correctly installed (In fact, I have both the C and C++ versions, including their dev packages). To make Ardour build correctly, I needed to delete my previous installation and do a completely fresh svn checkout. I've verified this on 2 x PC's and it was the same on both machines (of course, neither PC had this problem before). The other thing I've noticed is that when I run 'scons install' (after building the UPDATED version of Ardour 2.3) it doesn't seem to install the '.po' and '.pot' files (which I think are something to do with language translations). Again, it used to install these previously. Also (like with the previous problem) I can only get the installation to work properly if I build from a fresh checkout, rather than an update. My gut instinct is that these are probably Ardour problems but I just wondered if you'd encountered them?

Picked up, Yes

When I compiled my own version for testing initially, I did add LV2 support. libslv2 is not in the Debian repositories at the moment, but it could reside under a different name. LV2 is the new proposed standard for linux plugins, and though superior to LADSPA, very little development and/or porting to the new standard has been done. More info... http://lv2plug.in/ You can get the latest debian packages here: http://download.drobilla.net/debian/ I don't know if ardour has been compiled for LV2 support. Possibly not. I'll open a ticket. Cheers,
