Note that I can save and load sessions fine using exactly the same version of the LS LV2 plugin under (64bit compiled) qtractor running on the same system.

 It may be because I'm still running the last AV5 RC version (which I believe to be identical to the final release) on this laptop but the LS LV2 included in AV5 never did work under A3 or qtractor so I've just ripped it out and replaced it with the latest svn version and it works fine under both A3 and qtractor 32 bit including loading A3 sessions that use LS so this looks like this could be a x64 specific bug.

drobilla has verified this to be a problem and apparently he managed to fix it on his system by patching LS but his patch didn't work for me, he wasn't too certain if he was patching the correct thing and he says he's not familiar enough with LS to know what could be causing the crash for certain. I'm awaiting feedback from the main LS dev for hope of a definitive fix for 64-bit A3 users.

I've had some feedback off the lead LS dev now. Unfortunately he doesn't have time to build A3 and test this bug atm but he does say there isn't a single LS function contained in the above backtrace. That combined with the fact that the same LS build works fine under 64bit qtractor says to me it probably is an A3 bug.

Just been speaking to Leigh on IRC and he says that the LS LV2 works fine for him under 64bit Ubuntu 11.10 but he actually hasn't compiled LS since he was running 10.10 which he has dist-upgraded to 11.10 so maybe this is specific to 64-bit Debian (Testing)?

That was the good news - things have actually got worse under Deb testing 64 since I last tried. Now, the first time I try inserting the LS LV2 the A3 log box pops up with the error:

[ERROR]: LV2: Failed to instantiate plugin http://linuxsampler.org/plugins/linuxsampler

Then if you clear that error and try again A3 (10306) crashes with the error:


lilv_plugin_instantiate(): error: Failed to open library /usr/lib/lv2/linuxsampler.lv2/linuxsampler.so (/usr/lib/linuxsampler/liblinuxsampler.so.3: undefined symbol: _ZN3sf26Region11GetEG2DecayEPS0_)
Segmentation fault


I can start linuxsampler from the cli OK and that shared lib is where its supposed to be.

All signs point to dirty build LinuxSampler build. Please ensure you have ONE copy of LinuxSampler installed, and it is truly a fresh build from a fresh source tree.

I notice your linuxsampler library is in /usr. What are you using to package before installing?

 That latest error comes from latest svn LS (well it was last week anyway - 2277 iirc) but with (lib)Linuxsampler(dev) patched with your patch which you said fixed it for you under Deb Testing 64. I was careful to uninstall liblinuxsampler, liblinuxsampler-dev and linuxsampler before I installed the patched versions of the three packages (LS install creates 3 LS deb packages) yes. Surely there is no need to recompile and re-install all the other libs if they didn't get patched/ updated too?

I made sure before I installed LS originally that LS nor any of its deps (libgig etc etc) were installed and I installed every one from a fresh svn checkout, following their install instructions and even making and installing from Debian packages, which is something I rarely do. I used exactly the same by-the-book installation procedure to install it under Deb squeeze 32 (AV5) and it works fine there.

I can only presume LS is working fine for you under the latest A3 svn then drobilla? With your patch still applied?

 drobilla:

Before installing LS last time I did notice that all of the LS deps are in the Debian repos and seem to be up-to-date. If I'm trying this again maybe I should install everything else from the repos then just compile/install LS from svn?

I've now tried compiling the latest svn LS against the libgig in Wheezy but it doesn't work so yes, all LS components do indeed need to be compiled afresh from svn.

I discovered that LS has actually been updated since I originally filed this bug to 2279 so I uninstalled all LS components and compiled and installed them all from scratch yet we are back to square one in that now I can load and use the LS plugin OK again but I get a segfault as soon as I try loading a session containing the plugin under A3 10313.

I can provide another backtrace although I suspect it'd be the same as above?

In fact, I suspect this backtrace could be more revealing than the previous one. It is actually from A3 10313, despite what it says:

I noticed this second bt made reference to InstrumentResourceManager.cpp which is what drobilla's LS patch modified. Seeing as I seemed to get a different result with this build I thought it would be worth trying the patch again but it hasn't fixed the crash here.

 Here is another similar error. I am using Ardour3 Rev 10443 with AVLinux 5.02. I get a crash when loading a session which has a linuxsampler lv2 plugin which is trying to load the Salamander grand piano. Crash message is below. Session did work with Linuxsampler (+Pianoteq on separate track) when I created it, but I cannot load session anymore due to crash.

EdwardDiehl, can we get that session file?

I've attached a session file (new.tgz) with the linuxsampler crash. This was made with rev 10493. The error does not always occur. Sometimes the session loads, sometimes segfaults, sometimes hangs while loading. I'm using AVLinux 5.02 with the Linuxsampler version 1.0.0+cvs2277avlinux-1, and libgig 3.3.0+cvs2277avlinux-1.

You could maybe try the patch (for linuxsampler) attached to bug 4462; that might help.

 This issues description is no longer accurate. I can now load a session containing the unpatched linuxsampler svn 2283 LV2 plugin under A3 10610 without any errors although it doesn't actually work. No errors appear in the log or the terminal but no sound is produced so it looks like LS doesn't get started.

The patch attached to 4462 applies cleanly but LS doesn't compile after being patched as I suspect the Debian (testing/sid) lv2core package I'm using isn't new enough. I'll try again when it gets updated to have the state extension.

I have same problem of missing lv2_state.h also using Debian (AVLinux). Cannot figure out what package might contain lv2_state.h. Svn of lv2core does not.

Linuxsampler SVN with A3 SVN works fine for me; is this still a problem?
