Hi,
I just downloaded and installed the latest Ardour self-extracting binary, and it looks great. But when I add a Calf plugin to a track, it crashes Ardour.
The plugins work great in the Calf host, but why is it crashing? Do I need to recompile them against the (maybe slightly) newer libs that come with Ardour? If so, how do I do that?
Thanks for all you guys do,
Fred
Hard to say without a backtrace[1], but there have been various issues with calf plugins in the past. Make sure to use at least calf 0.60.0.
Also make sure that the compiler version matches (gcc4/gcc5). Calf plugins are one of the few which are affected by this change. Ardour gcc5 versions are available from the nightly built site [2].

CALF plugins have been problematic with Ardour for a long time. If you must use them, make sure you are using the versions from CALF git. This fixes a number of problems. As of Mar 2016, this version of CALF has not yet been released. Also, for people reading this who are for some reason using old versions of Ardour, be sure you are using a current version of Ardour (4.4 or newer).
Thanks. I’m running Calf 0.0.60pre5, with the latest Ardour (4.7).
I tried to follow the debugging instructions, but Ardour crashes before it can open a session when I do.
Based on what Paul said, it looks like I might have to live without it.
OK, I got the debug info via the second method. Here’s the output:

Does that help?
I just built the git version and installed it, but it is the same.
You need to run the command thread apply all bt inside gdn to get a useful backtrace.
