To follow up, why is there is a libmolc.so in ISOLDE? I would expect it to be using the one from chimerax.atomic. Perhaps it needs a different name?

[Tristan Croll]

Yes, ISOLDE does have its own libmolc.so (wrapping its own functions using the molc api). Naming it that seemed like a good idea at the time and hasn't caused any trouble to date, but I suppose I should rename it. I don't think that's what's causing the issue here, though. A bit weird - runs fine for me after building against today's daily build. Will rebuild and check again.

[Tristan Croll]

Just reinstalled ISOLDE from the ToolShed for today's build (version 0.91 (2019-07-02)) - works fine for me. Has there been another change in the core API that didn't make it into this build?

[Tristan Croll]

Oh, wait - my *Mac* build runs fine. I see you're on Linux. I've seen similar errors when trying to use ISOLDE with the Ubuntu builds due to ABI incompatibility. Only works with the Generic Linux and CentOS builds due to ABI incompatibility with the Ubuntu compilers.

[pett]

Well, I simply clicked the "Install" button on the toolshed to install it. Is there anything we can do to improve the toolshed's Install behavior on Ubuntu?

[pett]

So if I install Generic Linux rather than Ubuntu-specific ChimeraX, ISOLDE should work then?

[Tristan Croll]

Looks to me like that's the issue here. Just installed today's "Generic Linux" build on my laptop and installed ISOLDE from the ToolShed. Runs without trouble.

[Tristan Croll]

I believe there's a ticket open about that, but I'm afraid I've lost track of the ID. If the ToolShed provides a way to distinguish between builds for different Linux flavours I can see about starting to make matching builds - but to do so will also require me to do the same for OpenMM to avoid having to juggle compiler versions.

[pett]

It's ticket #1673. I'll add a comment to it and close this.
