[Resolved] Rack V2 cannot start on macOS 10.12 or lower

LarsBjerregaard · October 5, 2021, 1:00pm

@vortico I was doing a bit of detective work on the Rack V2 dependencies, to see if I could find something that would inadvertently introduce a minimum MacOS version requirement different from your own.

I see that V2 uses “ghc::filesystem” at version 1.3.6 from 2020.10.10 and quite a few releases have been made since then. Looking at the changelog of the project I saw these (1) two (2) changes from later versions of the project, that seem to revolve around MacOS version detection and handling. Maybe relevant?

And here’s the log.txt from the Mac Pro:

Thanks Henk. Yup, it’s exactly the same content of the error-log as the OP and me.

LarsBjerregaard · October 5, 2021, 5:48pm

Seems that Rack V2 works (1) (2) on 10.13 (High Sierra) so the net of observations is tightening to be: V2 doesn’t run on 10.12 (Sierra) or lower.

LarsBjerregaard · October 6, 2021, 3:33pm

@dronehands Would you consider renaming this topic to: “Rack V2 cannot start on macOS 10.12 or lower” ? We need some more people with eyeballs on this, to substantiate the problem. Thanks.

synthi · October 6, 2021, 4:20pm

I know this ONE!!!

It’s happening for the widgets using OFFSCREENS and disposing the framebuffers in DTOR and happens only when one close the VCVRack closing the window

people should move the destruction of framebuffers into the “onContextDestroy”

the crash happens because somewhere, very deep in the structure there is a reference to some handle connected to the main window but at that time the window is already gone and BOOM !

dronehands · October 6, 2021, 8:54pm

i changed the thread title as requested.

Squinky · October 7, 2021, 12:21am

@robert.kock This sounds like that issue with NoiseDrawer. Do you think this is a better solution? (I don’t know).

Squinky · October 7, 2021, 12:38am

The porting guide says you are not allowed to hold onto off-screen memory at all! but it’s ok since “bitmap loads are cached”. But that does this mean for plugins that draw their own stuff in off-screen buffers???

synthi · October 7, 2021, 7:11am

yes, sure

but I discovered the problem in the v2 and happening only when closing the window (not when, for example, you are deleting a single module)

so I’ve added (imitating the FrameBufferWidget) the onContextDestroy event and adding a delete framebuffer there and setting the member to NULL

of course I continue to have the delete framebuffer in the destructor (testing if != NULL )

after adding that change, all the crash at closing VCVRack are gone

LarsBjerregaard · October 7, 2021, 9:42am

Guys, maybe move these to a seperate topic under development, since it’s a seperate issue? Thanks!

LarsBjerregaard · October 7, 2021, 2:18pm

The tally so far by my count (will keep it updated), as reported in this topic, on the Facebook post, or heard elsewhere:

People with systems where Rack V1 works, and:

Are on macOS 10.12 (Sierra) or lower and Rack V2 can start: None
Are on macOS 10.12 (Sierra) and Rack V2 always crashes on start: 3 people
Are on macOS 10.11 (El Capitan) and Rack V2 always crashes on start: 2 people
Are on macOS 10.10 (Yosemite) and Rack V2 always crashes on start: 1 person

I would call that good evidence that there’s a real problem, with no evidence to the contrary .

robert.kock · October 7, 2021, 4:10pm

I have added a destructor in the widget which solved the crash during exit for the Noisedrawer. There wasn’t one in the past. So that fixed it for me, but I see that is doubted by synthi. I am not sure this is a better solution ( I would call it a workaround?)

Squinky · October 7, 2021, 6:51pm

Yes, there was one. Unique pointer frees the held object in its destructor.

dronehands · October 17, 2021, 11:09pm

The new build for Rack 2 (Rack development blog - #73 by Vortico) crashes upon launch like before.

Squinky · October 17, 2021, 11:18pm

are you sure it isn’t trying to make a patch using modules that are not completely up to date?

dronehands · October 17, 2021, 11:22pm

I dont know what its trying to load because…wait for it… it crashes upon launch. How would i go about testing that?

dronehands · October 17, 2021, 11:36pm

I tried opening the template.vcv file in the Rack 2 program resources folder. In addition to the familiar “VCV Rack has crashed…” message box there is now a dialogue box that reads:

“The document “template.vcv” could not be opened. VCV Rack 2 cannot open files in the “VCV Rack Patch” format.”

Edit: the same template file opens just fine in 1.1.6. seems to be a sample patch with all fundamental modules.

benway · October 18, 2021, 12:12am

Similar crashes, Rack opens but when I click to add a module to an empty patch it goes down. No issue with the previous build. Log file, in case it’s of assistance:

Is that using the 219bbaf1 version of Audible Instruments?
