There is a problem with OpenCL that is preventing darktable from starting.

[Myron-S]

Please see the following issue:

darktable.exe caused a Breakpoint at location 00007FFF33DF9052 in module KERNELBASE.dll.
darktable-org/darktable#8700

It appears this is a problem with OpenCLOn12.

[jenatali]

Thanks for reporting. I can reproduce this on my end. This breakpoint is a bug in our OpenCL compiler stack, I'll take a closer look and see if I can get a fix.

[jenatali]

Yep, I see the problem. Seems simple enough to fix: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/10303. Once that's reviewed and merged I can see about pushing out an updated version of the OpenCL and OpenGL Compatibility Pack. In the meantime, you can uninstall that "app" to work around this issue.

[jenatali]

A new compatibility pack is being published through the Store right now (version 0.2104.7.0 or 1.2104.7.0) which should resolve this for you. Please reactivate if it doesn't.

[Myron-S]

Updated the compatibility pack. Darktable lives again :-)

[EricBright]

The same issue seems to be back (at least in my case). The installed version of my OpenCL™ and OpenGL® Compatibility Pack is 1.2201.1.0. This might be a regression. What do you think? BTW, there seems to be no way for me to uninstall the pack temporarily via the Store. I have no idea why.

[BobSouza]

I am also seeing it.
this is darktable 3.8.1 reporting an exception:

darktable-cltest.exe caused a Breakpoint at location 00007FFC53E85A34 in module CLOn12Compiler.dll.

Looks like it's having trouble compiling 'blendop.cl

[jenatali]

Thanks for reporting. I'll try to get to it soon.

[Myron-S]

Problem still exists.

[jenatali]

Sorry for the delay. I've root caused this: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/17246/diffs?commit_id=9f64d07f21e83e0140254536e7dfc803200a693a. The problem is that the kernel contains unused image args, which is the same as #35.

[Myron-S]

Just a question born from curiosity. How long might it take before the compiled app is available on the Microsoft App Store?

[jenatali]

Hopefully today or tomorrow.

[jenatali]

The update should be live.

[Myron-S]

Is the version of the update 1.2206.5.0? If it is then the fix has not worked. If that's not the right version then the update is not yet live as I've just now reinstalled the compatibility pack and DarkTable is refusing to start.

Ack, looks like there was an ABI update I missed from the compiler, so an update to this runtime is needed in addition to the compiler. Let me fix that...

[jenatali]

Wow, things rotted quite a bit. I've pushed several fixes to master, will go ahead and push a new package.

[EricBright]

Here is the report from my installation:

darktable_bt_2QRKO1.txt

[jenatali]

Ok, this should be properly fixed by 1.2206.6.0. That one's verified to be working for me instead of just spot-addressing the cause of the earlier crash.

[oscarbg]

@jenatali for whatever reason on my system doesn't find any update from 1.2205.1.0.. can make 1.2206.6.0 a github release?

[Myron-S]

@oscarbg Try uninstalling the compatibility pack and then reinstalling. That might work.

[jenatali]

@jenatali for whatever reason on my system doesn't find any update from 1.2205.1.0.. can make 1.2206.6.0 a github release?

I didn't update the package source for Windows insiders, but my expectation was that the higher-numbered package from the non-flighted channel would be offered instead. I'm publishing the package to insiders as well, should be up in an hour or two.

[EricBright]

1.2206.6.0 version fixed the issue like a charm!

[oscarbg]

thanks @jenatali for the release..
