Then it crashes with the same backtrace.

It is an OpenCL crash upon initialization inside IntelOpenCL64.dll and igdrclneo64.dll, so the problem is in the Intel OpenLC implementation.

You have mentioned that you have an Nvidia Quadro M2200 in the machine: IMHO you should install the Nvidia driver, and that is providing OpenCL and should work.

Is there any specific reason why you installed this Intel OpenCL?

anon41087856 · December 20, 2018, 6:35am

My machine is a Thinkpad mobile workstation and the drivers are in factory state. I never bothered to inspect them in Windows actually, I use it only for CAD softwares and Photoshop. Nvidia drivers are installed. I do everything else on Debian. If it’s a problem of driver on my side, I will let it rest then. I develop and use dt on Linux

FWIW: on linux the intel opencl drivers are actually filtered out and you cant enable opencl with them. something similar is missing for windows I guess.

peterbud · December 20, 2018, 1:44pm

@darix, do you know where it is filtered out in the code?

darix · December 20, 2018, 2:35pm

src/common/opencl_drivers_blacklist.h

peterbud · December 20, 2018, 5:08pm

I see there only two blacklistd: beignet and pocl. Are you sure the Intel OpenCL is also blacklisted?

dutch_wolf · December 20, 2018, 5:21pm

If I remember correctly the beignet driver is the Intel driver (at least under Linux)

Pascal_Obry · December 20, 2018, 8:13pm

yes, beignet is intel but on linux probably not on windows.

There is a new Intel OpenCL called Neo : https://software.intel.com/en-us/forums/opencl/topic/758168

That’s what crashes on my system:

“this driver replaces both the SRB5 closed-source driver (aka Classic) and the Beignet open-source driver.”

It looks to me which also deserves the blacklisting: how can an OpenCL call result in a crash in a driver?

anon41087856 · December 22, 2018, 6:26am

Black magic ? I have no idea…

Pascal_Obry · December 22, 2018, 6:58am

Non compatible API?

It seems darktable for Windows doesn’t support network shares? Even when I map them to Windows drive letters, darktable still doesn’t see them.

junkyardsparkle · December 30, 2018, 2:13am

Could someone please tell me what the Windows equivalent of the ~/.local/share/lensfun directory is for darktable purposes (if there is one)? Thanks.

afre · December 30, 2018, 2:37am

darktable\share\lensfun

Hi Peter
i had some Problem with OpenCl on darktable, the CL test failed. => found opencl runtime library OpenCL.dll.
A Check on C/windows/system32 conformed the missing File.
I did a seach across the C drive and i Found the missing files (OpenCL.dll and OpenCl64.dll) and copy them into the Sytem32 folder
Bingo!!! Now my PictureExport runs like mad!

Thanks for your work!!!

Siggi

Siggi · May 27, 2019, 6:29pm

may be i need to add that the missing files where found in c\windows\system32\driverstore\FileRopository…

have fun!

Hi @dnperfors, have you been able to get the build working with Visual Studio or following the above mentioned instructions using MSYS? I am also interested in this, but haven’t been able get either option working. I will appreciate any insight you can provide.

Not sure if any other windows users have experienced this:

Essentially, I can no longer double-click on an image to view it in darkroom. Double-click from lighttable does not work, nor does double-clicking an image in the filmstrip when already in darkroom.
