I think that this was fixed in 3.4.1, can you try that version?

Nevermind, I thought you was using 3.4, btw I thought this was fixed recently.

Dear Alessandro,

as I am encountering the same problem, please let me comment.

I am using QGIS 3.4.1 64 bit on Windows 7 x86_64

- I installed (updated) QGIS 3.4.1 via OSGeo4W installer
- I have two graphic cards: Intel(R) HD Graphics 3000 and NVIDIA GeForce 610M
- regarding the SDKs I assume the answer is no, but telling the truth I do not know how to check it
- OpenCL.lib is absent
- OpenCL.dll is present in the C:\Windows\System32 directory

Hope this helps

@Antonio: your problem has nothing to do with this issue, the error comes from a python plugin.

With Nvidia quadro k2000 opencl there is not crash

@Daria Svidzinska sorry for the delay, I'm not a windows developer so I'm a bit in the dark here, what I understood is that the OpenCL.dll library is installed by QGIS and copied to C:\Windows\System32 directory if it's not there, what I suspect is going on here is that QGIS is picking up the wrong library, so I would suggest you to try to rename/copy your C:\Windows\System32\OpenCL.dll somewhere, and try to reinstall QGIS, then check if a new C:\Windows\System32\OpenCL.dll was installed and see if that solves the issue.

It's copied there if it exists there and the existing copy is older (by version number within the DLL) than the copy included in QGIS (see dllupdate.cpp - committed just yet there. source also included in msvcrt-1.0.3-1)

@Alessandro Pasotti, I did what you had suggested, but it didn't help.

I temporarily moved OpenCL.dll to another folder and reinstalled QGIS via OSGeo4W. The new OpenCL.dll was not created in the C:\Windows\System32\, and QGIS still crashes when I try to open Settings > Options.

I also tried to reinstall QGIS without moving OpenCL.dll hoping that it will be updated during the installation, but still no luck.

Ok, I cannot reproduce this issue and I'm not a windows developer, so if we want to try to fix it I need someone to volunteer for some interactive debugging (testing builds and report if they work or not), if you are interested/available please to contact me: elpaso at itopen dot it.

Do you have the GPS information panel open? If yes, can you try to close it (Settings -> Panels -> uncheck the GPS info panel), restart QGIS and open the Options again?

I'm having this problem with 3.4.2 and also with 3.4.1 before. Reinstalled and removed plugins and configs.

To help us debug this, please answer the questions below:
- how did you install QGIS 4.3.1?
- what graphic card(s) do you have?
- do you have any graphic cars SDK installed (from Nvidia, ATI or Intel ?)
- please search your system for the following files:
- OpenCL.lib
- OpenCL.dll

- Install was via OsGeo4W installer, new system, hadn't installed QGIS before, installed togheter with also 2.18 LTR
- Notebook has integratred Intel UHD 630 + Nvidia GTX1050 Ti
- no sdk installed (not consciously at least)
- OpenCL.DLL in c:\windows\system32 + opencl.dll in C:\windows\SysWOW64 + opencl.dll in c:\OSGeo4W64\bin
openCL.lib in c:\OSGeo4W64\lib

Can try to do testing for your request.

@Stefano, first I need to make sure that when QGIS crashes you have a similar stack trace (last line contains clGetGLContextInfoKHR).
If yes, please try the latest nightlies builds of QGIS master (the "dev" builds on OSGEO4W), I've made some changes that might have solved the issue.

If the issue persists, please contact me via email and I'll send you a custom build to test.

When merged, I'll appreciate some feedback from the users that are affected by this issue.

Any feedback? Can I close this issue?

Yes, close, 3.4.3 has not crashed after a week or so of use.
Thank you.

So far, this is what I did with no success.

reinstalled with latest nvidia drivers (clean install of drivers): no difference.
    uninstall opencl runtine 18 for CPU.
    Window safe boot (no opencl device was found) (but no crash) (OpenCL Runtime for CPU, when installed without video driver) does not 
    seem to be identified by Qgis as a valid OpenCL device).  (A Python script (Anaconda Python) indicates that OpenCL for CPU is 
    recognized by the Python environment (as well as the video card when drivers are present)

    File were renamed one at a time with reboot every test.  Problem does not seem to come from those OpenCL.dll.

Could not rename the following files.  I don't believe these files are used by Windows unless it's try to find a driver or trying to roll back an update.

NOT RENAMED "C:\Windows\WinSxS\amd64_dual_rdvgwddmdx11.inf_31bf3856ad364e35_10.0.17134.1_none_eaa56d98f154c735\opencl.dll":

Finally, I renamed C:\Windows\System32\OpenCL.dll" (version 2.1.0.0) to opencl.dll and copied that file to C:\OSGeo4W64\bin\opencl.dll. This resulted in the following error:

Entry Point Not found, The procedure entry point clReleaseDevice could not be located in the dynamic link library c:\OSGEO4W\app\qgis\bin\qgis_app.dll

Entry Point Not found, The procedure entry point clReleaseDevice could not be located in the dynamic link library c:\OSGEO4W\app\qgis\bin\qgis_core.dll

Error loading QGIS, Oops, looks like an error loading Qgis, Details Could not load qgis_app.dll. Window Erro: The specified procedure could not be found. Help: Check c:\OS.. qgis-bin.env for correct environmental paths.

The crash is perhaps related to my Old Video Card, a NVIDIA GTX260. Drivers are the latest (342.01) on DirectX 11.0 but this is not probably too old to really be truly maintained by NVIDIA. I should be able to test with a new RX580 in the next few weeks. Please tell me if you want me to test something else.

Hi,
I would change the status as OPEN as this is still not resolved. Will be happy to help out.
