bad_cast when running FAHclient on fedora 33

Hi,
I am trying to run FAHclient on Fedora 33, and it failed with a bad_cast exception.

FAHClient /etc/fahclient/config.xml
15:59:46:Read GPUs.txt
terminate called after throwing an instance of 'std::bad_cast'
what(): std::bad_cast
Aborted (core dumped)

I tried to run it under gdb and it gives the following stack trace:

My guess is intel integrated GPU is not supported, so I tried with additional argument --gpu=false, but it doesn't help and still gives the same bad_cast error.

Any help with how to troubleshoot this problem will be very appreciated.

Did you try updating your Intel iGPU drivers? That would be a good initial step. The other would be to make sure you are using version 7.6.21 of the FAHClient.

One of the more experienced forum members w/an Intel iGPU (on a Fedora system) may be able to help you more with the driver upgrade process. As I'm primarily using NVidia GPU equipped cards.

Thanks for your fast response.

I am using i915 driver, version 5.9.15-200.fc33.x86_64

lspci -k | grep -EA3 'VGA|3D|Display'
00:02.0 VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07)
DeviceName: Onboard IGD
Subsystem: Dell Device 078c
Kernel driver in use: i915

modinfo i915
......
vermagic: 5.9.15-200.fc33.x86_64 SMP mod_unload
......

I am not sure whether I need to try with a different driver.

I downloaded FAHClient this morning, it is version 7.6.21.

FAHClient --version
7.6.21

Intel iPGUs are very particular about drivers and they're being beta tested. I would recommend you leave the iGP disabled at least until you're able to fold with your CPU (and with an AMD or nVidia GPU, if you have one).

This is what I know:

By the way, is there any way to prevent FAHClient from probing for GPU? I tried --gpu=false, but it is still probing for GPU and getting bad_cast exception. I cannot just remove the OpenCL runtime, as I need it for other programs.
I don't think so.

We don't know what hardware/software you have so anything I suggest is strictly a guess.

The OpenCL that comes from Intel is not the same as the one that comes from other vendors, such as NVidia. If you have the nVidia OpenCL runtime (it comes with the nVidia drivers if you get them from nVidia. I suspect FAH will try to use it instead of the Intel version -- and it might allow FAHClient to believe you have no GPUs. It might also be useful to temporarily remove (rename?) the Intel OpenCL runtime.

Does FAHClient get far enough to produce the top of FAH's log.txt?

Setting gpus='false' might also help.
