CL_BUILD_PROGRAM_FAILURE

[th3n3wguy]

Hi guys,
I have a problem with my virtualBox The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) machine.
I'm new to this whole The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali)-Linux and hashcat/hacking topic.
When I try to run hashcat within my VM I get the following error:

'''''''''''''''''''''''''
└─# hashcat -b

hashcat (v6.1.1) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

I got the same error when running the command "hascat -b" in a Parrot OS VM.
The host machine runs Win10.
I have tried to uninstall and reinstall hashcat. Nothing helped.

Can someone help me? Is there a known fix for this?

[undeath]

1. remove pocl and install a proper opencl runtime
2. only run inside a vm if absolutely necessary

[th3n3wguy]

Thanks for your help.
I have solved it. Don't know how this worked, but it did.
I donwloaded the Intel OpenCL runtime (http://registrationcenter-download.intel...4.0.37.tgz) and installed it over the "install.sh". Although i have a AMD Cpu.
Now everything runs perfectly fine.

[HashcatMan2022]

What do you mean you installed it over "install.sh" the install.sh of what exactly?

I downloaded and extracted the tar file. Now what do I do? That is in the The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) machine, not on Windows.

[Snoopy]

Inside the tar.gz there there is a shellscript called install.sh, like the name, i supposse, starts the installer so running

./install.sh

from inside a terminal willl do the trick, beforehand please deinstall pocl,

Aptitude purge pocl or the apt-get alternative, dont know which system k.a.l.i uses
