Couldn't find the answer on here...

So, I'm getting this error in a loop:

[2018-02-22 20:52:15] Error -11: Building Program (clBuildProgram)

It tries this for a while, then gets to:

2018-02-22 20:52:15] OCL 0: Failed to load kernel
[2018-02-22 20:52:15] OCL 0 failure, disabling!

before restarting the process.

What do I need to do to fix this?

FabulousPanda

Which miner and algorithm are you using?

DrJ30772

bfgminer for Mac OS X, and I was running the Scrypt algorithm.

FabulousPanda

I've never seen that before. Are you using the binary included with MacMiner or the standalone version? It looks as though you're missing the OpenCL driver which should be installed on all macs... It might be work opening disk utility and running first aid on your startup disk.

BoredInTucson

I see this also, and I'm trying to run the xmr-stak-amd for macOS. The directory is there, but there is no file for cl_kernel.ptx12.pch

FabulousPanda

What version of macOS and what hardware (especially GPU) are you guys using? If we can find what you have in common we can probably find the cause of the problem.

DrJ30772

I'm on 10.13.3, and I have a Nvidia GTX 970

BoredInTucson

macOS High Sierra 10.13.3, and an AMD Radeon RX 580 8GB

FabulousPanda

Hmm. Are you using the standalone bfgminer binary or the one in MacMiner and do you get different results using MacMiner 1.5.62 and 1.5.57?

DrJ30772

I was using the one in MacMiner. I'll let you know about 1.5.57

DrJ30772

Hmm. Nope. Switching to 1.5.57 didn't change anything.

Here's the log up until the big error, repeat, error, repeat.

FabulousPanda

Thanks for trying. Unfortunately I've no idea what's going on there! I don't have that .pch file either but it's not looking for it on my machines.

DrJ30772

Thanks for looking at it! Good luck on your future mining projects!
