How to compile on a headless Linux server? #23

Closed LoganDark closed 6 years ago

LoganDark commented 6 years ago

Aaaaaaaaaaaa.......... it just won't work. OpenCL won't work with Java.

I have no idea how java development works. Can't you just provide a prebuilt jar?

dmarcuse commented 6 years ago

Prebuilt jar won't work without the OpenCL drivers.

LoganDark commented 6 years ago

I installed the OpenCL drivers though. I just can't get them to work with Java.

dmarcuse commented 6 years ago

If you can't get it to build then it won't run properly even with a prebuilt jar.

LoganDark commented 6 years ago

Sigh. I guess I'm just not supported because I don't run Windows.

dmarcuse commented 6 years ago

Windows is irrelevant, I use Arch Linux and have no issues.

LoganDark commented 6 years ago

Well, it worked once for me on Windows. That was a long time ago.

empirebuilder1 commented 6 years ago

OpenCL drivers can be funky on Linux. I have confirmed that this works on Ubuntu- you may just have a bad driver pack.

nVidia or AMD?

LoganDark commented 6 years ago

My server doesn't have a GPU, only integrated graphics.

empirebuilder1 commented 6 years ago

Then there's your problem. Most of the time iGPU's don't have openCL support, and the few Intel implementations that do are rudimentary (and slow) at best, or somewhat nonfunctional at worst (ala Linux).

BTCTaras commented 6 years ago

If you're trying to mine with integrated graphics, you may be better off CPU mining. 1lann's miner is highly optimized and on some hardware could probably outperform a GPU running turbokrist.

LoganDark commented 6 years ago

Been mining with that miner with 2 spare machines (and occasionally my personal laptop, which outperforms both of them) for days.
