When trying to mine equihash, I'm getting: OpenCL Error: clFinish: CL_INVALID_COMMAND_QUEUE (-36)

[rgaufman]

Describe the bug I'm able to mine with the DaggerHashimoto algorithm, with this command:

$ sudo ./ethminer --opencl-device 0 -G -P stratum2+tcp://UNIQUE_BTC_ADDRESS.DaggerMiner@daggerhashimoto.eu.nicehash.com:3353

However, when I try to use equihash, I get the OpenCL error above:

Expected behavior It should mine like it does from the DaggerHashimoto pool.

Desktop (please complete the following information):

• Operating System: Ubuntu 16.04
• Hardware 2 x AMD RX580 8GB
• Ethminer Version: 0.16.0.dev1

Guy is an ETH miner not a ZEC miner ..... You using a bad nicehash port, read your log "Connected to equihash"

[StefanOberhumer]

ethash (ethminer) is a different algorithm than equihash ! See:

• Wiki: ethash
• Wiki: equihash

You can not mine equihash with ethminer !

[StefanOberhumer]

Seems you got the answer in #858 .

Ah, thank you, didn't know they were different 🙈
