1  Alternate cryptocurrencies / Altcoin Discussion / Re: [LTC] Cudaminer setup on Linux howto on: March 30, 2014, 04:30:15 PM
Excellent guide!
trying to use it to compile my own cudaminer...first I was getting some errors as CUDA toolkit was missing (The original thread is only referring to few simple commands yet the prerequisities have to be met... so this is how I found this post and with the helf of this got CUDA 5.5 installed.
Despite the guide is little older, I tried to follow to get Cudaminer compiled on my Ubuntu 13.10, yet I'm stucked with the below error...

Code:
root@DuxfordUB:/home/honza/CudaMiner# make

went through several posts referring to "DSO missing from command line", but still can't resolve this..

Would an expert be so kind to kick my lazy but in the right direction ? Roll Eyes?

Thanks in advance!!
2  Bitcoin / Pools / Newbie question - rpcminer-cuda setup *RESOLVED * on: March 22, 2014, 09:54:58 AM
Hi All,

I'm all new to this, so please bear with me... trying to setup for mining at Slush's pool more for fun and to understand how this works... I'm trying to configure with rpcminer-cuda taken from here:https://bitcointalk.org/index.php?topic=281043.0

All seem to run (anyway it pretends to calculate something and I see a load on my PC), however my worker is not updated with any results submitted to pool... The miner is reporting constantly messages similar to this:

Code:
2014-03-22 10:42:04: Listener for "test": New starting nonce = 0x273A0A12
2014-03-22 10:42:04: Listener for "test": New starting nonce = 0x201EF5E8
2014-03-22 10:42:04: Listener for "test": New starting nonce = 0x1FEC6E3C
2014-03-22 10:42:14: Listener for "test": New starting nonce = 0x1FEB06E9
2014-03-22 10:42:14: Listener for "test": New starting nonce = 0x27076EB5
2014-03-22 10:42:24: Listener for "test": New starting nonce = 0x2739FFD0
2014-03-22 10:42:24: Listener for "test": New starting nonce = 0x201EF59F
2014-03-22 10:42:35: Listener for "test": New starting nonce = 0x2708E001
2014-03-22 10:42:35: Listener for "test": New starting nonce = 0x273A0A12
2014-03-22 10:42:35: Listener for "test": New starting nonce = 0x201EF5E8
2014-03-22 10:42:45: Listener for "test": New starting nonce = 0x1FEC6E3C
2014-03-22 10:42:45: Listener for "test": New starting nonce = 0x1FEB06E9
2014-03-22 10:42:55: Listener for "test": New starting nonce = 0x27076EB5
2014-03-22 10:42:55: Listener for "test": New starting nonce = 0x2739FFD0
2014-03-22 10:42:55: Listener for "test": New starting nonce = 0x201EF59F
2014-03-22 10:42:55: Listener for "test": Nonce = 0x2529FF58
2014-03-22 10:42:55: Listener for "test": Server sent: {"error": null, "id": 1, "result": false}

the rpcminer is run with following command:
rpcminer-cuda.exe -user=xxx -password=yyy -url=http://api2.bitcoin.cz:8332 -workrefreshms 100000

It appears as if the miner gets the data (?) yet any result submitted is not accepted at the server (Server sent: {"error": null, "id": 1, "result": false})?

What is wrong with the params and can rpcminer-cuda be used with the Slush pool at all??

Thanks in advance for pointing me to the direction to go!

** RESOLVED **
Seem like the rule of thumbe that when you post a question on a forum, the answer is found a minute later.. It runs fine now, the stratum porxu has been missing in my setup which gave the error!
