I'm a total noob regarding bitcoin mining, I've installed cgminer using apt-get install but I can't get it to work.

I start it with this command:

./cgminer  -o stratum+tcp://www.albamine.net:3333 -u Weblogin.WorkerName -p WorkerPassword

I followed these instructions: (I'm mining for scotcoin.)

  1. Install Ubuntu
  2. Install updates
    sudo apt-get update
  3. Install updates for your graphics card
  4. Install misc packages
    sudo apt-get install gedit git libcurl4-openssl-dev libncurses5-dev pkg-config automake yasm
  5. Edit grub configuration
    sudo gedit /etc/default/grub
    Edit GRUB_TIMEOUT=10 to GRUB_TIMEOUT="10" sudo update-grub
  6. Download ATI OpenCL drivers. Untar it and run the script inside.
  7. Reboot.
  8. git clone git://github.com/ckolivas/cgminer
  9. Download the ADL SDK. Unzip it. Copy the include directory into cgminer, and name it ADL_SDK
  10. Check dependencies for cgminer. cd ~/cgminer ./autogen.sh
  11. Create the build script: CFLAGS="-O2 -Wall -march=native -I /opt/AMDAPP/include/" LDFLAGS="-L/opt/AMDAPP/lib/x86_64" ./configure
  12. make
  13. Run using export DISPLAY=:0; export GPU_USE_SYNC_OBJECTS=1; ./cgminer -n

The first few times I tried I got an error that repeatedly said:

KnC spiL Can not open SPI device /dev/spidev1.0: No such file or directory.

NowI'm getting a terminal that looks like this, and I have no idea. I've googled select sections of the code but can't figure out what it's all about. Any suggestions would be gratefully received. Thanks.

Your system reports: Intel's new Iris Pro graphics.

As far as ubuntu 13.10 was concerned the package cgminer was compiled for nvidia graphics cards and installed the module for ubuntu.

Consider running a system with dedicated GPU w/ PCIe: e. g. nvidia and ATI and possibly compile cgminer by yourself.

I tried bfgminer for ubuntu now, see here: http://jarco.be/install-bfgminer-ubuntu-mint/

...but cannot get it to work for litecoin scrypt right now...

NOW up and running bfgminer compiled for ubuntu 14.04 with howto from here: https://debianhelp.wordpress.com/2012/01/02/bitcoin-mining-in-ubuntu-with-bfgminer/

with some minor changes:

  • installed "bitcoin-qt" instead of "bitcoin"
  • sudo apt-get install uthash-dev
  • ./autogen.sh && ./configure --enable-scrypt --enable-opencl && make
  • modified ".bfgminer/bfgminer.conf" can be pasted here, if you want -> 880kh/s @ ATI Radeon R9 290X

  • Oh I see, it looks like mining for scotcoins might be more involved than I'd expected. I'd hoped it would be the sort of thing I could've done using spare processing power when my laptop isn't busy! Thanks for enlightening me!

  • Furthermore the cgminer versions mentioned on your getting started page are outdated, there is only 4.x available. And these versions do not support GPU mining at all (Con Kolivas writes): Q: What happened to CPU and GPU mining? A: Their efficiency makes them irrelevant in the bitcoin mining world today and the author has no interest in supporting alternative coins that are better mined by these devices.
