I just committed a change regarding the /tmp directory, perhaps it will help. smartcoin is meant to be installed and run as user. Here is what I would do:
1) Under user, make sure you clear the data directory:
rm -r ~/.smartcoin
2) Clear out any temporary data:
sudo rm /tmp/smartcoin*
3) Follow the install stuff again. Remove the old smartcoin directory and start again.
4) During the detection of the AMD/ATI SDK detection, there is a bug on some systems which shows two paths on one line. Since Linuxcoin is 64 bit, make sure to leave only the 64 bit relevant path!
5) If after starting things appear not to run, detach from smartcoin (option 3 on the control screen), then run
screen -r miner
This will bring you to the individual miner instances where you can see directly the error output of phoenix
I've reinstalled smartcoin from scratch and re-setup all of my workers.
I was seeing the same symptoms as before (a bunch of "grep" error messages flying across the screen every few seconds, and no miners would stay up)
Then I created a manual profile and selected it, and it works!
I went back to the automatic profile, and it showed the same symptoms.
It seems something's funky with the 'automatic' profile.
Hope this helps you zero in on things. If you need any debug info to help narrow it down, let me know.
Can you double check one thing for me? Go to Configure Miners->Edit and edit the miner you are using. Make sure to answer "y" (yes) when it askes if it is the default miner. (The automatic profile uses the miner flagged as default - it is possible that one isn't flagged as default, or was never flagged initially)
Also, I'm committing a couple of changes that silence grep errors, as there are times during a profile change where grep is looking for files created by the previous profile (they catch up after an interation though). Between the two, I think your auto profile should work normally after this.
Also, if after doing the steps listed above, your miners appear not to be working in automatic profile, here is some troubleshooting help:
1) Detach from smartcoin, then run:
screen -r miner
2) Look in /tmp/ for smartcoin* files. These are the files created from the individual miner instances. You should make sure that they exist, and you can even look at the files themselves to make sure they contain the miner output.
Let me know what you find!
