[2018-04-28 09:58:51.794] [default] [error] OpenCL error: Failed to list OpenCL platforms! (Unknown OpenCL error -1001)
Maybe it's an hardward problem but graphics cards are listed with lspci :
Hmm no... both miners seem to miss the OpenCL driver or the OpenCL ICD ... I think completely re-installing drivers from scratch will solve this.
I can't seem to find the watchdog for Linux in this thread, nor did it come with 0.34?
True, there is none. The Windows watchdog covers most of the Windows runtime bug the miner has, but that are plainly not presend on Linux. The only problem it covers that exist on Linux as well is 0 sol/s, but since Linux does not allow to deactivate a device and reset it completely without reboot that function would not work on Linux. So the simple Linux .sh script almost does all the job the watchdog could do :/
Wouldn't this have more to do with the change in difficulty as opposed to the miner itself?
I also think so... the difficulty is far higher now. The nethash was 50 to 65M when 0.13 was out but 0.21 not yet there. Today its 130 to 150 so the income at the moment is only half and less then back then - at same hash rate. To befair 0.34 computes hashes about 15% faster then the 0.1x versions and is more stable. Anyways... there was a seriozs bug in 0.1x versions causing trouble on pool side. If its ok for you give me a bit and I will put a kind of 0.13b version with that bug patched out here.
