Ubuntu x64 mining from scratch step by step guide

Code:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libstdc++6:i386

Did this, but libOpencl.so.1 still not found. Reinstalled amdgpu-pro via its install script, but still not found.

Code:

sudo apt install libopencl1-amdgpu-pro:i386 opencl-amdgpu-pro-icd:i386 clinfo-amdgpu-pro:i386

This got it to run. However, it segfaults, but a forked process keeps running, doing nothing. Also, you need to implement something to disable extra nonce for p2pool:

Code:

And I can't seem to get it to run under gdb, not even with no args. It just "exits normally" with no output... do you have some debugger detection going on? Would love to be of more help, but paranoia in the way? This is a single r9-270, by the way, with amdgpu-pro version 17.50-511655.

If I use stratum+tls://vtc.suprnova.cc:5676 it does not segfault, but stratum+tcp://vtc.suprnova.cc:5678 does.

Update: If I leave it running for a while, it still segfaults eventually
