I'd like to be able to use this with my local node or at least one in Canada, but it keeps citing a stratum error. These are nodes that work fine in sgminer. I guess I'll have to wait for Nextminer. :/

 Pool stratum auth error: {
   "data": null,
   "code": -32601,
   "message": "Service not found"

Supposedly 3.0.1 fixed that to support p2pool, but apparently not on linux build. I haven't tried windows.

Can someone help me please?

https://postimg.org/image/qxoy4od03/

this happens every 6 hours or less

Same. My workaround (on linux). In a screen session:
Code:
while true; do ./mkxminer -o stratum+tls://vtc.suprnova.cc:5676 -u -p -I 21 --asm | tee /tmp/mkxminer.log; sleep 5; done
And in another screen session:
Code:
while true; do ISODT=$(date --iso-8601=ns); if grep 'server reply - error 301' /tmp/mkxminer.log; then killall -9 mkxminer; mv -v /tmp/mkxminer.log /tmp/mkxminer_${ISODT}.log; else echo $ISODT; sleep 30; fi; done

Keeps it running most of the time. Seriously, this code is pretty bad. Just give up the source so we can fix it? Sigh.

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:

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

32bit compile doesnt work for me on Ubuntu 16.04.03 x86_64.

# ./mkxminer
./mkxminer: error while loading shared libraries: libOpenCL.so.1: wrong ELF class: ELFCLASS64


Code:
$ LD_LIBRARY_PATH=/opt/AMDAPPSDK-3.0/lib/x86 ./mkxminer

...but then...

Code:
[15:20:06 - 0 days 00:00:00] clGetPlatformsIDs error -1001, verify that drivers are installed properly
[15:20:06 - 0 days 00:00:00] Error: GPU devices not found
[15:20:06 - 0 days 00:00:00] Could not find any GPUs, exitting...

I have sgminer working with amdgpu-pro on the 4.4 kernel. I am pretty sure this just needs to be recompiled for 64-bit.
