I've just seen the post, I did a guide for Neoscrypt on sgminer. I added the "wild" kernels to a github. Although, I know FTC members paid Wolf to keep his (main) work for Neoscrypt, in the open source domain. I have been looking closely at the sgminer code, at least to gradually tidyout some of the cruft (algos that never took off), as I found the latest version started to get flaky.
[Guide] How to Mine crypto-currency with Linux on AMD Graphics cards GPU, install sgminer 5.1.2
This guide is for GPU mining with Sgminer 5.1.2 on GNU/Linux (Ubuntu 14.04.0x LTS). It is set up to mine Feathercoin, which uses the neoscrypt algorythm to encrypt each transaction, but will work with multiple algorithms from other alternate currencies, with an appropriate Sgminer config file set-up.
Sgminer 5.1.2 is the same as version 5.1.1, except it has has some additional neoscrypt kernels which kave been let out in the wild and the option to return to version one, which is better with some cards.
See “forked from” on Github, if you want to use the guide on the sgminer-dev source instead.
In general the performance and complexity of GPU mineing comes down to the AMD drivers and lack of support for all previous cards versions in each release. here are also problems where certain versions of the AMD drivers will not work with versions of linux or sgminer.
In order make a stable install which will work with the neoscrypt algorithm, specific versions are used, 14.04 LTS Ubuntu operating system, 14.9 AMD fglrx, 2.9 AMD application SDK and version 6 of AMD’s ADL SDK.
This guide has been tested on R9 2** cards and is optimised for Neoscrypt on R9 280 in the guides default configuration.
#1. install Ubuntu 14.04.0x
Open a terminal and do an update to Ubuntu
Code:
sudo apt-get update
sudo apt-get upgrade -y
Install build essentials and dependencies
Code:
sudo apt-get install -y git curl unzip automake autogen yasm autoconf dh-autoreconf build-essential pkg-config openssh-server screen libtool libcurl4-openssl-dev libtool libncurses5-dev libudev-dev gdebi gedit execstack dh-modaliases lib32gcc1 dkms
sudo apt-get install -y xserver-xorg-core xserver-xorg-video-ati
#2. Manually Install correct AMD Catalyst drivers (14.9)
Code:
sudo apt-get install linux-headers-generic
sudo apt-get purge ‘fglrx*’
sudo rm /etc/X11/xorg.conf
sudo apt-get install --reinstall -y xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg
Download 14.9 driver from AMD :
http://support.amd.com/en-us/download/desktop/previous/detail?os=Linux x86&rev=14.9
Code:
cd ~/
mkdir fglrx4.9
Extract the AMD driver installer
Extract the files and folders from download of the AMD Catalyst™ 14.9 Proprietary Linux x86 Display Driver zip and copy / extract them into the fglrx4.9 directory
run the install commands, after it finishes press exit, then install on the pop up.
Code:
cd fglrx4.9
sudo sh *.run
Initialise the graphics card, install xorg and dependencies.
Code:
sudo aticonfig --adapter=all --initial
sudo aptitude install -yr boinc-amd-opencl opencl-headers mesa-utils libglu1-mesa libgl1-mesa-glx libgl1-mesa-dri
#3. Reboot
#4. install AMD App SDK
Code:
cd ~/
mkdir amd-app-sdk
Download APP-SDK from AMD :
http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/
make sure it is version 2.9 AMD-APP-SDK-v2.9-lnx64.tgz extract it into /amd-app-sdk
Code:
cd amd-app-sdk
chmod a+x *.sh
sudo ./Install-AMD-App.sh
sudo aticonfig --adapter=all --initial
#5. Reboot
#6. Install sgminer 5.1.2
Code
cd ~/
git clone https://github.com/wrapperband/sgminer.git
#Download AMD/ADL_SDK_6.0.zip, extract the 'h files from include to ~/sgminer/adl_sdk
http://developer.amd.com/tools-and-sdks/graphics-development/display-library-adl-sdk/
Make sure it is the version ADL_SDK_6.0
Code:
cd ~/sgminer
git submodule init
git submodule update
autoreconf -i -f
CFLAGS="-O2 -Wall -march=native -std=gnu99" ./configure
make
(sudo make install : optional install)
Check that the build worked
Code:
./sgminer -n
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
./sgminer
#7. Create a sgminer start script
#Create the script file to start sgminer correctly
Code:
nano sgminer.sh
Copy in the script code and customise as required :
#!/bin/bash -
#title :sgminer.sh
#description :Start sgminer
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
./sgminer
#Make the bash script runnable
Code:
chmod a+x *.sh
#8. Run the sgminer script
Code:
cd ~/sgminer
./sgminer.sh
The different coin algorithms are stored in the sgminer/kernels directory. The kernels are created in C for AMD cl graphics processing programming interface. Esencially the GPU speeds up over CPU by parallel processing.
There are four neoscypts available in the 5.1.2, neoscrypt.cl, neoscrypt.v1 and neoscrypt.v2 are marked as such and version 3 which is “optimised” for R9 280 (default neoscrypt kernel) and marked as neoscrypt.280.
There is also a 79XX kernel version, with some of the 290 code replaced to handle older cards, which is included as a separate file neoscrypt.7690.
It is worth experimenting to see which kernel works best with your setup, copy one of the neoscrypt files then run a recompile…
Recompile sgminer after changing the kernel
Code:
cd ~/sgminer
rm *.bin
autoreconf -i -f && CFLAGS="-O2 -Wall -march=native -std=gnu99" ./configure && make && ./sgminer.sh
The configuration file sgminer.conf is stored in the .sgminer hidden directory. Use Ctr-H in Gnome / Nautilus or Alt . in KDE / Dolphin, to show the hidden directories in the home directories.
I have experimented and read about xIntensity, it made no difference to adjust that from 3 for neoscrypt. It gave exactly the same results with raw intensity of 5690.
An example sgminer.conf pointing towards p2pools, just replace the address with your own.
Code :
nano ~/sgminer/sgminer.conf
{
“pools”: [
{
“name”: “Neoscrypt Pool2P”,
“url”: “stratum+tcp://p2pool.neoscrypt.de:19327”,

Yasm? Why yasm? If you're not doing anything with the CPU, like doing algos in assembly language, yasm isn't required if you're not doing that.
