This software use a slighty moddified driver from novak's gekko driver.

I allows working with icarus miner and gekko on same rig.

to build this specific code on linux:

sudo apt-get update -y
sudo apt-get install build-essential autoconf automake libtool pkg-config libcurl4-openssl-dev libudev-dev \
libjansson-dev libncurses5-dev libusb-1.0-0-dev zlib1g-dev git -y

git clone https://github.com/wareck/cgminer-gekko.git

cd cgminer-gekko
sudo usermod -a -G dialout,plugdev $USER
sudo cp 01-cgminer.rules /etc/udev/rules.d/
CFLAGS="-O2 -march=native" ./autogen.sh
./configure --enable-gekko
make
sudo make install
sudo reboot

Command line

 ./cgminer -o pool_url -u username -p password --gekko-compac-freq 200 --gekko-2pac-freq 150 --gekko-newpac-freq 150

For windows users, you can donwload the release zip file

Inside you can find a cgminer_run.bat file and you can adjust you settings.

Nicehash extranonce support

You can use your miner with last extranonce support for nicehash by adding #xnsub at the address end, like this:

./cgminer -o stratum+tcp://sha256.eu.nicehash.com:3334#xnsub -u my_btc_address -p x --gekko-compac-freq 200 --gekko-2pac-freq 150 --gekko-newpac-freq 150

For Raspberry Users :

You may need to use "legacy" version of raspberry OS (32 or 64 bit no matter).
