Installing ethminer in Ubuntu and Automatically Mine

Since the ethminer repository is read only and I think docs/build.md is missing some issues, I will go through installation process. I am using Ubuntu 22.04 64-bit x86 architecture and RTX3060 GPU.

1. Clone the repository and submodules:

git clone https://github.com/ethereum-mining/ethminer.git
git submodule update --init --recursive

2. Install tools:

sudo apt install build-essential gcc g++ cmake libglu1-mesa-dev freeglut3-dev

3. Install cuda toolkit and nvidia drivers https://developer.nvidia.com/cuda-downloads

4. Compile the project

mkdir build
cd build
cmake ..
make -j4

5. Run it

/home/mining/ethminer/build/ethminer/ethminer -P stratum+tcp://<your_wallet_address>.ethminer_intel:nopass@asia2.ethermine.org:4444

6. Add a crontab job so that you will mine automatically

# run "crontab -e" to edit file
* * * * * tmux new -d -s tmux_mining "/home/mining/ethminer/build/ethminer/ethminer -P stratum+tcp://<your_wallet_address>.ethminer_intel:nopass@asia2.ethermine.org:4444" &> /dev/null

Error 1

The following error happened when I skipped step 2.

Error 2

This one happens when the nvidia driver is already installed. We only need the toolkit, so use flags (as suggested here)

--toolkit --silent --override
