Before we can start make sure you have a recent Linux distribution. In this guide we are using Ubuntu 22.04.3 LTS. We need to update our package manager and install git, build-essential, meson and ninja-build:
sudo apt update
sudo apt install git
sudo apt install build-essential meson ninja-build
Now that we have git we can clone the Warthog repository from GitHub:
git clone https://github.com/warthog-network/Warthog
A new directory should be created, let's cd into it and run meson build to create a build directory named build:
cd Warthog
meson build
When you run the meson build command for the first time some extra dependencies will be downloaded so it might take a while. Now we have a build directory within the Warthog directory so we cd into it and start compilation with ninja:
cd build
ninja
Congratulations! You now have compiled the Warthog C++ source. But wait - there is a problem: we did not enable compiler optimizations. In meson compiler optimizations need to be explicitly enabled with the --buildtype=release flag. Then the compiled executables and libraries will be more efficient. This is important for mining because you will get better hashrate with optimized compilation.
So let's do this again, we will go up one directory and delete the build directory again. Then we recreate it but this time with the --buildtype=release option and compile again with ninja:
cd ..
rm -rf build
meson build --buildtype=release
cd build
ninja
Note that now meson reports it has set buildtype: release.
After compilation finished successfully we can have a look at the compiled artifacts: Warthog currently compiles a node, a wallet and a miner. They are generated in the src directory within the build directory. Have a look:
cd src/
ls
Now cd into the node directory and view its contents:
cd ~/Warthog/build/src/node/
ls
There is the node named wart-node, let's start it:
./wart-node
The node starts syncing. The node needs to be running and synced while we are using the wallet and miner.
Below we will explain how to create a wallet file and send coins. Go to into the wallet directory and check the contents.
cd ~/Warthog/build/src/wallet/
ls
You should see an executable named wart-wallet. Now let's create a new wallet
./wart-wallet -c
A new wallet called wallet.json file is created. It is not encrypted and other programs on your computer can steal it. Back it up. Don't show it to anyone. The private key can be used to restore the wallet.
To print your address use the command
./wart-wallet -a
Now let's send some coins:
./wart-wallet -s
The wallet asks for the address you want to send to, the fee and the amount. You can type in values like these: Then confirm with "y" and press enter. Of course you cannot send because your wallet address has no coins yet.
For more information on how to use the wallet read the --help section:
./wart-wallet --help
Note: For efficient mining you should have compiled the source code with the meson option --builtype=release as explained above.
First cd into the miner directory and check its contents:
cd ~/Warthog/build/src/miner/
ls
The miner executable is called "wart-miner".
To start mining on CPU you have to supply an address it shall mine to. Furthermore you need to have the node program running in another terminal. The command to mine to the address 537a675aa2d7fa13ea2f0743690c275225af0ab2caf9ee09 is
./wart-miner -a 537a675aa2d7fa13ea2f0743690c275225af0ab2caf9ee09
You need to place your own address into this command.
The miner runs until you stop it with CTRL+C.
By default only the miner compiles only CPU mining functionality. However GPUs are more efficient for mining Warthog, and CPU should not be used for mining.
To enable GPU mining we have to configure the build directory:
cd ~/Warthog/build/
meson configure -Denable-gpu-miner=true
Now ninja executed in the build directory will emit an error because you do not have OpenCL installed. Furthermore meson needs pkg-config to locate the OpenCL headers. Install these dependencies with this command:
sudo apt-get install opencl-headers ocl-icd-opencl-dev pkg-config
Now we can compile again with GPU miner support:
cd ~/Warthog/build/
meson configure -Denable-gpu-miner=true
Compilation should succeed now and meson "User defined options" should list "enable-gpu-miner: true".
To mine on your GPUs you still need to do one thing: you need to install GPU drivers with OpenCL support.
You can check if your GPU has a working OpenCL support with the clinfo command. Install this program with
sudo apt install clinfo
Then start it by typing
clinfo
In our case we don't have any GPU drivers installed that support OpenCL:
The installation procedure depends on your GPU vendor.
Our GPU is an AMD Radeon RX 5600 XT but clinfo does not detect any OpenCL installation for it yet. Visit the AMD support site https://www.amd.com/en/support and select the GPU model:
Then we need to install the downloaded deb package.
sudo amdgpu-install --usecase=workstation,rocm,opencl --opencl=rocr,legacy --vulkan=pro --accept-eula
This will command will take a while downloading and installing more than 2GB worth of packages.
Now try clinfo agian:
The AMD OpenCL platform is now detected but there are no devices. This is because you need to add your user to the render group:
sudo adduser $USER render
Now reboot your system. If you try clinfo again you now see the GPU device:
The warthog miner can now mine in GPU mode:
First download your driver from https://www.nvidia.de/Download/index.aspx?lang=en-us by selecting your GPU model and clicking on "Aggree Download".
The downloaded file is a sh script and we need to make it executable. So we navigate to the Downloads directory and execute
chmod a+x NVIDIA-Linux-x86_64-535.112.01.run
Of course you need to insert your exact filename here.
This means we need to execute the script no a lower run level without an X server running. In addition we must blacklist the default nouvaeu driver with this command:
echo -e "blacklist nouveau\noptions nouveau modeset=0" | sudo tee /etc/modprobe.d/blacklist-nouveau.conf
Now reboot your system. Once rebooted you should switch to a lower run level. To do this press the three keys CTRL + ALT + F3 at the same time. You should see a black screen with login prompt like this:
Ubuntu 220.4.3 LTS pc tty3
pc login: _
Log in with your user name and password and then switch to a lower run level with
sudo init 3
You can now start the installation as above, navigate to the Downloads directory and start the installation:
cd ~/Downloads
sudo ./NVIDIA-Linux-x86_64-535.112.01.run
You should see these screens, just select "Confirm installation", then "Yes", "Yes", "OK".
Now that the NVIDIA driver installation is complete restart your system again you should be able to see your device in the clinfo command:
Now you can mine on your NVIDIA GPU!
