Wownero uses gitian build process for building the CLI executables. It provides a way to be reasonably sure that the executables are really built from the git source. It also makes sure that the same, tested dependencies are used and statically built into the executable.
This means you can help by building wow locally and checking the produced fingerprints against those provided by wownero.org. You will need 2+ CPUs, 8gb of ram, and 30gb disk space. Follow along for details…
Install Ubuntu 18.04
For everyone to get similar results we use an identical build system. This script is based on Ubuntu 18.04. Install the base system, login with default user. If you have enough resources this works fine in a virtual machine.
sudo apt-get install git make curl docker.io
Add yourself to the docker group.
( Note that this will give docker root access to your system.)
sudo usermod -aG docker $USER
git clone https://git.wownero.com/wownero/wownero
cp wownero/contrib/gitian/gitian-build.py .
./gitian-build.py --setup --docker $YOURGITUSER $VERSION
./gitian-build.py --os lfwm --detach-sign --jobs 2 --memory 7000 --no-commit --docker --build $YOURGITUSER $VERSION
If your build finishes with out fail you will be provided with sha256 output along the lines of:
