• At least 80 GB of remaining hard disk space for downloading and compiling source codes.
• At least 16 GB of RAM

Operating system requirements

You need to run a 64-bit Linux distribution on the development workstation.

Install required software packages

Use Ubuntu 22.04 to compile openvela. Run the following command to install the required packages on Ubuntu 22.04:

sudo apt install \
bison flex gettext texinfo libncurses5-dev libncursesw5-dev xxd \
git gperf automake libtool build-essential gperf genromfs \
