Clone SCST Source Code + +Download the SCST source code from the official repository: + +```bash +cd /tmp +git clone https://github.com/SCST-project/scst.git +cd scst +``` + +### 4. Build SCST Packages + +Prepare the build and create Debian packages: + +```bash +make 2release +make dpkg +``` + +The `make 2release` command prepares the source tree, and `make dpkg` builds the Debian packages. This process takes approximately 2-3 minutes. + +Build output will be in `/tmp/scst/dpkg/` directory. + +### 5.
