Hopefully this will be as simple as running ./get_started_linux.sh
Beware that this script is installing dependencies and will request sudo access.
If that is not ok, please open the script and see what it wants to install.
The script also installs Silice on the system, using standard paths (/usr/local/bin and /usr/local/shared/silice).
Finally, the script appends paths to .bashrc.
The get_started_linux.sh script calls the scripts install_dependencies_*.sh to install dependencies. It attempts to detect your distrib to call the corresponding dependencies installation script, but if that fails you may have to manually install the dependencies. In such a case, please refer to the script's contents to see what is needed. Note that the Java jre/jdk are only required for compilation.
The script also downloads and sets up pre-compiled binaries for the FPGA toolchain (from oss-cad-suite). These are placed in /usr/local/shared/silice, and environment variables are set by adding a line to the user's .bashrc.
Time to run a few tests and start having fun!
