The OSCAR Project
The OSCAR Project
The latest stable release, OSCAR v1.3.1, is officially supported on Windows, macOS, and Linux (Debian, Ubuntu, Fedora).
If you are using a different operating system, we do not provide support and cannot guarantee compatibility. However, if you still wish to try installing OSCAR, you will need:
It is possible to install OSCAR and its cornerstones only once on your system,
and to let several people use this installation. For that, the following bash scripts can be used.
oscar_systemwide_install),
adjust the paths for the variables julia_for_oscar and central_depot,
and then run the script in a terminal (with administrator rights).
#!/bin/bash
# Specify the intended version of Julia.
julia_for_oscar=/users/oscar/julia-1.8.5/bin/julia
# Specify the intended location of the central Oscar installation.
central_depot=/users/oscar/JULIA_DEPOT
# We will store the necessary artifacts in the
# "architecture dependent location" in Julia's default DEPOT_PATH.
# First determine this path and create the directory if necessary.
# (Here we asume that `DEPOT_PATH[2]` is the architecture-specific
# shared system directory, as documented for the default value of
# `DEPOT_PATH`.)
system_depot=$(${julia_for_oscar} --startup-file=no -e 'println(DEPOT_PATH[2])')
mkdir -p "${system_depot}/artifacts"
# Set the Julia variables that control the location of packages.
# (Do not admit the current user's own depot path.)
export JULIA_DEPOT_PATH=${central_depot}:${system_depot}
# Clean the environment, such that the already centrally installed packages
# get replaced by newer versions if necessary.
# (This is safer than calling `Pkg.update()` in Julia.)
# Then let Julia install and precompile the packages.
