Introduction

Local nix build for xo libraries. Intended for local development work, with source in immediate subdirectories.

Features

native c++
deterministic simulation
reflection
python bindings

Getting Started

Cmake build

If nix is available, you probably prefer the nix build. Otherwise continue reading..

The cmake build has two phases, because it needs to bootstrap generated xo-cmake-config, xo-build helpers.

$ cd xo
$ PREFIX=/path/to/say/usr/local
# phase 1
$ cmake -B .build0 -S xo-cmake -DCMAKE_INSTALL_PREFIX=${PREFIX}
$ cmake --build .build0
$ cmake --install .build0
# phase 2
$ cmake -B .build -S . -DCMAKE_INSTALL_PREFIX=${PREFIX}
$ cmake --build .build
$ cmake --install .build

Nix Build

Nix build uses toplevel default.nix, along with top-level pkgs/xo-foo.nix for each subproject foo. It doesn't interact with toplevel CMakeLists.txt.

$ nix-build -A xo-userenv
