FreeBSD Linux

Kernel + boot loader Kernel World ● System libraries Installer ● Toolchain (C,C++) Packages ● ● Services and utilities System libraries ● ● Installer Toolchain (C,C++) ● Services and utilities ● Web servers ● Other languages/toolchains Ports (packages) ● X11 and graphics ● Web servers ● Databases ● Other languages/toolchains ● X11 and graphics ● Databases

4 Rust Cologne 11/8/18 Rust on FreBSD: status

● lang/rust: rust stable, available as package

● Everything you need: rustc, cargo, standard library

● Useful to build other Rust packages ● Rustup support for FreeBSD

● Everything is available

● Clippy-preview ● rustfmt-preview ● Editor/IDE

● No ofcial support for electron (a long story, so no atom or VSCode

● I use vim+rust.vim+YouCompleteMe+syntastic

5 Rust Cologne 11/8/18 FreeBSD package: ports?

● FreeBSD Package: the binary blob that you just install ● FreeBSD Port: the recipe to install the software and/or build the package ● The Port Collection counts ~29K ports ● The Port Collection build system is Makefle based

● Meta build specifcation to support every language/build mechanism

● Autotools, cmake, ninja, maven ● C, C++, Java, go, Rust, python, perl, R, Haskell... ● One structure to build ‘em all

6 Rust Cologne 11/8/18 FreeBSD Port

autotools ports(7)

make fetch make checksum make extract make patch ./configure make configure make make build make install make stage make install/package

7 Rust Cologne 11/8/18 FreeBSD ports & cargo

ports(7)

make fetch => fetch crates make checksum => checksum on crates make extract => tells cargo to use the make patch downloaded crates make configure make build => use cargo to build make stage => use cargo to install make install

8 Rust Cologne 11/8/18 FreeBSD ports & cargo: cargo.mk

● USES= cargo

● make cargo-crates

● An additional target to help maintainer to get the list of crates that has to be added in the Makefle ● make makesum

● A target to automatically compute the source’s checksum ● It takes care of crates as well ● “Hard-to-build” crates are pre-confgured

● The ports collection prefers shared library

9 Rust Cologne 11/8/18 FreeBSD ports & cargo

Real example and code: Easy example: sysutils/potnet Where the magic happens: Mk/Uses/cargo.mk FreeBSD philosophy at work: devel/sccache
