Introduction

The goal of this page is to understand the status of various programming languages and toolchains. It can help people deciding on a programming language to choose or to learn, or enable people to understand where distributions need contributions to support well a language.

It could also contain information on what language works where or if we can target specific operating systems with free software or not.

Toolchain status

Features and languages

Feature Ada C C++ D Erlang Fortran Go Java Objective-C Objective-C++ Rust Unified Parallel C. Vala
Autoconf Yes Yes Yes Fortran 77, Fortran 90, Fortran 95 basic support for gccgo Yes Yes No
Automake Yes Yes Fortran 77, Fortran 9x No with CGJ Yes Yes No partial partial
GCC 12 support[1] Yes Yes Yes Yes No Yes Yes No Yes Yes Work in progress No valac uses gcc
Microcontrollers[2] GCC, SDCC GCC, other? depends on glib
Strict specifications[3] ? Drafts are available gratis, probably not under free licenses.[4] ? ? ? ? ? ? ? ? No[5] ? ?

Bootstraping

Compiler Languages Dependencies
gcc-ada
  • Ada
Depends on gcc-ada
valac
  • vala
valac depends on itself but translated C files are provided by upstream

Build system status

Build system Cross compilation Well supported in distributions
Autotools Yes Yes
setup.py ? Yes

Didstributions status

Guix status

Guix is the most strict FSDG compliant distribution with regard to languages support: it requires the bootstrap process to be reproducible.

While there are still binary compilers being used in the bootstrap process for some languages, other languages are completely bootstrapped from source.

Language Toolchain GNU/Hurd i586 GNU/Linux armv7h GNU/Linux aarch64 GNU/Linux i686 GNU/Linux mips64el GNU/Linux powerpc GNU/Linux powerpc64le GNU/Linux riscv64 GNU/Linux x86_64 Mingw i686 Mingw x86_64
Ada No
C gcc-toolchain Yes Yes Yes Reduced Binary Seed of about 145MiB[6] Yes Yes Yes Yes Reduced Binary Seed of about 145MiB[6] Yes Yes
C# No
Haskell ghc No No No Bootstrapped from ghc-4 binaries No No No No Bootstrapped from ghc-4 binaries No No
Java openjdk ? ? ? bootstraped from source[7] ? ? ? ? bootstraped from source[7] ? ?
Rust rustc No[8] No[8] Bootstrapped from source with mrustc[8] No[8] No[8] No[8] No[8] Bootstrapped from source with mrustc[8] Bootstrapped from source with mrustc[8] No[8] No[8]

Parabola status

Parabola has a policy which requires all the packages to be built from source. But it doesn't have a policy to reduce the size of the bootstrap binaries, so there can be circular dependencies.

Language Toolchain GNU/Linux armv7h GNU/Linux i686 GNU/Linux x86_64
Ada gcc-ada No Yes Yes
C gcc-toolchain Yes Yes Yes
C# mono Yes Yes Yes
Haskell ghc No Yes Yes
Java openjdk Yes Yes Yes
Rust rustc Yes Yes Yes
Vala valac Yes Yes Yes

References

  1. Compared with other compilers like LLVM and rustc, GCC supports many CPU architectures and it's quite well integrated with various other software (gdb, gprof, build systems, etc). It also has long term support in mind as it continues to support other programming language standards. It also has good documentation that explain how it handles C code for instance. In addition it's a GNU project, so it has users freedom in mind. In addition Guix has made GCC bootstrapable from a binary that is less than 1KB, and it doesn't require huge resources to build or bootstrap.
  2. Can we compile code for microcontrollers, if so which compilers are used / necessary for that.
  3. Having a standard or something similar to refer to enables people to write code that can still be used without requiring too much maintenance to adapt to newer compiler versions.
  4. Ideally the specifications should be available under free licenses.
  5. See one of the two talks on rust in GNU cauldron 2022.
  6. 6.06.1 https://guix.gnu.org/en/manual/devel/en/guix.html#Bootstrapping
  7. 7.07.1 In gnu/packages/java.scm icedtea-7 depends on jamvm which depends on jamvm-1-bootstrap which is built from source. The source bootstrap is not architecture specific.
  8. 8.008.018.028.038.048.058.068.078.088.098.10 See supported-systems in the rust 1.54 package definition
