Issue #20506 has been reported by schneems (Richard Schneeman). ---------------------------------------- Bug #20506: Failure compiling Ruby 3.4.0-preview1 on aarch64 on a mac and linux (Ubuntu 24.04) https://bugs.ruby-lang.org/issues/20506 * Author: schneems (Richard Schneeman) * Status: Open * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I was unable to compile Ruby 3.4.0-preview1 on Ubuntu 24.04 via Github Actions. As the logs are not retained indefinitely here's a link to the compilation failure: https://gist.github.com/schneems/bc6bdd6fba08ff6bfdd1bce8d76c457d The relevant errors seem to be in linking yjit: ``` touch yjit/target/release/libyjit.a partial linking yjit/target/release/libyjit.a into yjit/target/release/libyjit.o linking miniruby /usr/bin/ld: yjit/target/release/libyjit.o: in function `__multc3': /cargo/registry/src/index.crates.io-6f17d22bba15001f/compiler_builtins-0.1.108/./lib/builtins/multc3.c:33:(.text.__multc3+0x30c): undefined reference to `__builtin_copysignq' /usr/bin/ld: /cargo/registry/src/index.crates.io-6f17d22bba15001f/compiler_builtins-0.1.108/./lib/builtins/multc3.c:34:(.text.__multc3+0x394): undefined reference to `__builtin_copysignq' /usr/bin/ld: /cargo/registry/src/index.crates.io-6f17d22bba15001f/compiler_builtins-0.1.108/./lib/builtins/multc3.c:42:(.text.__multc3+0x7f4): undefined reference to `__builtin_copysignq' /usr/bin/ld: /cargo/registry/src/index.crates.io-6f17d22bba15001f/compiler_builtins-0.1.108/./lib/builtins/multc3.c:43:(.text.__multc3+0x864): undefined reference to `__builtin_copysignq' /usr/bin/ld: /cargo/registry/src/index.crates.io-6f17d22bba15001f/compiler_builtins-0.1.108/./lib/builtins/multc3.c:47:(.text.__multc3+0x8c4): undefined reference to `__builtin_copysignq' /usr/bin/ld: yjit/target/release/libyjit.o:/cargo/registry/src/index.crates.io-6f17d22bba15001f/compiler_builtins-0.1.108/./lib/builtins/multc3.c:38: more undefined references to `__builtin_copysignq' follow collect2: error: ld returned 1 exit status make: *** [Makefile:298: miniruby] Error 1 /tmp/lib/build_script.rb:118:in `pipe': Command failed debugflags="-g" ./configure --disable-install-doc --prefix /tmp/d20240524-1-bdq0bj/prefix --enable-load-relative --enable-shared --enable-yjit && make -j16 && make install (RuntimeError) from /tmp/lib/build_script.rb:158:in `block in build' from /tmp/lib/build_script.rb:152:in `chdir' from /tmp/lib/build_script.rb:152:in `build' from /tmp/lib/build_script.rb:65:in `block in run_build_script' from /usr/lib/ruby/3.2.0/tmpdir.rb:94:in `mktmpdir' from /tmp/lib/build_script.rb:61:in `run_build_script' from /tmp/build.rb:8:in `<main>' ``` Here's the GHA link: https://github.com/heroku/docker-heroku-ruby-builder/actions/runs/9225538149.... This is the Dockerfile for Ubuntu 24.04 https://github.com/heroku/docker-heroku-ruby-builder/blob/73bdda974811717bac.... I'm able to reproduce the failure locally: ``` $ git clone https://github.com/heroku/docker-heroku-ruby-builder $ cd docker-heroku-ruby-builder $ export DOCKER_DEFAULT_PLATFORM=linux/arm64 $ bin/activate_docker heroku-24 $ bin/build_ruby heroku-24 3.4.0-preview1 # Fails ``` Full output https://gist.github.com/schneems/cfa21847228d48e6bbe27463deae6745. I'm also seeing failures when using `ruby-install` on my mac (ARM), the error message is different so I'm not sure if it's the same problem or unrelated: https://gist.github.com/schneems/12af87e967126c7bfa319645b00015b3 -- https://bugs.ruby-lang.org/
