Issue #21845 has been updated by nobu (Nobuyoshi Nakada). [GH-15913](https://github.com/ruby/ruby/pull/15913) ---------------------------------------- Bug #21845: Need to rebuild C extension of bundled gems after bumping RUBY_ABI_VERSION https://bugs.ruby-lang.org/issues/21845#change-116179 * Author: hsbt (Hiroshi SHIBATA) * Status: Open * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN ---------------------------------------- I have encountered an issue where fiddle tests are not executed when running `make test-bundled-gems`, so I investigated the conditions for reproducing the issue. It caused by `RUBY_ABI_VERSION`. If I bumped `RUBY_ABI_VERSION` to `2` from `1`, we can't load `.bundle/extensions/arm64-darwin-25/4.1.0+2/fiddle-1.1.8/fiddle.bundle` ``` diff --git a/include/ruby/internal/abi.h b/include/ruby/internal/abi.h index e6d1fa7e8f3..0c99d93bf9b 100644 --- a/include/ruby/internal/abi.h +++ b/include/ruby/internal/abi.h @@ -24,7 +24,7 @@ * In released versions of Ruby, this number is not defined since teeny * versions of Ruby should guarantee ABI compatibility. */ -#define RUBY_ABI_VERSION 1 +#define RUBY_ABI_VERSION 2 /* Windows does not support weak symbols so ruby_abi_version will not exist * in the shared library. */ ``` ``` diff --git a/lib/fiddle.rb b/lib/fiddle.rb index f242de8..12b8277 100644 --- a/lib/fiddle.rb +++ b/lib/fiddle.rb @@ -1,7 +1,11 @@ # frozen_string_literal: true if RUBY_ENGINE == 'ruby' - require 'fiddle.so' + begin + require 'fiddle.so' + rescue LoadError => e + puts e.message + end else require 'fiddle/ffi_backend' end @@ -9,6 +13,7 @@ require 'fiddle/function' require 'fiddle/version' + module Fiddle if RUBY_ENGINE != 'ruby' # FFI backend def self.last_error ``` I rebuild ruby with `make -j` and run `make test-bundled-gems`. ``` ❯ make test-bundled-gems BUNDLED_GEMS=fiddle generating known_errors.inc generating encdb.h generating enc.mk known_errors.inc unchanged fetching v1.1.8 ... encdb.h unchanged making srcs under enc making enc generating transdb.h transdb.h unchanged generating makefiles ext/configure-ext.mk making trans making encs ext/configure-ext.mk unchanged generating makefile exts.mk exts.mk unchanged generating known_errors.inc known_errors.inc unchanged checking out v1.1.8 (v=1.1.8) ...
