It packages the assembler, linker, object-file tools, and ELF inspection utilities that usually sit underneath a cross GCC. ### プロジェクトの歴史 GNU Binutils collects the binary tools of the GNU toolchain. The GNU project page names ld, as, and gold as the main programs and lists utilities such as ar, nm, objcopy, objdump, readelf, strings, and strip, backed by libraries including BFD and opcodes. The January 1987 GNU bulletin already described a GNU assembler, GNU ld in regular use, and object-file management utilities. The later Binutils project made those pieces a coherent release stream, with Sourceware-hosted documentation, release branches, release tags, and the shared binutils-gdb source repository. ### 採用の歴史 Binutils adoption follows the adoption of GNU compilers and Unix-like package systems: assemblers and linkers are needed for building operating systems, libraries, embedded firmware, and cross targets. The GNU page explicitly states that Binutils' main reason for existence is giving GNU and GNU/Linux the facility to compile and link programs. The i686-elf-binutils formula is part of the package-manager tradition of target-prefixed toolchains. Homebrew identifies it as GNU Binutils for i686-elf cross development and ships prefixed commands including i686-elf-as, i686-elf-ld, i686-elf-objcopy, and i686-elf-readelf. ### 使われ方 In an i686-elf cross toolchain, Binutils usually comes before GCC: the assembler and linker are required to build or use a cross compiler, and tools such as objdump, readelf, nm, and objcopy inspect or transform ELF artifacts. The package is most useful in bare-metal, kernel, bootloader, and low-level systems work where output objects target i686-elf rather than the host machine's native ABI. ### パッケージ好きにとっての重要性 Package nerds care about i686-elf-binutils because it is the small foundation layer of a cross toolchain. A working target-prefixed Binutils package lets the rest of the stack use predictable names and keeps host and target object formats from being confused. It is also a good example of why package managers expose cross tools as separate formulae: the upstream source is the same as GNU Binutils, but the configured target changes the command names and the artifacts users can produce. ### タイムライン - 1987: GNU's bulletin described GNU assembler work, GNU ld in regular use, and object-file utilities. - 1998: The GNU Binutils web page copyright history begins on the GNU project page. - 1999: Historical Binutils mailing lists gas2 and bfd were superseded by the binutils list, according to the GNU project page. - 2008: gold was added to Binutils as an ELF-only linker. - 2026: Homebrew packaged i686-elf-binutils as the Binutils layer for i686-elf cross development. ### Related projects - GNU GCC commonly consumes the target assembler and linker supplied by Binutils. - GDB shares the binutils-gdb repository; elfutils and LLVM tools occupy adjacent object-file and linker-tooling space. ### ソース - - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** i686-elf-binutils - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 関連リンク - [Terminal utility packages](https://pkg.so/ja/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://pkg.so/ja/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://pkg.so/ja/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://pkg.so/ja/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [zstd](https://pkg.so/ja/brew/zstd/) - Runtime dependency declared by Homebrew. - [pkgconf](https://pkg.so/ja/brew/pkgconf/) - Build dependency declared by Homebrew. - [texinfo](https://pkg.so/ja/brew/texinfo/) - Build dependency declared by Homebrew. - [i686-elf-gcc](https://pkg.so/ja/brew/i686-elf-gcc/) - Popular package that depends on this formula. - [arm-none-eabi-binutils](https://pkg.so/ja/brew/arm-none-eabi-binutils/) - Shares the same upstream homepage. - [aarch64-elf-binutils](https://pkg.so/ja/brew/aarch64-elf-binutils/) - Shares the same upstream homepage. - [x86_64-elf-binutils](https://pkg.so/ja/brew/x86-64-elf-binutils/) - Shares the same upstream homepage. - [riscv64-elf-binutils](https://pkg.so/ja/brew/riscv64-elf-binutils/) - Shares the same upstream homepage. - [m68k-elf-binutils](https://pkg.so/ja/brew/m68k-elf-binutils/) - Shares the same upstream homepage. - [arm-linux-gnueabihf-binutils](https://pkg.so/ja/brew/arm-linux-gnueabihf-binutils/) - Shares pkgdb curated category or tags: assembler, binutils, cli, cross-compilation, developer-tools. - [mipsel-linux-gnu-binutils](https://pkg.so/ja/brew/mipsel-linux-gnu-binutils/) - Shares pkgdb curated category or tags: assembler, binutils, cli, cross-compilation, developer-tools. - [mips-linux-gnu-binutils](https://pkg.so/ja/brew/mips-linux-gnu-binutils/) - Shares pkgdb curated category or tags: assembler, binutils, cli, cross-compilation, developer-tools. - [x86_64-linux-gnu-binutils](https://pkg.so/ja/brew/x86-64-linux-gnu-binutils/) - Shares pkgdb curated category or tags: assembler, binutils, cli, developer-tools, linker. ## Combined YAML source View the package source record on GitHub.
