objconv

history

Project history and usage

objconv is Agner Fog's object-file converter and disassembler for x86 and x86-64 platforms. It converts between COFF/PE, OMF, ELF, and Mach-O object formats, can modify symbol names, can build and convert static function libraries across platforms, and can dump or disassemble object and executable files.

Project history

Agner Fog distributes objconv from his optimization software page alongside manuals, vector-class libraries, test programs, and assembly libraries. That context matters: objconv is part of a broader x86 optimization and binary-tooling body of work, not an isolated package-manager utility.

A D language forum thread announced objconv 2.03 on 2008-12-09 and highlighted conversion among OMF, COFF, ELF, and Mach-O plus improved disassembly of OMF COMDAT sections. By 2026, the Homebrew formula used date-based upstream packaging from Agner's zip file, while Debian packaged objconv as versioned source in its utils section.

Adoption history

Homebrew core packaged objconv as a single `objconv` executable and used Agner Fog's upstream zip as the source URL, with stable version 2026-05-14 in the 2026-07-01 formula JSON. Homebrew analytics recorded 491 installs over 365 days, and Debian sid packaged objconv 2.57+ds-1 for amd64, i386, x32, and an ia64 unofficial port.

The package's adoption is niche but durable: object-format conversion is not a mainstream daily task, yet cross-toolchain developers, compiler users, reverse engineers, and assembly programmers still need a compact utility that understands several historical and platform-specific binary formats.

How it is used

Users reach for objconv when object files or static libraries need to cross compiler or operating-system boundaries, when symbol names need adjustment, or when a disassembler is needed for x86-family object code. The official manual also states a boundary: objconv can dump or disassemble executables and shared-library-like files, but it cannot modify or convert them.

The disassembler support listed by the upstream page spans instruction-set families from SSE4 through AVX512, FMA3, FMA4, XOP, and Knights Corner, matching the tool's role in low-level optimization and portability work.

Why package nerds care

objconv is the kind of package that keeps old and mixed binary ecosystems workable. Its value is not broad popularity but format coverage: OMF, COFF/PE, ELF, and Mach-O in one GPL-licensed utility, available through common package managers.

Timeline

2008-12-09: a D forum announcement discussed objconv 2.03 and its cross-format object conversion support.
2026-05-14: Agner Fog's upstream page listed `objconv.zip` with that modification date.
2026-07-01: Homebrew core formula metadata listed stable version 2026-05-14; Debian sid metadata listed objconv 2.57+ds-1.

Related projects

objconv sits near assemblers, disassemblers, linkers, compiler object formats, Agner Fog's optimization manuals, and his assembly/vector tooling. It complements rather than replaces platform-native binutils, llvm-objdump, linkers, and compiler-specific library tools.

security posture

No protected-tool coverage found yet

No matching local secret-handling manifest was found for objconv. Nucleus package metadata is still published here so future coverage has a stable package URL.

Install behavior

No Homebrew post-install hook is recorded in formula metadata.
Homebrew bottle metadata is available for 6 platform targets.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
