🔬 CDetect

Utility for figuring out which compiler and compiler version was used for compiling an executable file for Linux (in the ELF format).

Installation

With Go 1.17 or later:

go install github.com/xyproto/cdetect@latest

Example usage

$ cdetect /bin/sh
GCC 8.1.1

$ cdetect /usr/bin/ls
GCC 8.2.0

$ cdetect testdata/rust_hello
Rust 1.27.0-nightly

$ cdetect go
Go 1.11.2

Features and limitations

• Supports detection of compiler name and version if an executable was built with one of these compilers:
  • GCC
  • Clang
  • FPC
  • OCaml
  • Go
  • TCC (compiler name only, TCC does not store the version number in the executables)
  • Rust (for stripped executables, only the compiler name and GCC version used for linking)
  • GHC
• Works even with stripped executables.
• Should work for recent versions of all of the above compilers. Executables produced with old versions of the compilers may need more testing.
