libiberty

  • libiberty is not needed as it acts like another libc
  • Does not support shared libraries, and is only available as libiberty.a which many distros remove post build or post install
  • It’s not installed by default nowadays; use —enable-install-libiberty to install it
  • Software that needs libiberty will provide it on their own to prevent version changes
  • gcc and gdb require libiberty from binutils internally:
    • alpine (for cross/system enables libiberty; for toolchain it is disabled explicitly with --disable-install-libiberty and .a is manually deleted)
    • clear (manual install, copy to target dir)
    • dragora
    • t2
    • void (in a separate binutils-devel package)
  • Sabotage disables libiberty, and has a fix for older versions of gnu packages
  • Installing gcc’s internal libiberty will overwrite the more modern/mainstream version from binutils causing gcc to fail with libctf in its second pass (according to Arch)
