ELF2OLF(1)                 OpenBSD Reference Manual                 ELF2OLF(1)

NAME
     elf2olf, olf2elf - convert between ELF and OLF object module format



SYNOPSIS
     elf2olf [-v] [-o opsys] module [...]
     olf2elf [-v] file [...]

DESCRIPTION
     The elf2olf utility reads the specified ELF version 1 module operands and
     converts them to the default operating system's OLF object module format.
     The olf2elf utility reverses the process.  The module operands are pro-
     cessed in command line order.

     The options are as follows:

     -v      Operate in verbose mode.

     -o opsys
             Specifies the operating system OLF tag opsys as follows:

             The elf2olf and olf2elf utilities exit 0 on success or >0 if an
             error occurred.

BUGS
     The ELF version 1 object module format lacks any real method to determine
     the native operating system for any given binary thus mandating the exis-
     tence of these tools.  The converted binaries created by elf2olf will no
     longer execute on their native operating system, only on OLF enabled
     platforms, although olf2elf will undo the damage.
