ELF2OLF(1) BSD Reference Manual ELF2OLF(1)
elf2olf, olf2elf - convert between ELF and OLF object module format
elf2olf [-v] [-o opsys] module [...] olf2elf [-v] file [...]
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: openbsd OpenBSD netbsd NetBSD freebsd FreeBSD 44bsd 4.4BSD linux Linux svr4 AT&T System V Release 4 esix esix UNIX solaris SunSoft Solaris irix SGI IRIX sco SCO UNIX dell Dell SVR4 ncr NCR SVR4 The elf2olf and olf2elf utilities exit 0 on success or >0 if an error oc- curred.
The elf2olf and olf2elf utilities first appeared in OpenBSD 2.1.
The ELF version 1 object module format lacks any real method to determine the native operating system for any given binary thus mandating the ex- istence 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.
