ELF2AOUT(1)             NetBSD General Commands Manual             ELF2AOUT(1)


NAME

     elf2aout -- convert a NetBSD ELF-format executable to NetBSD a.out format


SYNOPSIS

     elf2aout [-Os] elf-file aout-file


DESCRIPTION

     Reads a fully-linked ELF executable (such as a  linked kernel) and pro-
     duces an equivalent a.out format executable file.

     The elf2aout utility is used to convert native NetBSD ELF binaries to
     a.out format, for compatibility with bootblocks and kernel-reading utili-
     ties like kvm(3), which currently expect an a.out format kernel.

     The following options are available:

     -O    Produce OMAGIC instead of ZMAGIC binaries which is the default.

     -s    Preserve the symbol table.


SEE ALSO

     elf2ecoff(1), ld(1), kvm(3), a.out(5), elf(5)


HISTORY

     elf2aout was originally developed for NetBSD/pmax by Ted Lemon and was
     first distributed with the pmax port of NetBSD 1.1.


BUGS

     elf2aout assumes there are no multiply-referenced symbols in the input
     ELF symbol section.  It may be necessary to link with -x to avoid such
     duplicate symbols.

     In some environments, the GNU binutils objcopy(1) utility may be a better
     solution than elf2aout.
