.Sh NAME
|

.Nm elf2aout
|
|
.Nd convert a NetBSD ELF-format executable to NetBSD a.out format
|
|
.Sh SYNOPSIS
|
|
.Nm elf2aout
|
|
.Ar elf-file
|
|
.Ar aout-file
|
|
.Sh DESCRIPTION
|
|
Reads a fully-linked ELF executable (such as a linked kernel)
|
|
and produces an equivalent a.out format executable file.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility is used to convert native
|
|
.Nx
|
|
ELF binaries
|
|
to a.out format, for compatibility with bootblocks and kernel-reading
|
|
utilities like
|
|
.Xr kvm 3
|
|
and
|
|
.Xr kvm_mkdb 8 ,
|
|
which currently expect an a.out format kernel.

.Sh HISTORY
|
|
.Nm
|
|
was originally developed for
|
|
.Nx Ns Tn /pmax
|
|
by Ted Lemon
|
|
and was first distributed with the pmax port of
|
|
.Nx 1.1 .
|
|
.Sh BUGS
|
|
.Nm
|
|
assumes there are no multiply-referenced symbols in the input ELF symbol
|
|
section.
|
|
It may be necessary to link with
|
|
.Fl x
|
|
to avoid such duplicate symbols.
|
|
.Pp
|
|
In some environments, the GNU binutils
|
|
.Xr objcopy 1
|
|
utility may be a better solution than
|
|
.Nm .
