.Dt ELF2AOUT 1
|
||||
.Os
|
||||
.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 DIAGNOSTICS
|
||||
.Sh SEE ALSO
|
||||
.Xr elf2ecoff 1 ,
|
||||
.Xr ld 1 ,
|
||||
.Xr kvm 3 ,
|
||||
.Xr a.out 5 ,
|
||||
.Xr elf 5 ,
|
||||
.Xr kvm_mkdb 8
|
||||
.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 .
