NAME

6       elftoaout - ELF to a.out convertor
7

SYNOPSIS

9       elftoaout [ -b ] [ -o outfile ] [ -V ] infile
10

DESCRIPTION

12       elftoaout  converts  a  32bit or 64bit SPARC ELF image to a.out format.
13       This is needed for SPARC bootstraps, as Sun PROM  expects  a.out  image
14       when booting via net or tape or from the disk. On the disk, most of the
15       people use SILO, which uses elftoaout to create first stage loader, but
16       understands  ELF  format,  so you don't need to convert a kernel if you
17       will boot it with SILO.
18

OPTIONS

20       -b     sun4 format. Unlike other PROMs ( sun4[cdemu] ), sun4 PROM  does
21              not  understand  the  32bit  a.out  header  and thus this option
22              strips the header from  the  image.  Other  PROMs  need  such  a
23              header,  so  use this only if you are building an image for sun4
24              or other  architectures  that  explicitly  reqire  a  headerless
25              image.
26
27       -V     Print elftoaout version and exit.
28
29       -o outfile
30              Specify output file name, instead of the default a.out
31
32       -c     Compute an image checksum and store it in a.out header.
33
34       infile Required  parameter  which  specifies  the  ELF image to be con‐
35              verted.

BUGS

38       This utility can handle just a couple of specific cases needed for ker‐
39       nel  and  SILO conversions, but is not able to to convert all ELF bina‐
40       ries to a.out.  It can only convert static binaries and has a couple of
41       other limitations.
