NAME¶
elftoaout - ELF to a.out convertor
SYNOPSIS¶
elftoaout [
-b ] [
-o outfile ] [
-V ]
infile
DESCRIPTION¶
elftoaout converts a 32bit or 64bit SPARC ELF image to a.out format. This
is needed for SPARC bootstraps, as Sun PROM expects a.out image when booting
via net or tape or from the disk. On the disk, most of the people use
SILO, which uses
elftoaout to create first stage loader, but
understands ELF format, so you don't need to convert a kernel if you will boot
it with
SILO.
OPTIONS¶
- -b
- sun4 format. Unlike other PROMs ( sun4[cdemu]
), sun4 PROM does not understand the 32bit a.out header and thus
this option strips the header from the image. Other PROMs need such a
header, so use this only if you are building an image for sun4 or
other architectures that explicitly reqire a headerless image.
- -V
- Print elftoaout version and exit.
- -o outfile
- Specify output file name, instead of the default
a.out
- -c
- Compute an image checksum and store it in a.out
header.
- infile
- Required parameter which specifies the ELF image to be
converted.
BUGS¶
This utility can handle just a couple of specific cases needed for kernel and
SILO conversions, but is not able to to convert all
ELF binaries to
a.out. It can only convert static binaries and has a couple of other
limitations.
