# NAME

`elf2ecoff` —
convert a NetBSD ELF-format executable to NetBSD ECOFF format

# SYNOPSIS

`elf2ecoff` | elf-file ecoff-file

# DESCRIPTION

Reads a fully-linked ELF executable (such as a linked kernel) and produces an equivalent ECOFF format executable file.

The `elf2ecoff` utility is used to convert native NetBSD ELF binaries to ECOFF format, for compatibility with DECstation diskless-boot PROM code and diskless-boot servers that require ECOFF format binaries.

# SEE ALSO

elf2aout(1), ld(1), kvm(3), a.out(5), elf(5)

# HISTORY

`elf2ecoff` was originally developed for NetBSD/pmax by Ted Lemon and was first distributed with the pmax port of NetBSD 1.1.

# BUGS

`elf2ecoff` assumes there are no multiply-referenced symbols in the input ELF symbol section. It may be necessary to link with `-x` to avoid duplicate symbols.

In some environments, the GNU binutils objcopy(1) utility may be a better solution than `elf2ecoff`.
